Best Time to Visit Santorini

Month-by-month in short

April–May: mild, spring flowers, lower rates. June: excellent swimming and reliable sun. July–August: hottest and busiest; book tours early. September–October: warm water, grape harvest vibes, softer light. November–March: quiet, some hotels closed, great for walkers who accept wind.

Best time for tours and sunsets

For private bus tours and helicopter slots, May–June and September balance weather and availability. Sunset views are year-round; summer haze can soften distant volcano shots.
