Life on the island soon develops a daily rhythm. Morning is pleasant, with cool air and sweet smells, and the boys are able to play happily. By afternoon, though, the sun becomes oppressively hot, and some of the boys nap, although they are often troubled by bizarre images that seem to flicker over the water. Piggy dismisses these images as mirages caused by sunlight striking the water. Evening brings cooler temperatures again, but darkness falls quickly, and nighttime is frightening and difficult.
