Weather in Santorini in July
Expect hot, almost completely dry weather in Santorini in July, the height of summer. Average highs reach 28°C / 83°F, with lows of around 23°C / 74°F. Nights stay warm, so air-conditioning helps. In the water, expect around 24°C / 75°F, properly warm for swimming. Rainfall is close to zero. Summer weather here is shaped by the meltemi, a dry northerly wind that keeps the heat bearable but can make exposed beaches choppy. Santorini is a volcanic island with little shelter or shade, and the caldera rim is often windier than the beaches below. Days bring around 14½ hours of daylight, leaving long, light evenings. Bring loose, light clothing, a wide-brimmed hat, strong sunscreen and sunglasses. When the wind picks up, a light windproof layer is handy for evenings by the water. Plan sightseeing for the early morning or evening, and keep the midday hours for the beach or a shaded taverna.
Swimming in Santorini in July
Expect the sea around Santorini to be about 24°C / 75°F in July, comfortable for long swims. The best swimming runs through July, August and September, and the water is still warming, reaching its peak in August. Good spots include Perissa and Kamari. On windy days, choose a beach sheltered from the north, where the water stays calmer. Arrive early to get space on the busiest beaches. No wetsuit needed.
Crowds & Prices in Santorini in July
July brings peak crowds to Santorini. Prices for rooms, car hire and ferries are at their yearly high. Cruise ships call regularly, so the busiest spots can be crowded in the middle of the day. The crowds concentrate at Oia at sunset, so for a calmer experience, visit Pyrgos and Megalochori or walk the caldera path early in the morning. Book rooms, ferries and car hire well in advance.
What's Open in Santorini in July
Ferries to Santorini from Piraeus and Rafina run at full summer frequency in July, but they sell out, so book ahead. The airport has direct flights from across Europe in the season, as well as flights from Athens. Everything is open, from hotels and tavernas to beach bars and boat trips. Archaeological sites and museums are on their longer summer hours.
Festivals & Holidays in Santorini in July
Saint days such as Prophet Elias on 20 July bring feasts to chapels across the country, often on hilltops. July is the start of the panigyri season, when villages celebrate their saints' days with music, dancing and long tables of food, often late into the night. In Santorini, as across Greece, these traditions are very much alive. Summer evenings are the time for festivals, open-air cinemas and late dinners outdoors.
Is July a Good Time to Visit Santorini?
Yes, July is worth it for sun, swimming and a lively summer buzz in Santorini. Expect highs of around 28°C / 83°F, lows near 23°C / 74°F and almost no rain. The trade-off is crowds and peak prices, so book early and plan around the busiest spots. If you'd rather have the same warm sea with more space, June, September or October would be a better choice.
Frequently Asked Questions
What time does the sun set in Santorini in July?
Sunset in Santorini is at around 8:40 pm at the start of July, around 8:35 pm in mid-July and around 8:25 pm by the end of the month, in Greek local time. Oia is the most famous place to watch it, but it gets very crowded, so Fira and Imerovigli along the caldera are good alternatives. Arrive at least half an hour early to find a spot.
How hot does Santorini get in July?
July is one of the two hottest months, with long, sunny days and almost no rain. The meltemi wind often takes the edge off the heat, but on calm days the midday sun is fierce, and heatwaves can bring a few days of extreme heat. Plan sightseeing for the morning or evening, and drink plenty of water.
Is July a good time to walk from Fira to Oia?
Only early in the morning or late in the day. July is hot, most paths have little shade and the midday sun is fierce. Start at dawn, carry plenty of water and wear a hat. The path follows the caldera rim and takes around three to four hours.
Do I need a car on Santorini in July?
Not necessarily. Buses link Fira with the main beaches and villages in July, and taxis are available, though they're busy. A car, scooter or ATV gives you more freedom to explore quieter corners, so book one early.
Is July or August better for visiting Santorini?
July is usually slightly better. Both months are hot, busy and expensive, but August is the absolute peak, especially around the 15 August holiday, when Greek families travel and ferries and rooms sell out. If you must go in August, book everything early.
