The First Signs of Autumn: Watching the Year Turn

Autumn doesn't arrive on one particular day. Although we have dates in the calendar that tell us when the season officially begins, the natural world starts changing long before we reach them. By late August, there are already signs that summer is beginning to fade: the evenings are getting shorter, some leaves are starting to change, berries are ripening in the hedgerows and the mornings can feel noticeably cooler.

These changes can be easy to miss, especially when we're still enjoying warm days and thinking of summer as very much here. But if you slow down and pay attention, the landscape starts to tell you that the year is moving on. The first signs of autumn are not usually dramatic; they appear gradually, in the plants, animals, light and weather around us.

For much of history, noticing these changes was more than simply enjoying the seasons. People depended on the natural world for food and shelter, so knowing when fruits were ready to gather, when crops were approaching harvest, when birds were beginning to migrate and when colder weather was on its way could be important knowledge. Over time, these observations became part of seasonal customs, weather lore and folklore.

Today, most of us don't need to watch the hedgerows or the sky to know that autumn is coming. We have calendars, weather forecasts, supermarkets and heating to tell us what season we're in. Even so, there is something lovely about learning to recognise those older signs for ourselves and paying attention to the small changes happening around us.

So, before autumn is properly here, let's take a look at some of the first signs that the year is beginning to turn.

The Light Begins to Change

One of the earliest signs that summer is coming to an end is the changing amount of daylight. After the summer solstice in June, the days gradually begin to shorten, although the difference isn't always easy to notice at first. By the end of August, however, the evenings are noticeably darker than they were in June and July, and by September the change is much more obvious.

This happens because of the tilt of the Earth as it travels around the Sun. During summer in the Northern Hemisphere, our part of the Earth is tilted towards the Sun, giving us longer days and shorter nights. As the year moves on, this changes and the days gradually become shorter until we reach the winter solstice in December.

The autumn equinox usually falls around 22 or 23 September in the UK. It marks the point when the Sun crosses the celestial equator, and day and night are roughly equal in length. After this, the nights continue to become longer as we move further into autumn and towards winter.

For us, this might simply mean reaching for the lights a little earlier in the evening, but for people in the past, the changing daylight had a much bigger effect on everyday life. Without electric lighting, there was only so much work that could be done once the sun had gone down. The length of the day affected when people could work outside, travel, gather food and carry out many of the jobs that kept a household running.

The changing light was therefore an important part of the seasonal calendar. Even before the first autumn leaves appeared or the hedgerows were full of ripe fruit, the shortening days were already showing that the year was moving towards its colder, darker months.

The Hedgerows Begin to Ripen

If the changing light is one of the first signs of autumn above us, the hedgerows are one of the easiest places to see the season changing around us. By late August, the flowers and fresh green growth of early summer are beginning to give way to ripening fruits, with blackberries, elderberries, hawthorn berries and rosehips appearing in different parts of the countryside. A little later, the darker sloes of the blackthorn begin to ripen too, although exactly when each fruit appears can vary depending on the plant, weather and where you live.

For people in the past, this seasonal change was much more than something to enjoy on a country walk. Hedgerows provided a useful source of food at a time when people relied far more heavily on what could be grown, gathered and preserved locally. Wild berries could be eaten fresh or made into jams, jellies, syrups and other preserves, while fruits such as sloes could be kept and used later in the year. Gathering from the hedgerows was part of the seasonal rhythm of rural life, and knowing when different fruits were ready was useful knowledge passed between generations.

The hedgerow can therefore be thought of as a kind of natural calendar. The arrival of ripe blackberries tells us that summer is moving towards autumn, while the later appearance of sloes and rosehips points further into the season. We don't need a date on a calendar to know that the year is changing when the landscape is beginning to offer up its autumn harvest.

Many of these plants also have their own folklore and traditions, which have developed over generations and vary from place to place. Elder, hawthorn, blackthorn and rowan are all good examples of plants with stories attached to them, and they are subjects we'll return to elsewhere in the Archives.

For now, it is enough to notice what the hedgerows are telling us. They are still full of life, but the focus is beginning to shift from flowering and growing to ripening and gathering.

The First Changes in the Landscape

The hedgerows aren't the only part of the countryside that begins to change as summer comes to an end. Look a little closer and you'll start to notice smaller changes happening across the landscape too. The first leaves begin to turn, mornings become cooler, and the grass and plants can stay wet with dew for longer.

The leaves are probably the most familiar sign. Some trees begin to change colour towards the end of summer, although the timing varies between species and from one year to the next. As the days shorten, trees begin to prepare for winter by breaking down the green chlorophyll in their leaves. Once the green fades, other colours that were already present in the leaves become easier to see, giving us the yellows, oranges and reds that we associate with autumn.

