Weather in Ios in June
Expect warm, almost completely dry weather in Ios in June, early summer. Average highs reach 26°C / 78°F, with lows of around 21°C / 69°F. Rain is almost unheard of. Sea temperatures average around 22°C / 72°F, comfortable for swimming. Summer weather here is shaped by the meltemi, a dry northerly wind that keeps the heat bearable but can make exposed beaches choppy. Ios is a hilly island in the southern Cyclades, and its bays face in every direction, so there's usually a sheltered beach somewhere. Daylight lasts about 14½ hours, leaving long, light evenings. Pack summer clothes, a light layer for the evenings and good sun protection. When the wind picks up, a light windproof layer is handy for evenings by the water. The sun is strong from mid-morning onwards, even when a breeze makes it feel cooler. It's comfortable to be out all day, though the midday sun is still strong.
Swimming in Ios in June
Swimming is excellent in Ios in June, with the sea averaging around 22°C / 71°F. The sea is swimmable now, but the warmest water comes in July, August and September, when August is at its best. Mylopotas and Manganari are local favorites. When the meltemi blows, north-facing beaches get rough, so head for sheltered bays on the south side. Beach bars and sunbeds are open, with more space than in July and August. No wetsuit needed.
Crowds & Prices in Ios in June
Crowds in Ios are moderate in June, with plenty of space at the main sights and beaches. You'll find better deals on rooms and car hire than in July and August. Staying slightly outside the main town usually means better value and more space. Early mornings and late afternoons are the quietest times at popular sights. Booking a few weeks ahead is usually enough.
