Santorini island, like the rest of the Cycladic islands in the Aegean Sea, bears a typical Mediterranean climate with warm summers and prolonged sunshine days on the largest part of the year, making it an ideal destination for summer holidays.

Hot summer weather starts to make its appearance in Santorini in June, when the sun shines at its brightest and one can enjoy their day by the beach, take a swim at the blue waters or just relax and absorb the warmth of the sun. The same applies for the rest of the months until September, with July and August being the hottest of all the summer months, with temperatures reaching high levels. This hot weather attracts many travelers and this period is considered a high season for the island. We could say that, during these months, Santorini bursts with life!

However, indications of warm weather start from the second half of April, during the Spring season, when there are moderate temperatures and the sea starts warming up, which makes it possible to have a swim, but not guaranteed. It is easier to move around the island though, compared to the next months with the high number of guests, and admire its tremendous landscape and its unique volcanic beauty.

Generally, the warm climate with the continuous sunshine and the high temperatures during summer, in combination with the capturing views, make Santorini one of the most visited islands of Greece!
