Is It Autumn Yet?

A patch of Maximilian sunflower is a reminder of summer

I climbed the switchback trail up to the ridge at Southwest Nature Preserve yesterday, and it felt a little different. The high temperature was still in the 90s and there were no clouds to deflect a little of the sun’s radiant warmth, but there was a barely perceptible difference. Through much of the summer, the humid air has wrapped us in a blanket of heat, but not so much today. The slight breeze that previously could not penetrate that sticky blanket was refreshing this time. I wondered if this was the first hint of autumn.

The orange tones of poison ivy leaves

Autumn has a distinct personality. The sensory world of autumn is one of cool breezes, even a little chill, and in the fields there is the faint smell of ripening and even decay as leaves come to the end of their usefulness and fall from trees and shrubs. It’s a good sort of decay; it’s the soil-creating process, the vintage bouquet of oak and ash leaves, with notes of hackberry and possumhaw. I look forward to bright, cool days in woods and prairies and the chance to smell that legacy of what grew in the summer.

Where I live, autumn’s sensory world includes leaves turning color, gradually and in varying degrees. There are the brilliant colors of sumac (one species of which is “flameleaf sumac,” which gives a clue as to its contribution to autumn color) as well as the varied colors of poison ivy. The oak leaves sometimes become very colorful, but only sometimes. And then when the leaves have fallen, we get a look into woodlands where before there were curtains of green. On through the coming winter, sunny days flood the ground around the tree trunks with light.

The quality of that light is an important part of autumn’s personality. Our part of the earth is tilting away from the sun, and light reaches us from a slanting angle. In a trick of physics, it is more golden, with an end-of-the-day feel, a suggestion of sunset all day long. In a verse that introduces autumn in a forthcoming book, I said, “Things come to an end / Be still in the golden autumn light.” The sense of the year coming to an end suggests a time for contemplation, to “consider how to make a good end of the year / With affection and acceptance.”

Is it autumn yet? One way of defining the seasons says that autumn begins with the first of September. The other way, based on the position of the sun, says that autumn begins when the shortening days and lengthening nights are of equal lengths. The equinox, typically on September 23, marks the beginning of autumn.

That day is less than two weeks away. I look forward to that day and to every little sign that autumn is coming.
