Crete's weather is influenced by two climatic zones, the Mediterranean and the North African. Most of the island falls under the Mediterranean climate and as such is primarily temperate. The atmosphere can be quite humid, depending on the proximity to the sea, while winters are fairly mild. Snowfall is common on the mountains between November and May, but rare at the low lying areas - especially near the coast when it only stays on the ground for a few minutes/hours During the summer, average temperatures reach the high 20s-low 30s (Celsius), with maxima touching the upper 30s to mid 40s. The south coast, including the Messara plain and Asterousia Mountains, falls in the North African climatic zone, and thus enjoys significantly more sunny days and high temperatures throughout the year. In southern Crete date palms bear fruit and swallows remain year-long, without migrating to Africa.
