Santorini’s weather makes it a suitable destination year round. The island doesn’t receive heavy rainfall at any point during the year however December and January are typically the wettest months. The weather throughout autumn and winter is slightly more unpredictable than summer, but the skies generally remain blue and the weather remains mild. Winter sees mean temperatures of about 10 ºC to 12 ºC, with night time temperatures pushing to zero so a jacket is a necessity if visiting in this period.
