June is the month the sea becomes properly warm. The water reaches around 22 to 23C, comfortable for everyone and a clear step up from the cooler spring seas, making this the first month of the year when swimming is reliably pleasant rather than bracing. The black-sand beaches of Perissa, Perivolos and Kamari are fully open and lively, with sunbeds, beach bars, tavernas and watersports all running, and the warm, clear water is great for swimming, snorkeling and boat trips. June is therefore an excellent choice for travellers who want genuine summer beach and sea time alongside the island’s sights, set out alongside the guides to the beaches and watersports. The crowds are building.
What are the crowds and prices like?

The island is busy, with the famous spots, Oia at sunset, Fira in the evening, the popular boat trips, the caldera-view restaurants and the harbour, all feeling lively and, by late June, very busy. There is a real difference within the month: early to mid-June is noticeably calmer, with somewhat lower prices, better availability and a gentler feel, while late June is effectively high season, with higher hotel rates, busier ferries and tighter restaurant bookings. For the best balance of warm weather, manageable crowds and reasonable prices, early to mid-June is the ideal window, set out alongside the guides to the sunset and best time to visit Santorini. There is everything to do.
What are the best things to do in June?
In June you can do everything: swim and enjoy the beaches in the warm sea, take a caldera and volcano cruise, walk the Fira-to-Oia path early in the day to beat the heat, watch the sunset from Oia, and tour the wineries. The long, sunny days and warm water make it ideal for the full summer experience.
June opens up the island’s full summer programme. The warm sea makes it a prime month for beach days at Perissa and Kamari, swimming, snorkeling and the popular caldera and catamaran cruises to the volcano and hot springs, often ending with the sunset from the water. The Fira-to-Oia caldera hike is best tackled early in the morning or late afternoon to avoid the building midday heat, and the villages, sunset at Oia, and the wineries are all in full swing. Booking ahead for the sunset cruises, the best restaurants and Oia sunset spots is wise as June progresses and demand grows. It is a superb all-rounder of a month, set out alongside the guides to Santorini boat tours and the Fira to Oia hike. The questions below cover the points travellers ask most.
