The best time to visit Santorini depends on what you’re looking for in your trip — whether it’s pleasant weather, fewer crowds, lower costs, or vibrant energy. Let’s break it down based on weather, tourist traffic, and overall experience.
Weather
Santorini has a Mediterranean climate with hot, dry summers and mild, wet winters.
- Spring (April to May): Temperatures range from 18°C to 27°C (64°F to 81°F). April can be a bit cooler with occasional rain, so make sure to pack some warmer clothes too, but by May and June, it’s warm and sunny, perfect for exploring without the scorching heat. The sea is starting to warm up for swimming by late May.
- Summer (June to August): Peak season brings highs of 30°C to 35°C (86°F to 95°F). It’s hot and dry, ideal for beach days and swimming, but the intense sun can make midday sightseeing uncomfortable, especially when viewing those blue-domed churches in Oia against the bright white buildings or hiking the many trails.
- Fall (September to October): Temperatures cool slightly to 22°C to 28°C (72°F to 82°F). September still feels summery, with warm seas, while October brings a crispness and occasional rainfall. The light in fall is softer, making photography of Santorini’s landscapes and architecture stunning.
- Winter (November to March): Temps drop to 10°C to 15°C (50°F to 59°F), with more rain and wind. The island is quiet, and you can still enjoy the views if you don’t mind cooler weather.
Crowds
Santorini is a hugely popular destination, so crowd levels vary significantly.
- Peak Season (June to August): The island is packed, especially in July and August. Popular spots like Oia can feel overcrowded, with long waits for photos. Prices for accommodations and flights are at their highest as well.
- Shoulder Seasons (April to May, September to October): These months strike a balance. April and October are quieter, with fewer tourists, while May and September are busier but not as chaotic as summer.
- Low Season (November to March): The island is very quiet, with many hotels and restaurants closed until next season. If you’re fine with limited options, you can find great deals and experience Santorini’s charm without the crowds.
Overall Experience
- For Ideal Weather and Balance: May and September are often considered the sweet spots. The weather is warm, the sea is swimmable, and the crowds are manageable. You’ll get to enjoy those blue-domed churches in Oia without elbowing through throngs of tourists, and the light is perfect for capturing the contrast against the whitewashed buildings. Plus, businesses are fully operational.
- For Vibrant Energy: July and August are for those who thrive in a lively atmosphere. The island buzzes with energy — think bustling cafes, sunset crowds, and a festive vibe. But be prepared for the heat and the challenge of finding a peaceful spot for a romantic evening.
