Santorini in summer is 28 to 32 degrees, a sea at 24 to 26, no rain from June to early September, the meltemi wind from mid-July, and every famous view crowded between eleven and five. Everything is open and every boat runs when the wind allows. Move your day to the edges, take the sights at opening and the island back after six, and it is the best version of the island.

Santorini summer tours
Plato and some stubborn archaeologists may be right and, yes, here was the “lost Atlantis”. Many trumps are making Santorini ideal and Santorini Tours is the ideal way to explore them. Even when there are 5,000 people on the same rock to see the sunset, even then the island does not lose its energy.
From the crowds of Fira to the metaphysical breeze of Finikia and from the healing waters of Old and New Kameni to the sophisticated groups of Oia, the theatrical land hides miracles: if you walk barefoot, you will see and believe them.
Get to know the old Fira
Τhe vineyards and the top of the house, a goula (defensive tower-observatory, from the Turkish word “kulees”) belonging to the Botsi family. Even when tourism is at its peak, there are quiet, memory-filled corners, such as Frangomahalas with its mansions, Gyzis Megaro, Catholic Cathedral, Lazariston Monastery, the Dominican Monastery of the Monks and the Brothers of Mercy.
For those who seek serenity, it is ideal to take a stroll down to the quiet Kato Fira and then walk a passage from the “bouti” (low wall), the most central street of Fira, with a breathtaking view. You can use Santorini transfers in order to meet all the corners of the island.
Visit the unique excavation in Akrotiri
Akrotiri dates back to the Late Neolithic Era, 4000 BC, so it is definitely a monumental settlement and it has a lot to tell us. Fortunately, the excavations started again. The findings testify to the cosmopolitan character of the area.
The close diplomatic and commercial relations with the Mediterranean ports made Akrotiri a sturdy economic harbor, which is also reflected in eating habits: a popular delicacy was the garos, a fine fish sauce that was celebrated by Sophocles and Plato.
Also, souvlaki originates from the Aegean Sea, baked in straws in Santorini 6,500 years ago. Gastronomy has always been another advantage (dry tomatoes, white aubergines, beans: three famous local specialties).
If you would like to have a full Akrotiri private tour you need to make your reservations now!
Experience the vintage experience in its ancient vineyards
The study of DNA grapes found in Minoan jars demonstrates that Asyrtiko is an avid Mediterranean variety. The vineyard of Santorini is one of the most important of Europe – here wine tourism is in its peak, especially from mid-August onwards, when the harvest begins.
The winemakers of the island welcome us and teach us everything about Mandilaria, Mavrotragano, Aidani, Athiri and, of course, Asyrtiko.
Santorini cave houses
You will understand better if you enter one of the Santorini caves. They are not houses, they are architecture courses – even Le Corbusier put them in the eye.
Tholos, dug in the rock without foundations, the caves are carved on the vertical front of the white (volcanic matter). It is also bioclimatic: warm in winter, cool in the summer (the Theraine land has insulating properties).
Wander into a landscape of science fiction
It is not only the Caldera, the volcanic volumes, the Aegean blue and the light that is “like nowhere”. The whole of Santorini is a cinematic scenery. In Emborios, the largest village on the island, the irregular, rounded shapes of the houses remind the settlements of the “Star Wars”.
In Finikia, like another Indiana Jones, you are walking in other worlds: half-broken canvases-souvenirs of a glorious wine age, prickly pearls, infinite alleyways, faded blue and red colors, broken door and courtyard lockings all secret.

Santorini in Summer: The Short Answer
Santorini in summer is hot, dry, spectacular and extremely busy. Expect 28 to 31 degrees by day, a sea at 24 to 26, no rain worth the name from June to early September, and the meltemi wind arriving in July. Everything is open, every boat runs when the wind allows, and every famous view has a crowd in front of it between eleven and five.
The trick is not avoiding the season. It is moving your day to the edges of it: sights at opening, nothing outdoors in the middle, and the island back to yourself after six. Done that way santorini in summer is the best version of the island. Done the other way it is a queue in the heat.
June and early September are the two months of santorini in summer to book if you have a choice. July and August are hotter, busier and windier, and they still work if you plan around the clock rather than around a list.
What the Weather Actually Does
June. 26 to 29 degrees, sea at 22 to 24, long evenings and manageable crowds. The best month of santorini in summer by a clear margin.
July. The hottest half of santorini in summer starts here: 29 to 31, sea at 24 to 25, and the meltemi starts. Hot, dry, bright, and the first month where midday is genuinely unpleasant on exposed ground.
August. 29 to 32, sea at 25 to 26, peak crowds, peak prices and the strongest wind of the year. It is also when the island is at its most alive.
Early September. 27 to 29, sea still 25, crowds thinning after the first week. The other month to book.
Rain. Santorini in summer gets effectively none. Santorini gets around 350 millimetres a year and almost all of it falls between November and March.
Humidity. Low, which is why 31 degrees here is far more bearable than 31 in Athens.
The wind. The meltemi blows from the north for two or three days at a time, hardest from mid-July to late August. It makes the heat pleasant and it cancels boats.
See the weather month by month for the full table.
