Santorini weather at a glance

• Santorini (Cyclades) follows a Mediterranean pattern: **summers (Jun–Aug) are hot and very dry**.
• In July–August, the Meltemi winds can make it feel less hot, but stronger wind can affect **boat tours and perceived chill** at night.
• Spring (Apr–May) and autumn (Sep–Oct) are often ideal for walking, views, and outdoor dining.
• Winter (Dec–Feb) is mild but wetter; wind and rain can feel chilly, and seasonal operations may be quieter.
• Comfort depends on wind exposure (caldera cliffs), sunset cooling, and sea activities—not just temperature.
