Alonissos Weather

The weather in Alonissos is the same with the one of the other northern Sporades (Skiathos and Skopelos), a climate characterized by mild winters with frequent rainfalls and warm summers with quite high temperatures, cooling thanks to the blowing “meltemia” (north winds) during late July and early  August.
