Mykonos in August: Weather, Crowds and What to Do

August is Mykonos at full volume: hot, dry and sunny, with the island at its busiest and beach clubs and nightlife in full swing. It suits anyone who wants warm swimming, beach clubs and late nights. Most first-timers who aren't chasing nightlife will be happier in September, which keeps most of the beach weather and drops much of the crowd.

What is the weather like in Mykonos in August?

Expect hot, dry, sunny days and warm evenings. The whitewashed lanes throw the sun back at you, shade is scarce, and the wind keeps the heat from feeling as strong as it is, so sunburn comes easily. Sightseeing is more comfortable before 11 a.m. or in the early evening. The sea is close to its warmest of the year, and a swim fits into almost any day.

Rain is very unlikely. Wind is the weather that changes plans. Mykonos is nicknamed the Island of the Winds, and the Meltemi, a dry northerly summer wind, is one of the defining features of August. It cools hot afternoons, but a strong spell can last several days, roughing up exposed beaches and affecting boats.

On windy days, beach choice matters more than water temperature. Ftelia, Panormos and Agios Sostis on the north coast are lovely when it's calm and miserable in a strong Meltemi. Psarou, Platis Gialos and Ornos offer more shelter from the wind, though during a strong Meltemi even they can feel its force. Check the forecast each morning and pick your beach to match. The wind rarely ruins a whole trip, so it is no reason to cancel one.

Evenings stay warm, but the breeze on a waterfront terrace or a ferry deck can feel cool.

How does August compare with July and September?

July is nearly a twin. It is just as hot and dry, the swimming is just as good, and the crowds are a bit smaller. Choose it for the same peak-season buzz with slightly more room. Pick August if the busiest beach clubs and liveliest nightlife are exactly what you are after.

September is the gentle step down. The sea is still warm, the sky is still clear, and the island stays lively, especially in the first half of the month. Hotel rates ease, restaurant tables are easier to get, and the beaches have more room to spare.

Is August a good time to visit Mykonos?

Yes, if you go in with a plan. Virtually every seasonal business on the island is open, from hotels and restaurants to shops, clubs, tour operators and beach services. Expect the heaviest crowds during the opening three weeks, particularly near August 15, the Feast of the Assumption, when Greek holidaymakers join the usual flow of visitors. The final week of August tends to feel a little calmer once the holiday rush has passed. It's still peak season, though, with busy beach clubs and high hotel prices.

Prices follow the crowds. Hotel rates sit at their yearly peak, beach clubs are expensive, and villas and transfers are in high demand. Book your hotel four to six months ahead if you can, since good-value hotels, family rooms and the best locations go first. Arrange airport and port transfers through your hotel or a transfer company, and don't count on a taxi waiting when you land. It pays to reserve ahead for dinners in Mykonos Town, Little Venice and the popular beach restaurants, and sunset tables can be especially tough to get.

How do you get around Mykonos in August?

Getting around starts with where you sleep, and location matters more than how fancy the hotel is. Mykonos Town is the best base for restaurants and nightlife, because you can walk home. Ornos is the easiest all-around beach base for first-timers and families, with restaurants and regular buses to town. Hotels, restaurants, bus stops and the south-coast water taxi all sit near one another at Platis Gialos. Psarou is for the high-end scene. A remote villa can look like good value until you try to get anywhere, so solve the transportation question before you book.

Taxis are scarce, Uber is no guarantee when demand is high, and roads clog. Buses are inexpensive and handy for getting between town and the main beaches, though the popular routes fill up.

A rental car helps at a remote hotel or for exploring far-flung beaches, but it doesn't solve traffic or parking, and it is no way to get to dinner in town. Book it early. U.S. drivers must carry a valid U.S. license, and insurance companies may require an international driver’s permit. Thieves target rental cars, so leave passports and valuables out of sight or back at the hotel. Transport strikes can disrupt taxis and seaports, and summer forest fires occasionally close roads.

Ferries run often to Athens, Santorini, Paros, Naxos and Tinos, but demand is heavy. Popular high-speed departures can sell out, so book them several months ahead, particularly around August 15. The bigger conventional ferries give a more comfortable ride in rough seas, though wind can delay any ferry. Allow plenty of time at the port, where traffic is heavy and boarding can feel chaotic. Don't connect straight from a ferry to an international flight; spend the last night in Athens.

What should you pack for Mykonos in August?

Pack light, breathable clothing for hot days and a light layer for breezy evenings and ferry decks. Bring a hat, sunscreen and sunglasses for the strong sun, and sturdy shoes for uneven ground. A reusable water bottle earns its place under the hot sun, especially on Delos.

What is there to do in Mykonos in August?

Pick one or two beach club days you truly care about, since chasing reservations and minimum spends all week wears thin. Popular tables and events at clubs such as Scorpios, Solymar and Alemagou fill well ahead. Booking a table at a beach restaurant may not come with sunbeds, and a sunbed reservation may not cover entry to a special event, so look closely at what your payment includes.

The boats depend on sea conditions and a few stops have fewer departures, so find out when the last boat back leaves before you go.

Mykonos Town is at its calmest early, before 9 a.m., when most shops are still closed and cruise passengers have not yet arrived. That is the time to photograph the windmills, Little Venice and the Old Port. Come back at night for dinner, shopping and bars. Shops keep late hours, and the bars fill up as the night goes on. Mykonos is also one of Europe's most popular destinations for gay travelers, with a lively gay nightlife. Plan your ride home before you go out, because hunting for a taxi at 3 a.m. rarely works.

Delos is exposed, rocky and nearly shadeless, so take the earliest crossing, wear a hat and bring plenty of water. Wind can often cancel smaller boat excursions and affect Delos crossings, so check the weather policy before booking a boat tour, and try to keep Delos and your only boat day off your final morning.

August festivals include the XLSIOR Festival and the Panigiri Traditional Feast.

What do Americans need to enter Greece?

U.S. citizens can enter Greece without a visa for up to 90 days of tourism or business. Your passport should have at least three months of validity beyond your planned departure date, and a passport previously reported lost or stolen will be refused at the border. Be ready to show proof of sufficient funds and a return ticket or other evidence of departure if asked. Greece is a generally safe destination, though petty crime is common in popular tourist spots. Carry your passport or another photo ID at all times.
