Signs of Autumn: Subtle Clues that Fall is Near or Here

Search for signs of autumn! With this fun nature scavenger hunt idea, children and adults of all ages can learn to notice the universal sensory cues that indicate fall is near, has arrived, or is approaching.

Autumn rarely arrives with a grand announcement. It slips in quietly. The light softens, shadows lengthen, seeds ripen, birds begin migrating, and mornings feel a little cooler. When we slow down and pay attention, these subtle changes reveal that the season is already turning. Learning to recognize autumn’s signs helps children and adults connect what they see outdoors to the broader rhythms of the natural world.

This helpful guide highlights the first signs of fall and the seasonal signs you might notice depending on where you live. One of the most interesting details about these subtle seasonal signs is that they aren’t always the same everywhere; that’s why it’s important to pay attention to the nuances you notice throughout your lifetime and what you experience in parts of the world that are different from yours, as the seasons pass. Holding this nature-focused perspective and finding your place within it can turn an ordinary walk into an opportunity to wonder, explore, ask questions, and discover what is changing right where you live and why right outside your door every day.

Learn more about autumn phenology and how to identify the universal sensory cues that indicate fall is near, has arrived, or is approaching in this informative guide. Afterward, encourage kids and adults of all ages to look for the signs of autumn by becoming more aware of subtle sensory clues as each day turns into the next, with a seasonal scavenger hunt. In a hurry? Skip straight to the list of fall scavenger hunt ideas!

First published on August 15, 2015, this post about the common signs of fall or autumn, along with the accompanying scavenger hunt printables, is regularly updated to keep the content fresh and relevant. You may also enjoy these fall activity ideas with a printable bucket list.

What are the First Signs of Autumn?

The first subtle signs of autumn often appear long before the leaves reach their peak color. Instead, sometimes the first sign of a new season is simply a shift in the light. Sunlight strikes the ground at a lower angle and may take on a warm golden hue. Days typically grow shorter, seed heads dry, certain fruits and nuts ripen, and wildlife behavior slowly shifts.

As the summer heat subsides and cooler temperatures become the norm in late August and early September, many people in more temperate climates can begin to see, hear, feel, smell, and even taste (pumpkin spice, anyone?) what for many are the unmistakable signs of fall. From falling leaves and migrating birds to flannels, boots, and the cozy feeling of cashmere and a hot latte on a chilly day after a long, hot summer, the seasonal sensations and stunning autumn colors make fall a great time to get outside and enjoy nature’s beauty.

Below is a brief overview of some of the most common universal signs that autumn is either approaching or has already arrived. Explore a more detailed explanation of the seasonal clues that signal the change of seasons from summer to fall, and learn about the Signs of Autumn Scavenger Hunt in the sections that follow the quick list of universal fall signs below.

A Few Typical Signs of Autumn or Fall You Might Notice:

The earliest signs of fall may include:

• Softening light.
• Longer afternoon shadows.
• Later sunrises and earlier sunsets.
• Cooler mornings.
• Ripening seeds, fruits, and nuts.
• Changes in birdsong or bird activity.
• Fewer summer insects.
• Dry grasses and fading summer flowers.
• The first leaves changing color.
• Dew, mist, or frost in cooler regions.
• Changes in familiar daily and family rhythms.

How do you know when fall has arrived?

Once fall, or autumn, fully arrives, a variety of sensory cues often appear, including vibrant autumn colors, fall foliage, and other telltale signs, as shown in the photograph below. But fall doesn’t necessarily look the same everywhere, any more than the temperature or time is the same worldwide at any moment. Other parts of the world have entirely different clues that signal the shift from summer to fall.

Autumn Does Not Look the Same Everywhere

The same autumn clues don’t show up everywhere, and the fall signs you notice may be completely different from the vibrant oranges you see in the photo above. Ultimately, the seasonal changes you experience depend on your climate, elevation, latitude, and local ecosystem.

There is no single picture of autumn that fits the whole world. Some places glow with red and golden leaves as shown in the fall photo above, while others experience rainy, dry, or second-growth seasons. Rainfall changes near the equator may be more noticeable than changes in daylight. In warmer climates, autumn may appear in ripening crops instead of falling leaves. While in others, animal movement, softer light, or a slight drop in temperature signals autumn’s arrival.

A wooded grove full of autumn colored descidous trees losing their leaves in the fall, as shown in the images above and below, might be an entirely foreign sight to you, because you might not see a single leaf turn where you live. That’s why it’s important to learn about the autumn signals to look for around you!

