August 15 (Dekapentavgoustos): the Assumption of the Virgin Mary is Greece’s biggest summer holiday. In 2026 it falls on a Saturday, so ferries and hotels around that weekend book out early and many businesses keep holiday hours, with local church festivals (panigyria) across the island. August is peak season, so expect the highest hotel rates of the year and the busiest ferries – book accommodation and any high-season ferry well in advance.
August is a very stable, dry and sunny month weather-wise, so prepare for consistent heat day and night across the volcanic island, with the strong Meltemi winds providing the only real relief.
| Santorini in August | Avg High | Avg Low | Sea Temp | Rainy Days |
|---|---|---|---|---|
| Early August | 30°C / 86°F | 23°C / 73°F | 24°C / 75°F | 0–1 |
| Mid August | 32°C / 90°F | 24°C / 75°F | 25°C / 77°F | 0 |
| Late August | 31°C / 88°F | 24°C / 75°F | 26°C / 79°F | 0 |
In August you’ll walk the streets of Fira and Oia or the black sand beaches of Kamari and Perissa in t-shirts and shorts all day. You may want a light layer for the evening, but honestly, you’ll rarely need it.
Where should I stay in Santorini in August?
For caldera views, stay in Fira, Firostefani, Imerovigli, or Oia; to be on the beach, choose Perissa, Perivolos, or Kamari. August is the heart of summer and high season in Greece, so prices are high and availability is very limited — the best caldera-view and luxury hotels sell out far in advance. If you have a specific hotel in mind, book at least 6–12 months ahead.
In August you’ll see big crowds on the streets of Oia around sunset, and it stays packed pretty much all day long.
August is also when most Greeks take their holidays — it’s the “official” holiday month in Greece, which adds even more domestic travelers to the mix.
It’s worth knowing that August 15 is one of the biggest holidays in Greece — “Dekapentavgousto,” the Feast of the Dormition of the Virgin Mary (her assumption into heaven).
Across the country it’s a public holiday and many businesses shut down, but in Santorini you should expect no disruptions: it’s the heart of the season, and most businesses rely on that “sweet” summer revenue. Around mid-August, ferries are especially busy as the Greek and European holidays overlap, so book your crossings early.
August is also the busiest month of the year for cruise-ship arrivals in Santorini, and in my opinion that’s the worst thing for the island. Since 2025, Greece has capped cruise arrivals at 8,000 passengers per day — and the cap tightened further in 2026 — to ease the crush, but big ships still flood the island in summer. Cruise passengers contribute relatively little to the local economy while adding enormously to the crowds, so don’t expect August’s caps to make the island feel quiet.

August is NOT a great month for a honeymoon in Santorini, as it’s packed, busy, crowded, and expensive everywhere. Honeymooners are far better off visiting in June or September.
Handy tips for choosing a hotel in Santorini in August (and beyond):
- For volcano and caldera views:Fira, Firostefani, Imerovigli, Oia
- For being close to all the bars, restaurants, shops, nightclubs, and the buzz: Fira (the capital, with the most shops, grocery stores, and nightclubs) and Oia
- For equally beautiful sunsets and caldera views without the thousands of tourists:Imerovigli and Firostefani
- For being closer to the famous black sand beach (about a 5-minute walk) and the best beach bars on the island: Perissaor Perivolos (no famous caldera or volcano views, though)
- For being closer to the other black sand beach with lots of restaurants and amenities:Kamari (no famous caldera or volcano views)
- For being close to the famous Red Beach while still having caldera views: Akrotiri (but it’s a 20–30 minute drive from Fira, the capital)
- For being closer to most of the Santorini wineries (if you’re not worried about the famous caldera views):Pyrgos or Megalochori
- For the best private pools and jacuzzis with caldera views, stay in Imerovigli or Firostefani.
What do I need to pack for Santorini in August?
Pack strictly for summer: swimsuits, t-shirts, shorts, summer dresses, sandals, and flip-flops — plus high-SPF sunscreen, a hat, and sunglasses for the intense midday sun. Summer is in full throttle in Santorini, and you’ll also want comfortable walking or hiking shoes (yes, you’ll do some hiking — sitting by the pool with a cocktail all day isn’t great for you!).
Bring all the summer clothes you can, and pack one light jacket or layer for the rare cooler night (most likely in the first half of the month, when the Meltemi winds are strongest).
How hot is Santorini in August?
Santorini is very hot in August, with daytime temperatures usually between 29–33°C (84–92°F) and warm nights around 23°C–25°C (73–77°F). Expect the peak summer heat to hover around 32°C (90°F) at midday. During a heatwave the peak can hit 38–40°C (100–104°F), and the strong Mediterranean sun makes it feel even hotter, so sun protection and shade are essential at midday.
The sea temperatures are at their warmest of the year — about 24–26°C (76–79°F), with the sea at its warmest in late August — so you’ll get the best beach weather Santorini can offer. It’s the ideal time to enjoy the beach clubs in Santorini, which throw their biggest parties of the year in July and August.
The black sand beaches of Perissa, Perivolos, and Kamari are buzzing all through August.

Is August a good time to go to Greece?
August is not the best time to visit Greece if you want to avoid crowds, but it’s perfect if you want peak summer energy. The weather is hot, dry, and sunny and the sea is at its warmest, but everywhere you go will be busy and packed. Whether August is a good time to visit Santorini really depends on your travel style: it isn’t ideal for a honeymoon, yet it’s great for solo travelers and groups who want vibrant nightlife, beach parties, and the buzz of peak season.
Is Santorini windy in August?
Yes, Santorini can be windy in August because of the Meltemi — strong, dry northerly winds that sweep across the Aegean every July and August, with gusts that can reach 50–60 km/h. The Meltemi takes the edge off the midday heat, but it can make the sea choppy and occasionally disrupts ferry crossings. Here’s the average wind speed in Santorini through the year:
What things can I do in Santorini in August?
In August you can do everything Santorini offers — swimming, beach clubs, boat tours, wine tasting, and sightseeing — since every business, tour operator, and hotel is fully open. Here are the best things to do:

- Go wine tasting at any of the best wineries on the island (the most detailed wineries guide on the internet!)

Conclusion: Is Santorini worth visiting in August?
Santorini in August is worth it for the weather and beach life, but the crowds make it my least-recommended month. You’ll have a fantastic time on the island whenever you arrive, but I genuinely believe May, June, and early October are the best times to visit.
In those months you’ll avoid the worst crowds, enjoy the scenery with fewer people around, skip most of the enormous cruise ships, and often get better hotel and tour prices.
Overall, I don’t recommend visiting Santorini in August — but if it’s the only time you can come, you’ll experience the best weather and the best beach life this place has to offer.
