I am going to say it, even though there was snow ten days ago. This is the opening of Dandelion Wine, my summer book:

It was a quiet morning, the town covered over in darkness and at ease in bed. Summer gathered in the weather, the wind had the proper touch, the breathing of the world was long and warm and slow. You had only to rise, lean from your window, and know that this indeed was the first real time of freedom and living, this was the first morning of summer.