Autumn also occurs at different times in the Northern and Southern Hemispheres. While the Northern Hemisphere enters autumn around September, the Southern Hemisphere enters autumn around March. Instead of looking only for familiar fall symbols, notice how the living world changes where you are and note these changes accordingly.

Why Learn to Recognize the Signs of Autumn?

When children learn to recognize seasonal clues, autumn becomes more than an arbitrary date on the calendar. They come to understand that the living world responds to changes in sunlight, temperature, water, and food availability. A ripening acorn, a quieter garden, and a passing flock of birds become interconnected elements of the same seasonal story.

Close observation also strengthens attention, curiosity, and belonging. Children come to know their home landscape and the land they live on in a much more intimate way than merely passing through it. This reflects a central living principle of the Rhythms of Play philosophy: everything, including learning, begins with connection and belonging.

This fall-themed learning activity is ideal for parents, teachers, outdoor programs, homeschooling families, and curious adults who want to learn more about the subtle seasonal changes that occur as summer slowly transitions into fall. Another fun way to teach children about fall and the changing seasons is sharing autumn stories. Here’s an excellent list of fall books for kids that you can use for this purpose.

Signs that autumn or fall is near, on the way, or has arrived:

This educational outdoor activity can help children and adults of all ages develop a deeper connection to nature and the land around them, sharpen their observational skills, and learn to recognize the small changes that occur every day and their significance.

Although the calendar divides the year into four distinct seasons — spring, summer, fall, and winter — subtle changes happen every day. Because these changes don’t happen overnight and instead appear gradually throughout the season, they create a sensory tapestry that signals autumn’s arrival.

As each day passes into the next, these small shifts gradually lead to the upcoming season. Each minor change flows into the next. However, when you look back, you realize how much has actually changed. Typically, the signs of fall begin in late summer, long before the autumnal equinox, and continue well after it, until one day winter arrives and you realize it’s gone.

Noticing Autumn with All Five Senses:

Most lists of autumn signs focus on what we can see, but the changing season can also be heard, felt, smelled, and tasted. Engaging all five senses helps children notice the subtle changes they might otherwise miss.

What Does Autumn Look Like?

Autumn isn’t limited to red and orange leaves. Look for the soft gold of dry grass, dark seed heads, ripe berries, shifting skies, and a warm light of late afternoon that makes it feel like happy hour all day. Even evergreen landscapes reveal autumn through subtle changes in the plants growing beneath and around the trees. In fall, look for:

• Changing leaves.
• Dry grasses and seed heads.
• Ripening fruits, nuts, and berries.
• Lower sunlight and longer shadows.
• Migrating or gathering animals.
• Dewy spiderwebs.
• Fading summer flowers.
• New seasonal blooms.

What Does Autumn Sound Like?

Close your eyes and listen. Does the landscape sound busier, quieter, or simply different? You may hear dry leaves scrape across the ground, seeds tapping against stems, or birds calling to defend their territory. The sounds you hear will vary by location, but changes in the soundscape can be among the earliest signs of a new season. In fall, listen for:

• Leaves rustling or crunching.
• Changing birdsong.
• Migrating flocks of birds calling overhead.
• Wind blowing in dry grasses.
• Nuts or seeds falling from dry stems.
• Rain pattering on leaves.
• Quieter insect activity.

What Does Autumn Feel Like?

Close your eyes and notice how autumn feels against your skin. Crisp mornings, warm afternoons, and cool nights greet many people as fall arrives. Even the sunlight feels less intense at midday than it does in summer. You might feel a light breeze, or a full-blown wind greeting you when you open the door. In fall, notice:

• Cooler mornings.
• Changing variable winds.
• Damp grass or heavy dew.
• Drier air in some regions.
• Rainier conditions in others.
• Warm afternoons followed by cool evenings.
• Different textures underfoot.

What Does Autumn Smell Like?

Autumn brings a mix of changing scents wafting in across the landscape. In fall, notice:

• Damp soil.
• Fallen leaves.
• Rain.
• Ripening fruit.
• Dry grass.
• Wood smoke from chimneys.
• Seasonal foods cooking at home.

What Does Autumn Taste Like?

Autumn can be tasted through the food ripening where you live. Apples, pears, pumpkins, squash, grapes, nuts, root vegetables, and late-season berries are common in many temperate regions. Other climates have completely different autumn harvests. Visit a garden, farm stand, or market and ask, “What’s ripe here now?”

Signs of Fall to Hunt for:

The signs of fall you see are based on the geography of the area and the climate and biome in which you live, or rather, are at the moment, should you be traveling. Therefore, what you see, feel, hear, or experience may differ from what is listed in the signs to look for below.

