September is one of the best months to visit Mykonos. The weather is warm, the sea is near its warmest, and the island remains lively with fewer crowds and less traffic than August.

Early September still feels like high season, with busy beach clubs, strong nightlife, and expensive hotels. Mid and late September are calmer, easier, and better value.

My advice: For most visitors, September 10–20 is the sweet spot. The sea is warm, beach clubs and restaurants are still open, and the worst August crowds have gone. Visit earlier for the biggest parties or later for quieter beaches and better hotel prices. Unless peak party season is your main reason for visiting, I’d choose September over July or August.

Mykonos in September at a Glance

• Weather: Warm and sunny, with daytime highs commonly around 24–27°C (75–81°F).
• Swimming: Excellent. The sea is warmer than in June and comfortable throughout the month.
• Wind: The Meltemi is less persistent than in August, but windy days still occur.
• Rain: Uncommon early in the month, with a greater chance of showers later.
• Crowds: Busy early in the month, noticeably quieter by mid-September, and relatively calm by the end.
• Prices: High at the beginning of September, with better hotel value later.
• What is open: Almost everything early and mid-month. Some seasonal businesses begin winding down near the end.
• Main downside: Hotels are still expensive early in the month, and some beach clubs and boat services reduce their schedules in late September.

Early September vs. Late September

• Early September: Still high season, with busy beach clubs, strong nightlife, expensive hotels, and popular restaurants that require reservations.
• Mid-September: My favorite time to visit. The weather and sea are excellent, nearly everything is open, and crowds and prices begin to ease.
• Late September: Quieter and much better value. Most major hotels and restaurants remain open, but some beach clubs and seasonal businesses begin winding down.

September Weather, Swimming, and Wind

September remains warm and summery, particularly during the first three weeks. Days are sunny enough for beaches and pools, but the heat is less tiring than in July and August.

Daytime temperatures commonly reach 24–27°C (75–81°F). Rain is possible later in the month, but prolonged wet weather is unusual. Sea temperatures are around 23–24°C (73–75°F), making September one of the best months for swimming.

The Meltemi weakens compared with August but does not disappear. Strong northerly winds can still affect exposed beaches, ferries, and small-boat trips.

On windy days, choose south-coast beaches such as Ornos, Psarou, Platis Gialos, Paraga, and Paradise. Save Ftelia, Panormos, and Agios Sostis for calmer conditions.

Bring a light sweater or jacket for breezy evenings and ferry decks. Comfortable shoes are useful for Mykonos Town and Delos, and motion-sickness medicine is worth packing if you’re sensitive to rough crossings.

Where to Stay in Mykonos in September

• Mykonos Town: Best for restaurants, nightlife, shopping, and car-free evenings.
• Ornos: Best all-around beach base for families and first-time visitors, with restaurants, buses, and easy access to Town.
• Platis Gialos: Best for an easy beach vacation, with hotels, restaurants, buses, and boats close together.
• Psarou: Best for luxury hotels, upscale beach clubs, and expensive sunbeds.
• Agios Ioannis: Best for couples, sunset views, and a quieter hotel stay.
• Elia: Best for larger beach resorts and more space, but less convenient for restaurants and nightlife in Town.

What Is Open in September?

Mykonos does not shut down after August. Most hotels, restaurants, beach clubs, and shops remain open throughout September.

• Hotels and restaurants: Most stay open all month, especially in Mykonos Town and the major beach resorts.
• Beach clubs: Most major clubs remain open through September, but parties and special events become less frequent later in the month. Closing dates vary.
• Nightlife: Strongest early in September but still lively in Mykonos Town later in the month.
• Tours: Delos excursions, sailing trips, and guided tours continue, weather permitting.
• Ferries: Connections to Athens, Santorini, Paros, and Naxos operate in September. Some inter-island routes are seasonal and do not run daily.
• Beach services: Sunbeds, restaurants, and water sports remain widely available at the main beaches.

In the final week of September, check directly when a specific beach club, boat trip, or seasonal restaurant is essential to your plans.

What to Book Before Arriving

• Hotels: Book early for the best hotels, especially during the first half of September. Late September offers more availability and better rates.
• Beach clubs: Reserve sunbeds and restaurant tables ahead at popular clubs such as Scorpios, Nammos, SantAnna, and Principote, especially in early September. Check event schedules separately.
• Restaurants: Reserve popular restaurants and sunset tables in advance. Casual restaurants are easier after mid-month.
• Ferries: Book once your island-hopping itinerary is fixed. Check sailing days before committing to hotels on multiple islands.
• Transfers: Book airport and port transfers ahead, especially for late arrivals, hotels outside Town, or travelers with lots of luggage.
• Rental car: Not necessary if staying in Town, Ornos, or Platis Gialos and using the nearby beaches. Rent one for exploring remote beaches and less-connected parts of the island.
• Boat tours: Book popular trips ahead, but avoid scheduling your only possible boat trip on your final day in case strong winds cause cancellations.

Best Things to Do in September

Spend Several Days at the Beach

September is arguably Mykonos’s best beach month. Ornos and Platis Gialos are the easiest all-around choices. Psarou and Paraga are best for upscale beach clubs and sunbed service. Agios Sostis and Panormos are better on calm days.

Explore Mykonos Town

Come for dinner, shopping, Little Venice, the windmills, cocktail bars, and nightlife. Mykonos Town stays lively throughout September, even as the beach resorts become quieter.

Take a Delos Day Trip

September is one of the best months to visit Delos. The site is exposed and almost completely without shade, so the milder weather is a major improvement over midsummer.

Go Beach Hopping or Take a Boat Tour

Beach boats connect Platis Gialos with several south-coast beaches, including Paraga, Paradise, Super Paradise, Agrari, and Elia. Services are seasonal and weather-dependent, with fewer departures possible later in September. Sailing trips to Rhenia and Delos are also good options.

Ferries and Getting Around

September is a good month for island hopping between Mykonos, Santorini, Paros, and Naxos. Check ferry schedules before booking hotels, especially for routes between islands.

• Athens to Mykonos: Ferries operate from Piraeus and Rafina. Rafina is closer to Athens Airport, while Piraeus is more convenient from central Athens.
• Mykonos to Santorini: Seasonal high-speed ferries connect the islands in September. Check schedules before booking hotels, as departures are not equally frequent every day.
• Mykonos to Paros or Naxos: Both are easy additions and offer a more relaxed island experience after Mykonos.

Mykonos ferries use the New Port at Tourlos, not the Old Port in Town. Arrange transportation in advance when traveling with luggage. Buses remain useful for the main beaches, but taxis are limited, especially when several ferries or flights arrive close together.

Do not connect a ferry to an international flight from Athens on the same day. Spend your final night on the mainland.

For schedules and booking, see my Greek Ferry Guide and check current sailings on Ferryhopper.

September vs. August and October

August or September?

August has bigger parties, higher prices, heavier traffic, and much larger crowds. September has warm swimming, good nightlife, and most restaurants still open, with fewer people and less traffic.

Unless peak party season is your main reason for visiting, choose September.

September or October?

September is the better choice for beach weather, swimming, nightlife, and ferry connections.

Early October can be lovely, but weather becomes less dependable and seasonal hotels, clubs, restaurants, tours, and ferry routes begin closing. Choose September for a reliable beach vacation and October for lower prices and a much quieter island.
