Weather in Santorini
Santorini is a volcanic archipelago in the southern Aegean Sea. The islands enjoy a stunning climate and temperatures remain warm for most of the year.
Santorini has two distinct seasons, summer and winter. Summer is mostly hot, sunny and dry with constant high temperatures and mild sea water. Things begin to cool off in winter and rainfall increases, which means you’ll need to pack an umbrella for your visit.
The best time to go to Santorini for the best weather is during the summer, which runs from March to October. March has the coolest weather during this time, with an average high of just 16°C. August is the warmest month with an average temperature of 27°C.
For cooler temperatures, the winter season is the best time to visit Santorini. The weather has cooled to more comfortable levels and you’ll still get to enjoy lots of Mediterranean sunshine.
Rainfall is at its heaviest in December and January. Both months receive around 70mm of rainfall over 11 wet days.