Of course, different parts of the world will experience signs and characteristics of fall that aren’t on this list. In contrast, people who live near the equator or the North or South Poles may not notice many of these changes.

I’d love to hear all about the seasonal sights you notice appearing around you! Please share any unique, familiar sights, sounds, and sensations of fall you experience where you live.

Signs of Autumn in Sunlight and Weather:

Fall is the season when many people bid farewell to the sweltering summer heat and welcome the brisk, refreshing air of fall. The season’s cool temperatures are perfect for outdoor activities, whether hiking through forests or enjoying a cozy evening around a bonfire.

As the days grow shorter, the nights become longer, and beautiful starlit skies become the perfect backdrop for stargazing. This makes the fall a great time to break out your telescope and learn about astronomy and the celestial wonders above. Here are a few more weather and climate changes that become more likely in many climates, but not all, in the fall:

Possible Weather Changes in the Fall:

• Cooling Temperatures: As summer ends, temperatures typically drop (decrease) from late summer into autumn. In many areas, the days become crisper and cooler, especially in the morning.
• Seasonal Weather Patterns Return: In autumn, weather becomes more variable in many parts of the world. These seasonal patterns are often marked by warm and cold fronts depending on location and climate.
• Variable Winds are Possible: Conditions become breezier in some parts of the world. Wind direction changes, and windy days and seasonally variable weather become common in certain areas.
• Some Climates Get More Rain (Increased Precipitation): Precipitation increases in many areas in the fall, resulting in more rain. In some colder climates, this rain will eventually turn to snow as fall transitions into winter.
• Increase in Stormy Weather Possible: With diminishing sunlight and changing temperatures, some climates see more rain, thunder, and lightning, and hurricanes and tropical storms become more likely in specific parts of the world.
• Morning Dew Becomes Common in Some Places: In the early morning, you may notice dew on grass and spiderwebs, giving the landscape a glistening, fresh feel.
• Some Areas Develop Frost: Occasional frost may appear in certain climates, especially in the early mornings.
• Cloudy Days Become Increasingly Common in Certain Areas: Fog, clouds, and overcast skies tend to increase in some climates as storms approach in the fall. Many coastal areas and places near large bodies of water also develop clouds, overcast skies, or fog.

Sunlight Changes in Autumn:

• Shorter Days: Daylight hours steadily decrease as the season progresses.
  • The sun rises later each morning and sets earlier each night, making each day noticeably shorter and each night darker and longer.
  • You can find the reason for the change in seasons in the fall here.
• The Angle of Sunlight: As the sun’s angle in the sky changes, sunlight comes from a lower angle, creating longer shadows.
  • Daylight softens, and the strength and quality of the sunlight change.
• Golden Hour: More pronounced warm hues during sunrise and sunset, as shown in the photograph below.

Plant Life Signals that Autumn is Approaching:

In the autumn, daylight hours become shorter, and nights become longer. This shift in daylight triggers various natural processes, including the fascinating ways plants and animals prepare for winter. (The signs of autumn in the animal kingdom can be found in the next section.)

As mentioned above, one of the most visible signs of fall is the transformation of leaves from vibrant greens to shades of red, orange, and yellow. This happens when chlorophyll breaks down, revealing the hidden pigments in leaves. The fall is a time of great contrast. While most flowers wither and lose their petals, and many plants go dormant or die in the fall, others bloom and ripen to take their place.

While it may seem like the world is dying around you in the fall, a significant transformation is taking place. Late-blooming fall flowers, such as chrysanthemums, and produce that ripens in autumn become more prominent. In other words, farms, orchards, and forests become abundant with seasonal produce and other treats for humans and wild animals that are only available in the fall. Here’s a more detailed look at some of these common signs of autumn in the plant kingdom:

Signs of fall in the plant kingdom: Seasonal Changes in Plant Life:

• Leaves Change Color: In the autumn, the leaves of deciduous trees change color and fall to the ground. Only evergreen trees retain their green color.
• The Landscape Changes Color: Autumn colors, such as vibrant reds, oranges, yellows, and browns, dot the landscape, making the world look gorgeous.
• Deciduous Trees Shed Their Leaves (Leaf Drop): In autumn, as days grow shorter and temperatures drop, leaves change color and fall to the ground.
• Fall Leaves Cover the Ground: The falling autumn leaves create a vibrant carpet of colors on the ground in forests, woods, and neighborhoods, making for picturesque landscapes.
• Summer Flowers, Plants, and Produce Go Dormant or Die: Flowers and plants slow their energy production, wilt, and lose their petals and leaves in response to decreased sunlight and colder temperatures.
  • Some plants, flowers, and produce go dormant, while others die in response to colder fall air.
• Grass Slows Its Growth: Grass grows more slowly in the fall.