The Rule That Makes Summer Work
One rule decides everything else about santorini in summer: nothing outdoors between eleven and four.
Sunrise to 08:30. Oia, the blue domes, the castle ruin, the rim path. Empty, cool, and the light behind you.
08:30 to 11:00. Akrotiri and Ancient Thira at opening. Both are far better before the coaches.
11:00 to 16:00. A pool, a shaded terrace, a long inland lunch, a museum, or a boat where there is always a breeze. This is the part of santorini in summer that people get wrong.
16:00 to sunset. Wineries, beaches, Pyrgos, Emporio, Imerovigli. This is when santorini in summer reopens.
Sunset. The Akrotiri lighthouse, Imerovigli, Firostefani or from the water.
21:00. Dinner, inland, when it has finally cooled.
Visitors who follow that see twice as much and suffer half as much. It is also why a santorini in summer trip needs one more night than the same trip in May: you lose five hours of every day to the heat.
The Sea and the Beaches
The water in santorini in summer is at its warmest of the year, between 24 and 26 degrees from July to September, and it stays swimmable well into October.
Black sand gets dangerously hot. Perissa, Perivolos and Kamari can burn bare feet by eleven. Bring something to walk in.
Where the wind matters. The south and east coasts are sheltered when the meltemi blows. Vlychada and Perivolos stay calm on days when the north is impossible.
The best beach hours in santorini in summer. Before eleven and after five. In between the sand is unbearable and the sunbeds are all taken anyway.
Sunbeds. 15 to 30 euros for two with an umbrella, and usually free if you eat at the attached taverna.
Red Beach. Landslide-prone and officially discouraged. See it from the viewpoint above.
Beaches are the one part of santorini in summer where the island is merely good rather than exceptional. See the beaches ranked.
The Crowds, Honestly
Santorini in summer takes most of the two to three million visitors a year who arrive on an island of 76 square kilometres with about 15,000 residents, and most of them come between June and September.
Cruise ships. Up to five a day in the bay, each landing one to three thousand people into two villages between ten and five. The schedule is published, and checking it is the single most useful thing you can do before planning a day.
Oia at sunset. Several thousand people on one castle ruin, coach parties with meeting points, and a walk back up in the dark. It is the emblem of santorini in summer and it is the least pleasant hour of the week.
The cable car. An hour’s queue in each direction at midday in santorini in summer, and nothing at nine in the morning.
What is never crowded. Ancient Thira, the inland villages, the south coast beaches, the wineries after four, and the whole island before nine in the morning.
The 07:30 rule. Oia at half past seven in the morning is empty, cool and level. It is a different village from the one at noon, and it costs nothing but an alarm.
Crowding in santorini in summer is almost entirely a problem of hours and locations, not of the island. Move both and it mostly disappears.
What to Do in Santorini in Summer
A boat day. The best possible use of a hot day in santorini in summer, because there is always a breeze and you can swim off the back. Five to seven hours on a catamaran with lunch on board, and the caldera cliff turning gold at the end of the afternoon.
Akrotiri at opening. Roofed, shaded and cool, and the one major site that works even in August. Far better with a licensed guide. See Akrotiri.
Three wineries from four o’clock. Assyrtiko is a summer wine, and the terraces catch the evening breeze. See the wine tour.
The inland villages at six, which is when santorini in summer is at its best. Pyrgos, Emporio, Megalochori and Exo Gonia empty out when the ships leave and cool down when the sun drops.
The rim path early. Fira to Imerovigli in twenty level minutes, or the full ten kilometres to Oia if you start at seven. Never at midday in summer.
The volcano, early or not at all. Nea Kameni is black rock with no shade, and the climb at noon in August is genuinely hard.
A late beach. Perivolos or Vlychada from five, when the sand is walkable again.
The open-air cinema at Kamari. Films under the stars with a drink, and the most purely enjoyable evening of santorini in summer.
Festivals and Nights Out
Santorini in summer has a calendar of its own, and it is the reason many people prefer these months.
Panigiria. Village saint’s-day feasts with food, wine and dancing, and everybody is welcome. There are several across the summer, and Ai Giannis at Vothonas in late August is one of the best.
The Ifestia festival. A re-enactment of the volcanic eruption with fireworks over the caldera, usually in late August or September.
Santorini Jazz Festival. Mid-July, at Kamari, on the beach.
Assumption, 15 August. The biggest religious day of the Greek year and the busiest date of santorini in summer. Churches full, families gathered, and the island at its most Greek.
Nightlife. Fira from eleven for bars and clubs, Oia for quiet expensive terraces, Perissa and Perivolos for beach bars. Nothing starts before eleven, and santorini in summer keeps going until the buses restart in the morning.
See nightlife and island traditions.
The Meltemi
The wind deserves its own section, because it is the only thing that reliably breaks a santorini in summer plan.
What it is. A dry northerly that blows across the Aegean from mid-July to late August, sometimes for three or four days at a time.
What it does. Drops the felt temperature by several degrees, makes the beaches on the north and west uncomfortable, and cancels boats above about force six.
How to plan around it. Put your boat day early in the week, never on the last day, so a cancellation can be moved rather than lost.
