Weather in Kos in June
In Kos, June brings early-summer weather that is hot and almost completely dry. Expect highs of about 28°C / 82°F and overnight lows near 22°C / 71°F. Sea temperatures average around 22°C / 72°F, pleasant for a swim. Rain is almost unheard of. Kos is long and fairly flat, with sandy beaches along its coasts and a mountain ridge running along the south of the island. The meltemi, the northerly wind of the Aegean, blows on many days and takes the edge off the heat, though it can also whip up dust and rough seas. You get about 14½ hours of daylight a day, leaving long, light evenings. Pack light, breathable clothes, a sun hat, high-factor sunscreen and sunglasses. When the wind picks up, a light windproof layer is handy for evenings by the water. Get out early and late, and save the hottest hours of the afternoon for the water.
Swimming in Kos in June
June is a great month for swimming in Kos, with water temperatures around 22°C / 72°F. It's warmer later in the year, with the best swimming in July, August and September. Paradise Beach and Tigaki are local favorites. On windy days, choose a beach sheltered from the north, where the water stays calmer. Beach bars and sunbeds are open, with more space than in July and August. No wetsuit needed.
Crowds & Prices in Kos in June
June is a shoulder month in Kos, busy enough to feel lively but well below the summer peak. Prices are noticeably lower than in high summer, and there's more choice of rooms. Weekdays are calmer than weekends at the most popular spots. Staying slightly outside the main town usually means better value and more space. You can often book at short notice, except around holidays.
What's Open in Kos in June
Ferries to Kos from Piraeus run at full summer frequency in June, 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. Museums and sites are open on extended summer hours. Shops in tourist areas often stay open into the evening.
Festivals & Holidays in Kos in June
Whit Monday often falls in June, making a long weekend when Greeks head for the coast. Around 24 June, some villages still light bonfires for the feast of Saint John, and summer festivals begin. In Kos, as across Greece, these traditions are very much alive. Summer evenings are the time for festivals, open-air cinemas and late dinners outdoors.
Is June a Good Time to Visit Kos?

The only caveat is that a few seasonal businesses may be closed at the very start or end of the season.

Not necessarily. Buses link Kos Town with the main beaches and villages in June, 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 June or July better for visiting Kos?
June, for most travelers. It has the longest days, a swimmable sea and a summer atmosphere, with fewer crowds and lower prices than July. July is hotter and busier as school holidays begin, but it's the choice if you want the island in full swing.