New Garden and Plant Life That Bursts Forth, Blooms, or Ripens in Autumn:

• Fall Harvest: In autumn, seasonal produce and other treats, such as nuts and seeds, are ripe and ready to pick.
• Seasonal Produce, Fruits, and Berries Ripen: Fall vegetables, fruits, and other produce (such as pumpkins, apples, winter squash, almonds, walnuts, and pecans) are ready for home gardeners and farmers to harvest, while other food sources go dormant.
  • Berries that ripen in the fall, such as blackberries, wild raspberries, and elderberries, are ripe and ready for picking.
• Seeds and Nuts Ripen: In the autumn, Acorns, pinecones, Sycamore “helicopters,” and other nuts and seeds ripen and fall to the ground.
  • Some plants, like coneflowers and milkweed, produce spiky seed pods that burst open in the fall, scattering seeds to ensure their propagation in the next growing season.
• Mushrooms and Fungi Grow: In the fall, many varieties of fungi emerge from the forest floor, and mushrooms appear everywhere.
• Fall Flowers and Plants Bloom: Autumn flowers such as Asters, Marguerites, Goldenrods, Chrysanthemums, and spider lilies bloom in the fall.
  • Flowering Ivy can also be spotted growing in the autumn.

Wildlife Signs that Autumn is Approaching: Birds, Animals, Insects, ETC. in the Fall:

One of the most spectacular signs of fall is bird migration. As the days grow shorter and temperatures drop, many bird species begin their long journeys south to escape the harsh winter. Birdwatchers eagerly await this seasonal event, making it an ideal time to spot a diverse range of migratory species.

Another common sign of autumn in the animal kingdom is the frenzied nut-gathering behavior of squirrels. In the fall, squirrels scurry around the forest, parks, and even your backyard, collecting and burying acorns, walnuts, and other nuts. This behavior, known as caching, helps them prepare for the winter when food is scarce. So, watch for squirrels busily stashing away their winter supplies because it is a sure sign of fall.

Likewise, the remaining signs of fall in the animal kingdom, such as the bird kingdom, below, help illustrate the intricate ways wildlife responds to the changing seasons. Observing these behaviors and interactions can deepen your connection with the natural world and increase your appreciation for the beauty of the changing seasons.

Signs of fall in the animal kingdom:

• Animals Grow Thicker Coats: Pets and local wildlife begin to shed less and grow thicker fur to prepare for the cold winter months.
  • By the end of the fall, animals in colder climates often have an entirely different winter coat than they do in the warmer summer months.
• Birds and Animals Gather and Store Food: Rodents such as Squirrels, small birds, and many other animals go on a gathering frenzy as they collect, gather, build, and stash their winter food stores.
• Mammals Prepare for Hibernation: Mammals that hibernate for the winter, such as bears and hedgehogs, are often seen eating to build fat stores for hibernation.
  • In the fall, bears enter a phase known as hyperphagia, during which they consume massive amounts of food to build up fat reserves. This increased bear activity can lead to more frequent bear sightings, especially near food sources such as berry patches and salmon streams.
• Animals Mate: Bats, deer, elk, and wild boar seek mates and engage in mating behaviors. (In the late summer and early fall, many animals engage in courtship rituals by calling to attract mates or battling with other eligible suitors.)
  • Bats sing for their mates around the entrances to caves and tunnels.
  • You can hear the distinctive calls of frogs and toads around bodies of water, such as ponds and wetlands.
  • You might hear the bugling of the bull elk looking for a mate.
  • Meanwhile, male deer and wild boar fight other males for a mate. Fall is the mating season for deer, known as the rut. During this time, male deer, or bucks, become more aggressive as they compete for females’ attention. So, you might hear the echoing sounds of antlers clashing as they battle for dominance. 

