Gene Wolfe, “The Island of Doctor Death and Other Stories” (1970)

Winter comes to water as well as land, though there are no leaves to fall. The waves that were a bright, hard blue yesterday under a fading sky today are green, opaque, and cold. If you are a boy not wanted in the house you walk the beach for hours, feeling the winter that has come in the night; sand blowing across your shoes, spray wetting the legs of your corduroys.
