Weather and climate in Crete, Greece are the mildest in Europe
The weather and the climate in Crete are unique. Crete straddles two climatic zones, the Mediterranean and the North African, mainly falling within the former. As such, the climate in Crete is primarily temperate.
The atmosphere can be quite humid, depending on the proximity to the sea.
The winter weather in Crete is fairly mild. Snow fall is practically unknown to the plains, but quite frequent in the mountains.
During summer, the weather in Crete is hotter, but not much: average temperatures are in the high 20's-low 30's (Celsius). The exception can be the south coast, including the Messara plain and Asterousia mountains, which fall in the North African climatic zone and thus enjoys significantly more sunny days and high temperatures during the summer.
Regarding the weather and climate, the best time to visit Crete is during spring or autumn.
