With its cliffside villages, brilliant blue domes and iconic sunsets, Santorini is one of the most sought-after destinations in Europe. But, while the island is beautiful year-round, the experience can vary greatly depending on when you visit. From quiet winter escapes to sun-soaked summer adventures, here’s how to plan your ideal trip.

This guide breaks down the best time to visit Santorini, Greece by season — with average temperatures, crowd levels and can’t-miss experiences to help you make the most of your Aegean getaway.

Spring: March to May

Best for: Mild Weather & Blooming Landscapes

Average temperatures: 55°F to 70°F (13°C to 21°C)

Spring in Santorini is peaceful and picturesque. Wildflowers bloom across the caldera, temperatures rise steadily and the island begins to wake up from its winter lull. It's a fantastic time to explore villages and hike the scenic trails before the summer crowds arrive.

Key Events & Activities:

• Fira to Oia Hike: Enjoy the island’s most famous walking trail in comfortable weather and without peak-season foot traffic.
• Archaeological Sites: Visit Akrotiri and Ancient Thera while the climate is ideal for sightseeing.
• Greek Easter Celebrations: Depending on the calendar, Easter festivities (usually in April) bring cultural traditions and fireworks to Pyrgos village.
• Winery Tours: Vineyards reopen for tastings of local varietals like Assyrtiko as the vines begin to bud.

Spring is perfect for travelers who want mild temperatures, active exploration and a quieter atmosphere with lower hotel rates.

Summer: June to August

Best for: Sunbathing, Swimming & Vibrant Island Life

Average temperatures: 75°F to 85°F (24°C to 29°C)

Summer is Santorini’s high season — and it delivers big. The days are long and sunny, the beaches are buzzing and every restaurant terrace is open for business. But, with the beauty comes crowds and higher prices, so make sure to plan ahead.

Key Events & Activities:

• Red & Perissa Beaches: Swim and sunbathe on the island’s unique volcanic beaches with their black and red sands.
• Boat Excursions: Sail around the caldera, stop at Nea Kameni for a hike or swim in the island’s hot springs.
• Santorini Jazz Festival (July): Enjoy live music in Kamari, featuring both Greek and international acts.
• Oia Sunsets: Get there early — this is one of the most photographed sunsets in the world, and it draws a crowd every night.

If you don’t mind the heat and want to experience Santorini in full swing, summer offers all the iconic views and vibrant energy the island is known for.

Autumn: September to November

Best for: Fewer Crowds & Warm Weather

Average temperatures: 65°F to 80°F (18°C to 27°C)

Autumn may be the best time to visit Santorini, Greece for most travelers. The sea is still warm from summer, the weather is comfortable and the crowds begin to thin — especially by late September. Prices also start to dip, making it a great time for value-focused trips.

Key Events & Activities:

• Harvest Season: Tour wineries during grape harvest and sample fresh vintages straight from the barrel.
• Photography: The softer autumn light makes for even more stunning photos across Fira, Imerovigli and Oia.
• Island Hopping: Take a ferry or guided boat tour to nearby islands like Ios or Naxos for a relaxed day trip.
• Santorini Experience (early October): This sporting event combines running and open-water swimming with spectacular views and a festive vibe.

Autumn offers the best of both worlds: summer-like warmth with less hustle, making it ideal for couples, solo travelers and photographers.

Winter: December to February

Best for: Quiet Getaways & Budget Travel

Average temperatures: 50°F to 60°F (10°C to 16°C)

Winter is the quietest season on Santorini. Many hotels and restaurants close for the season, but the island’s natural beauty remains. While you won’t be swimming or sailing, this is a serene time for slow travel, writing retreats or cozy village strolls.

Key Events & Activities:

• Fira Old Town: Walk through narrow alleys and take in the caldera views without the crowds.
• Local Life: Enjoy a more authentic experience in villages like Megalochori or Pyrgos, where life moves at a relaxed pace.
• Photography: The whitewashed architecture pops against moody skies, offering a different — but equally stunning — take on Santorini.

Though quiet, winter in Santorini is peaceful and atmospheric, great for those who prefer culture over beach time.
