The best time to visit Santorini

Breathtaking Santorini village of Oia with iconic Greek architecture and flags. Sweet spot: May · June · September
In short

The best time to visit Santorini is late spring (May and early June) and early autumn (September to early October), when the weather is warm and sunny but the summer crowds have thinned. July and August are peak season—hot, busy and expensive, with Oia's sunset spots packed shoulder to shoulder. Winter is the low season: cool, quiet and windy, with many businesses closed, though the island is at its calmest and most affordable.

Season by season

When to go, and what to expect

Spring (Mar–May)

Weather: Cool and breezy early on, warming to mild and pleasant by May; wildflowers and green landscapes.
Crowds: Quiet in March and April, building steadily through May.

Ideal for hiking, sightseeing and photography without the summer heat or crush—May is a sweet spot.

Summer (Jun–Aug)

Weather: Hot, dry and reliably sunny; strong meltemi winds can pick up, especially in July and August.
Crowds: Peak season—very busy, with Oia's sunset viewpoints extremely crowded.

Best for beach days and nightlife if you don't mind heat and crowds; book everything well ahead.

Autumn (Sep–Nov)

Weather: Warm and sunny in September, cooling into October; the sea stays warm for swimming.
Crowds: Thinning through September and October; noticeably calmer than summer.

Arguably the best all-round time—warm weather, swimmable sea and fewer people. September is a top pick.

Winter (Dec–Feb)

Weather: Cool, wet and windy; the caldera can be dramatic but conditions are changeable.
Crowds: Very quiet; many hotels, restaurants and shops in Oia close for the season.

Only for travellers wanting solitude and low prices; expect limited services and few open venues.

Frequently asked

What is the cheapest and quietest time to visit Santorini?

Winter (roughly November to March) is the low season, with the lowest prices and fewest visitors—but also cooler, windier weather and many closed businesses in Oia and Fira.

Is September a good time to visit Santorini?

Yes. September offers warm, sunny days, a sea that's still warm for swimming, and noticeably smaller crowds than July and August, making it one of the best months overall.

When is the best time to see the Oia sunset without huge crowds?

Visit in the shoulder months (May, early June, late September or October). In peak summer the Oia sunset draws large crowds, so arrive well before sundown to secure a spot.