Signs of Fall in the Bird Kingdom, Invertebrates, Reptiles, Arachnids, and Other Wildlife:

• Migrating Birds: Flocks of birds migrate south for the winter (geese, swallows, hawks, hummingbirds, etc.)
  • Look for V-shaped formations of geese, flocks of warblers, and other species in flight as they make their way to warmer climates.
• Migration of butterflies: Some butterflies migrate, such as the Monarch Butterfly, which flies to warmer climates where they can survive until spring.
• Some Invertebrates and Reptiles Prepare for Hibernation: During the cooler months, particular species of butterflies (such as the Mourning Cloak and the Question Mark Butterfly), ladybugs, and other invertebrates and reptiles seek shelter to hibernate.
  • Other butterflies don’t migrate or hibernate. Instead, they lay eggs or leave behind pupae (chrysalises) before dying, which hatch when temperatures warm up in spring.
• Spiderwebs Appear Everywhere: Orb-weaving spiders return to work weaving their beautiful, round spiderweb masterpieces in the autumn.
  • Fall is when orb-weaving spiders are more active, making it more likely for you to see intricate spiderwebs glistening with dew in the early morning.

Other Signs that Fall is on Its Way:

Except for warmer climates near the equator, the arrival of fall means it’s time to slip into your coziest sweaters and scarves, dust off your favorite boots, sip on a pumpkin spice latte, and bake pumpkin bread. Here are a few more random signs that fall has arrived:

Random signs of fall:

• Lower Energy Bill: Your energy bill is lower because you need the air conditioner less often.
• People Doing Yardwork: Neighbors and landscapers can be spotted raking and cleaning leaves, pruning plants, and trees in preparation for winter.
• Football Games: Football season begins.
• Fewer People Outside: Fewer people are on beaches and at pools.
• Autumn Decor: Fall decor begins to appear.
• Halloween Decorations: People start decorating for Halloween in the fall, and various spooky and fun Halloween decorations pop up all over the neighborhood.
  • Halloween costumes and decorations are available in stores.
• People Wearing More Layers of Clothing: Lower temperatures and colder mornings than afternoons make people layer up, putting on more clothes in the morning and peeling layers off on warmer autumn days.
• Boot, Flannel, and Cashmere Season Begins: Yay! Need I say anything more?

Frequently Asked Questions about the Fall or Autumn:

Here are a few more frequently asked questions (FAQs) that people often have about the fall (autumn) season. I’m sharing them here to help you answer the many questions children usually ask in the fall about the changes they notice around them. Remember, when helping our children find the answers they seek, it’s best to help them discover them on their own.

In other words, when they start asking questions like those below, answer them with follow-up questions that encourage them to think about the answer independently. If you are unsure of how to do that, repeat the question they asked you with a tone that enables them to consider what the answer might be. Then, continue guiding them to the solution without revealing the answer. This form of instruction is an art; teachers are everyday heroes in a child’s world.

What months are considered the fall season?

The meteorological season of fall, or autumn, typically occurs in September, October, and November. However, some cultures celebrate the beginning of fall at the first harvest in August. These same cultures view the fall equinox as the season’s midpoint, while others consider it the first day of fall.

Is Autumn and Fall the Same Thing?

Yes, “autumn” and “fall” are two different words for the same season, so you’ll see them used interchangeably throughout this guide. In many parts of the world, especially in North America, the season that comes after summer and before winter is commonly called “fall or autumn.”

However, in many other English-speaking regions, including the United Kingdom, “autumn” is preferred. Both words describe the year’s third season, when the weather cools, nights grow longer, and the leaves on deciduous trees change color and fall to the ground. In some areas, this season was also traditionally called “harvest.” 

What is the season of fall known for?

As mentioned earlier, one of the most iconic signs of fall is the transformation of the foliage as leaves change color. In the autumn, the lush greens of summer give way to a stunning display of reds, oranges, and yellows. Once the fall colors paint the sky with their crimson hues, it’s only a matter of time before the trees shed their vibrant autumn leaves and fall.

Soon, deciduous trees start shedding their leaves, creating a golden carpet of lush autumn foliage wherever they stand. Until someone cleans up these autumn leaves–which is yet another sign of the season. Please scroll down for a more detailed explanation of the numerous changes that occur in the fall. You might also enjoy these Outdoor Learning and Nature Activities for Kids.

Why do leaves change color in the fall or Autumn?

Leaves contain a substance called chlorophyll, which allows trees to make their own food from sunlight and gives them their vibrant green color. As the days grow shorter in the fall and each night becomes longer–especially after the Autumnal Equinox–chlorophyll production slows down and eventually stops.

Soon, any remaining chlorophyll in deciduous trees and bushes breaks down, allowing the naturally occurring carotenoids and anthocyanins in the leaves to show their colors. The landscape fills with bright reds, oranges, and yellows, making autumn a visually stunning season.

In other words, these fall colors have always been present within the leaves but were hidden by the pigment chlorophyll and its green hue. Once chlorophyll production declines and stops, these colors can emerge and shine through.
