What’s the weather like in Santorini in October?

Santorini’s an archipelago of five volcanic islands in the southern Aegean, some 200km southeast of mainland Greece. If you’re going in October you’ll have cooler temperatures compared to the height of summer, although the weather’s still warm and you’ll get lots of sunshine.

Two seasons

Santorini’s the furthest south of the Cyclades islands, and has hot Mediterranean weather that’s more like two seasons rather than four. October’s the last month of a warm and dry summer that starts in April, with things getting cooler and wetter in winter. Santorini’s a bit cooler than other Mediterranean islands, so it’s ideal if you prefer lower temperatures. You’ll be kept cool by the sea and breezes if you’re on the coast.


The average high’s 23ºC in October, so it’s still nice and warm, although you should bring a warmer jumper for the evenings as things cool to 16ºC at night. The sea’s still inviting at 23ºC, while humidity’s low. There’s 38mm of rain over four days, and you can expect 11 hours of daylight with seven hours of sunshine at a moderate UV level. The sun goes down just after 7pm at the start of October, with the end of daylight saving bringing this forward to just before 5.30pm towards the end of the month.

Things to Do

As Santorini’s volcanic, it has black sand beaches as well as Akrotiri’s Red Beach. The weather’s ideal for sightseeing in October, so visit ancient Thira with its Roman, Hellenistic and Byzantine ruins. Take in a lovely sunset as the evening draws in then head out for a taste of Santorini’s buzzing nightlife.
