Santorini's shoulder season spans April–May and September–October, offering the best balance of good weather, manageable crowds, and significantly lower prices. May and October are the two stand-out months — warm, beautiful, and half the price of July–August.

Best Shoulder Season Activities
Wine harvest (September–early October): Join a grape harvest at Argyros or Hatzidakis winery. Hiking: The Fira-to-Oia caldera trail is perfect in spring and autumn (not the 35°C summer heat). Photography: The autumn golden-hour light is extraordinary. Fewer people in frame.
