Autumn is the in-between season. It’s the transition between summer and winter. A time when, by and large, the growing season ends, as the days become shorter and the temperatures drop.
When does Autumn begin?
Meteorologists use a simple method of dividing each season into a three month period: Spring is Mar-Apr-May; summer is Jun-Jul-Aug; Autumn is therefore Sep-Oct-Nov, and Winter is Dec-Jan-Feb.
Astronomers, on the other hand, use Earth’s position relative to the Sun to define the seasons. Autumn begins at the Equinox (around 21 Sep) when days and nights are of equal length. It continues until the Winter Solstice (around 21 Dec) when daylight hours are at their shortest.
Another way to define when Autumn begins is to simply note any signs of change in plants and in animal (including human) behaviours. These ‘signs of Autumn’ feel like a more natural way to determine the coming and going of the season.
Signs of Autumn 1: harvesting crops
One of the most iconic images of autumn in the UK is that of neatly-balled hay bales lying on golden stubble in low gilded sunshine.

Signs of Autumn 2: turning leaves
As the days get shorter and the sunlight decreases, many trees don’t have enough light to photosynthesise. They stop producing (green) chlorophyll and their leaves start to change colour.

Signs of Autumn 3: fruits and seeds
Sycamore seed ‘helicopters’, acorns, blackberries and other wild fruits begin to ripen and disperse.

What are your signs of Autumn?
I’m sure you’ll have your own favourite signs that hint at the beginning of Autumn. Is it the appearance of ripe sloes in the hedgerows? The arrival of redwings? The first acorn to fall? The first blackberry?
Whatever signs of Autumn are important to you, they are not dictated by a set date on a meteorologist’s or astronomer’s calendar: they reflect some, perhaps cherished, change in the natural world that holds a particular personal significance. Enjoy!
