With its cliffside villages, brilliant blue domes, and iconic sunsets, Santorini is one of the most sought-after destinations in Europe. While the island is beautiful year-round, the experience can vary greatly depending on when you visit. If you are looking for the perfect balance of good weather, smaller crowds, and open attractions, the best time to visit Santorini, Greece is mid to late September.