The change doesn't happen everywhere at once. You might find one tree still completely green while another nearby has already started to turn, and a sheltered garden can look quite different from an exposed field. Weather and local conditions can affect when the changes begin, so the landscape doesn't follow an exact timetable.

The mornings begin to change too. As the nights become cooler, dew can become more noticeable on grass, plants and spider webs. In suitable conditions, mist can settle across fields and gardens in the early morning, making familiar places look softer and more distant than they did during the brighter days of summer. Mist and fog have long appeared in folklore and stories, but they also have a simple natural explanation. When moist air cools, water vapour can condense into tiny droplets, creating the mist we see close to the ground.

This is also a good time of year to start noticing spider webs. Spiders are around throughout the warmer months, but their webs can suddenly become much easier to spot when the cooler mornings cover them in dew. A web that would normally blend into the grass or hedge is picked out by hundreds of tiny droplets, making something that was already there much easier for us to see.

These changes are small, but together they show that the landscape is beginning to prepare for the colder months. Some plants are slowing down, trees are preparing to lose their leaves and the cooler mornings are changing the way the countryside looks and feels.

The Signs in the Sky

The changing season can also be seen above us. Towards the end of summer, some birds begin to gather in preparation for migration, while others start to arrive as the weather becomes cooler. In Britain, the departure of swallows and house martins is one of the more familiar signs that summer is coming to an end.

Migration is a natural part of the yearly cycle for many birds. Several things influence when birds migrate, including changes in daylight, temperature and the availability of food. As summer ends and insects become less plentiful, birds that rely on them may begin their journeys to places where food will be easier to find.

Some birds travel enormous distances during these journeys, crossing countries and even continents before returning again the following year. Their movements are one of the clearest examples of how closely animals respond to changes in the seasons.

People have watched birds for a very long time, and their arrival and departure became useful signs of the changing year. Before modern calendars and weather forecasts, observing birds and other animals could provide clues about what was happening in the natural world. These observations also found their way into traditional sayings and weather lore.

Swallows in particular became closely associated with the warmer months because their arrival in spring and departure later in the year were so noticeable. Their movements gave people another way to recognise that the seasons were changing.

The birds are therefore following their own seasonal calendar, just as the plants and trees are. While we might notice autumn first in the shortening evenings or the changing leaves, the movement of birds reminds us that the change is happening throughout the natural world.

The Harvest Is More Than a Symbol

When we think about autumn today, harvest is often treated as a symbol of the season. We see pumpkins, sheaves of wheat, apples and baskets of produce used in autumn decorations, but for much of history, harvest was not simply a seasonal theme. It was a very important part of everyday life.

For people who depended on farming and growing their own food, there was a limited window in which crops could be gathered before the weather became too cold or wet. The timing of the harvest mattered, and a poor harvest could have serious consequences for the months ahead. Once crops were ready, there was a lot of work to be done, often involving whole communities working together to bring them in.

The food gathered during this time also needed to last. Grain could be stored, fruit could be preserved, vegetables could be kept for later and meat could be prepared in ways that allowed it to be eaten through the winter. The abundance of late summer and early autumn therefore had a practical purpose: it helped prepare households for a season when fresh food would be much harder to find.

This is why harvest became associated with both hard work and celebration. Once the most important work was finished, communities could come together to mark what had been gathered and give thanks for the food that would see them through the colder months. Harvest festivals developed in different forms and at different times, with traditions varying between regions and communities.

Many of the customs we now associate with harvest have changed over time, and some of the familiar imagery is much more recent than people might expect. Even so, the basic idea has remained the same. Autumn is a time of gathering, storing and preparing for what comes next.

The changing light, ripening hedgerows, turning leaves and migrating birds all point towards the same thing: the growing season is coming to an end and the time for gathering and preparing is beginning. The traditions that grew around harvest are another part of that story, and they are worth exploring in their own right.

Learning to Notice

Most of us no longer need to watch the natural world to know when the seasons are changing. We have calendars to tell us when autumn begins, weather forecasts to tell us what the week ahead might bring and shops filled with whatever food we need throughout the year. The seasonal signs that were once important pieces of everyday knowledge are no longer something we have to rely on.

But they are still there.

The light changes, the hedgerows ripen, leaves begin to turn and birds start preparing for their journeys. These things have been happening year after year for far longer than we have had calendars or weather forecasts, and people have been watching them for generations. Their observations became part of the knowledge, traditions and folklore that have been passed down through the seasons.

We don't need to depend on those signs in the way people once did, but learning to notice them can give us a better sense of where we are in the year. Autumn is not simply a date on the calendar or a collection of familiar colours and decorations. It is a gradual change happening all around us, and sometimes the best way to experience it is simply to pay attention.