What to do on a windy day. Akrotiri, the two museums in Fira, the wine museum, three wineries, and lunch in a sheltered inland village. None of them care about wind.
Anyone who has spent a santorini in summer here will tell you the meltemi is a gift on land and a nuisance at sea, and both are true on the same afternoon.
Where to Stay in the Heat
The village matters more in santorini in summer than in any other season, because shade, steps and a pool stop being luxuries.
Firostefani. Caldera view with road access, ten level minutes from Fira, and cheaper than Oia. The best all-round base. See Firostefani.
Imerovigli. The best view on the island and a great many steps, which matter more at 31 degrees with a suitcase.
Fira. Central and on the bus network, and the noisiest place to sleep in santorini in summer.
Oia. Beautiful, impractical and at its most crowded now. No vehicle access, hotels fifty to eighty steps below the road. See Oia.
Kamari, Perissa, Perivolos, Monolithos. Flat, cheaper, on a beach, and the right answer with children or without a car. See Kamari.
Megalochori and Pyrgos. Inland, quiet, the best food, and noticeably cooler in the evening. See Megalochori.
Non-negotiable. Air conditioning, and a pool or the sea within walking distance. Ask for the number of steps in writing before booking anything on the rim.
See where to stay for the full comparison.
What It Costs
Santorini in summer is the most expensive part of the year, and the gap between the rim and everywhere else is large.
Hotels. 90 to 160 a night inland or on a beach, 250 to 400 on the caldera, 500 and up for a cave suite with a plunge pool.
Car hire. 60 to 70 euros a day in August, against 25 to 45 in the shoulder season.
A shared catamaran. 90 to 140 each with lunch.
Dinner. 35 to 55 for two inland, 90 to 160 on the caldera rim.
Sunbeds. 15 to 30 for two, free with lunch at most tavernas.
Wine tasting. 20 to 35 each at most wineries.
The saving that matters. Sleeping inland and eating inland five nights out of six takes several hundred euros off a week for two, and a santorini in summer trip done that way costs roughly what three nights on the rim costs.
What to Book Before You Come
Very little can be arranged on arrival in santorini in summer, which is the main practical difference from spring.
Hotels. The good caldera rooms for early August are gone by February.
The boat. A week or two ahead in July and August, and early in your stay so wind cancellations can be moved.
Caldera-rim dinner. Weeks ahead for a sunset table. One night is enough.
Wineries. Essential at the big terraces now.
Car hire. A fortnight ahead, with a child seat specified in writing if you need one. See car hire.
Transfers. A few days, and more around 15 August. See transfers.
A guided day. A fortnight in high season.
What not to book. Anything at all on your arrival day, and a ferry on the day of a flight.
What to Pack
Shoes you can walk in. The villages are cobbled and stepped and flip-flops fail on both.
Something for hot sand. Black beaches are unwalkable barefoot by eleven.
A hat and real sun protection. There is almost no natural shade anywhere on the island.
A light layer for the evening. The meltemi makes rim terraces cool after ten.
A refillable bottle. Tap water is desalinated and safe to wash in, but everyone drinks bottled.
Swimming shoes. Useful on the pebbles at Kamari and Vlychada.
Pack for heat and stone rather than for photographs, and santorini in summer is a great deal more comfortable than the postcards suggest.
A Five-Night Summer Plan
The shape of a santorini in summer week that works when it is 30 degrees, written as we would book it ourselves.
Day 1. Arrive, nothing booked, a swim or a terrace, dinner locally at nine.
Day 2. Akrotiri at opening. Lunch in Megalochori under a vine. Pool from one until five. Three wineries from five. Dinner at Pyrgos at nine.
Day 3. A boat at ten with swimming stops and lunch on board, back by six. Nothing in the evening.
Day 4. Oia at half past seven with a camera, breakfast back at the hotel, the whole middle of the day off, Vlychada from five, and one dinner on the rim, booked.
Day 5. Ancient Thira at opening or the rim path early, Kamari beach and the open-air cinema in the evening.
Day 6. A swim, then home.
Three outings, two empty afternoons, one spare day for the wind. That is a santorini in summer week that people come home happy from. See the full itinerary guide.
Summer Compared With the Other Seasons
Against spring. May and early June are cooler, quieter and cheaper, with a colder sea and a few closed places. Better for walking, worse for swimming.
Against autumn. Late September and October keep the warm sea of santorini in summer and lose the crowds, which for many visitors is the best trade on the calendar.
Against winter. No boats, half of Oia shut, and an island that belongs to its residents. Cheap, atmospheric and completely different.
The verdict. Santorini in summer is the version with everything open, every boat running and the sea at its warmest, and you pay for it in heat, price and people. If your dates are fixed by school holidays it works well. If they are not, book June or September and keep the rest.

How hot does it get? 28 to 32 degrees by day in July and August, 26 to 29 in June and September, with low humidity and cool evenings.
Is it too hot to visit? No, if you move your day to the edges. Sights at opening, nothing outdoors from eleven to four, and everything else after five.
How warm is the sea? 22 to 24 in June, 24 to 26 from July to September, and still swimmable in late October.
