Key facts about Santorini’s climate

The island of Thera enjoys a classic Mediterranean climate characterized by hot, dry summers and mild, wet winters. This climate is influenced by its geographic location in the Aegean Sea, which results in relatively stable weather patterns throughout the year.

June to August

This is summertime in Greece. During these months, Santorini experiences peak tourist season due to its warm temperatures and charming climate. Average temperatures range from 25°C to 35°C (77°F to 95°F), making it more attractive for beach activities and exploring the island’s attractions.

The mid-season offers a balance between favorable weather and fewer crowds. Temperatures during these months are pleasant, ranging from 18°C to 25°C (64°F to 77°F), making it an ideal time for sightseeing and outdoor activities without the intense heat of summer.
