Weather in Ios in August
Expect hot, almost completely dry weather in Ios in August, the height of summer. Daytime highs average around 28°C / 82°F, and nights drop to about 23°C / 74°F. Nights stay warm, so air-conditioning helps. Rainfall is close to zero. The sea averages about 24°C / 75°F, warm enough for long swims. 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. Ios is a hilly island in the southern Cyclades, and its bays face in every direction, so there's usually a sheltered beach somewhere. You get about 13½ hours of daylight a day, 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. Get out early and late, and save the hottest hours of the afternoon for the water.
Swimming in Ios in August
Expect the sea around Ios to be about 24°C / 75°F in August, comfortable for long swims. Of the best swimming months, July, August and September, this is the warmest. Mylopotas and Manganari are local favorites. On windy days, choose a beach sheltered from the north, where the water stays calmer. Beaches are at their busiest now, so go early or late in the day.
Crowds & Prices in Ios in August
Expect Ios at its busiest in August, with the island's most famous spots packed from morning to night. Hotel prices are at their highest, and flights and ferries cost more too. Around 15 August, when Greek families travel, ferries and rooms sell out. Early mornings and late afternoons are the quietest times at popular sights. Book early, as the best-value rooms go first.
What's Open in Ios in August
In August, ferries from Piraeus and Rafina to Ios run often, with extra fast boats in the peak season. It's the full season, so hotels, restaurants, beach bars and excursions are all running. Archaeological sites and museums are on their longer summer hours. The bars and clubs of Chora are in full swing. Opening hours are long, with many tavernas serving until late.
Festivals & Holidays in Ios in August
Many Greeks return to their home villages in August, and panigyria, village feasts with live music and dancing, run late into the night. 15 August, the Dormition of the Virgin Mary, is the biggest summer holiday, with church services and village festivals everywhere. In Ios, these occasions are celebrated much as they are across the rest of Greece. Look out for posters announcing local feasts and concerts, often only a few days ahead.
Is August a Good Time to Visit Ios?
August is a great time to visit Ios if you want long beach days, a warm sea and the island at its liveliest. Expect highs of around 28°C / 82°F and lows near 23°C / 74°F. It suits families on school holidays and anyone who loves a busy summer atmosphere. It's less ideal if you dislike crowds or high prices. For a calmer trip with the sea still warm, consider June, September or October instead.
Frequently Asked Questions
What time does the sun set in Ios in August?
In early August, the sun sets in Ios at around 8:25 pm. By mid-month it's around 8:10 pm, and by the end of August around 7:50 pm. All times are Greek local time. Chora, especially near the church of Panagia Gremiotissa, has wide views to the west.
Is it windy in Ios in August?
Often, yes. August is the height of the meltemi, a strong, dry northerly wind that blows across the Aegean on many summer days, sometimes for several days in a row. It keeps the heat bearable, but it can make exposed beaches rough and delay fast ferries and small boats. South-facing beaches are usually more sheltered.
Can I visit Chora on Ios in August?
Yes. Chora on Ios is at its liveliest in August, but also at its busiest. Explore in the morning or after sunset, when it's cooler and the atmosphere is at its best. Climb to the church of Panagia Gremiotissa for the views.
Do I need a car on Ios in August?
Not necessarily. Buses link the port and Chora with the main beaches and villages in August, 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 August or September better for visiting Ios?
September, for most travelers. The sea is still warm, the crowds thin out after the first week or two and prices drop, while most businesses stay open. August is the choice only if you want the island at its busiest and liveliest.
