Platis Gialos in September.
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 without the crowds and transportation problems of 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 often better value.
My advice: Choose early September for nightlife and the full beach-club scene. Choose mid or late September for warm swimming, good restaurants, and a more relaxed trip. For most couples and first-time visitors, September is better than July or August.
Is September a Good Time to Visit Mykonos?
Yes. September offers the best overall balance of beach weather, warm water, nightlife, restaurant choice, and manageable crowds.
Mykonos does not shut down after August. Mykonos Town remains lively, the main beach resorts are operating, ferries run frequently, and most hotels, restaurants, bars, tours, and beach clubs remain open.
September is best for: Couples, swimming, beaches, restaurants, sightseeing, boat trips, and travelers who want nightlife without peak-August chaos.
The verdict: September is the best month for most people visiting Mykonos. It still feels like summer, but the island is easier to enjoy.

Early September vs. Late September
- Early September: Still feels close to high season. Beach clubs are busy, nightlife is strong, restaurants require reservations, and hotel prices remain high.
- Mid-September: The best balance for most travelers. The weather and sea are excellent, nearly everything is open, and crowds and prices begin to ease.
- Late September: Calmer, more relaxed, and often much better value. Most major hotels and restaurants remain open, but some beach clubs and seasonal businesses begin winding down.
Choose early September if parties and specific beach clubs are central to the trip. Choose mid or late September for swimming, restaurants, sightseeing, and a quieter couples’ vacation.
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.
The sea is one of September’s biggest advantages. Water temperatures are around 23–24°C (73–75°F), making it 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.
A light sweater, linen shirt, or jacket is useful for waterfront dinners, ferry decks, and breezy evenings.
One of my favorite beaches in Greece, Ornos Beach has warm swimming and a full selection of restaurants and hotels in September.
What Is Open in September?
Most of Mykonos remains fully operational through September.
- Hotels and restaurants: Most stay open all month, especially in Mykonos Town and the major beach resorts.
- Beach clubs: The main clubs are active in early and mid-September. Closing dates vary later in the month.
- Nightlife: Strongest early in September but still lively in Mykonos Town later in the month.
- Shops: Boutiques, galleries, jewelry stores, and souvenir shops remain open.
- Tours: Delos excursions, sailing trips, and guided tours continue, weather permitting.
- Ferries: Main connections to Athens, Santorini, Paros, and Naxos operate throughout the month, though some routes become less frequent later.
- 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
September is easier than August, but early September should still be treated as high season.
- Hotels: Book early for Mykonos Town, Ornos, Platis Gialos, Psarou, and Agios Ioannis. Late September offers more flexibility.
- Beach clubs: Reserve ahead for Scorpios, Nammos, SantAnna, Principote, and other famous venues, especially during the first half of September.
- Restaurants: Book important dinners and sunset tables. Casual places are easier after mid-month.
- Ferries: Reserve important routes once your itinerary is fixed.
- Transfers: Arrange airport and port transfers if arriving late, carrying substantial luggage, or staying remotely.
- Rental car: Useful for remote hotels and northern or eastern beaches. It is not necessary for a stay in Town, Ornos, or Platis Gialos.
- Boat tours: Book ahead but leave flexibility in case wind affects the route.
Platis Gialos is one of the easiest September bases, with a sandy beach, restaurants, buses, and boats to other south-coast beaches.
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, polished beach service, and the beach-club scene.
- Agios Ioannis: Best for couples, sunset views, and a quieter hotel stay.
- Elia: Best for larger beach resorts and more space, though it feels removed from Town.
For most September trips, choose Mykonos Town for dining and nightlife, Ornos or Platis Gialos for easy beach days, and Agios Ioannis for a quieter romantic stay.
Best Things to Do in September
Spend Several Days at the Beach
September is arguably Mykonos’s best beach month. The water is warm, the sun remains reliable, and the beaches become more comfortable as August crowds disappear.
Ornos and Platis Gialos are the easiest all-around choices. Psarou and Paraga are best for polished beach service and clubs. Agios Sostis and Panormos are better on calm days.
Visit a Beach Club
Early and mid-September are excellent for the Mykonos beach-club scene. During the final part of the month, check closing dates and event schedules directly.
Explore Mykonos Town
Mykonos Town remains lively throughout September. Come for dinner, shopping, Little Venice, the windmills, cocktail bars, and nightlife. Later in the month, evenings are more relaxed without feeling deserted.
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
Boats connect several south-coast beaches, and day trips to Rhenia, Delos, and the south coast remain excellent. Check current schedules later in the month and avoid putting your only possible boat day at the end of the trip.
Enjoy the Restaurants
September is one of the best months for dining. The full restaurant scene remains active, but service feels less rushed and tables become easier to secure as the month progresses.

Ferries and Getting Around
September is excellent for combining Mykonos with Santorini, Paros, Naxos, or Athens. The main routes remain active, but service becomes less extensive as autumn approaches.
- 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: A seasonal route with frequent September service. Book ahead, particularly early in the month.
- 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, taxis are limited, and a rental car is most helpful for remote hotels or exploring less-connected beaches.
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.
Paradise Beach in September. The beach remains lively, but finding space and booking a sunbed are easier than in August.
September Mistakes to Avoid
- Assuming early September is shoulder season: Hotels, restaurants, and beach clubs can still be busy and expensive.
- Not checking late-month schedules: Specific beach clubs, restaurants, tours, and boat services may reduce hours.
- Planning a ferry and international flight on the same day: Leave a buffer for wind and ferry delays.
What to Pack for Mykonos in September
- Swimwear, beach clothes, sunscreen, sunglasses, and a hat.
- A light sweater or jacket for breezy evenings and ferry decks.
- Comfortable shoes for Mykonos Town and Delos.
- Smart casual clothes for dinners and nightlife.
- Motion-sickness medicine if you are sensitive to rough ferries or small boats.
September vs. August and October
August or September?
August has larger parties, higher prices, heavier traffic, and much bigger crowds. September retains warm swimming, good nightlife, and the full restaurant scene but is easier in almost every practical way.
Unless peak party season is your main reason for visiting, choose September.
September or October?
September still feels like summer. Beaches are operating, the sea is warm, Mykonos Town is lively, and ferry connections remain strong.
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.
