Santorini in September.
The September Sweet Spot: Why Visit Now?
For many travelers, September is the best overall month to visit Greece. The intense heat of midsummer eases, the sea is at its most inviting, and most of the country remains fully open and lively. It is especially appealing if you want a classic Greek holiday that combines swimming, island hopping, outdoor dining, and sightseeing without the peak pressure of August crowds. While August can feel like a marathon of endurance against the heat and the masses, September offers a more relaxed, adult-oriented atmosphere where the pace of life finally begins to match the scenery.
September Weather: A Regional Breakdown
September weather in Greece is generally warm, sunny, and far more comfortable than July or August, though it is not uniform across the country. You can expect long, sunny stretches, but the experience varies by region.
- Athens and the Mainland: Temperatures remain summery, hovering around 28°C to 30°C. It is much more manageable for sightseeing than midsummer, though the Acropolis can still feel very hot at midday.
- The Cyclades (Santorini, Mykonos, Naxos): These islands are usually warm and breezy. While the strongest Meltemi winds of July and August ease, windy days still happen, which is great for windsurfers but can occasionally make ferry crossings a bit bumpy.
- Crete and the Dodecanese (Rhodes): Being further south, these regions offer the hottest late-season beach weather. Crete, in particular, holds onto high summer temperatures well into the month.
- The Ionian Islands (Corfu, Lefkada): These islands are greener and can be more humid. While mostly sunny, the chance of a brief, refreshing rain shower increases toward the end of the month.
- Sea Temperatures: This is a major highlight. Sea temperatures in September are typically among the warmest of the year, as the water has spent all summer absorbing the sun’s heat.
September vs. Other Months
August vs. September: August is the busiest, hottest, and most expensive month. By September, the “family rush” ends as schools resume, and daytime temperatures become comfortable for walking. You get the same warm water as August but with noticeably thinner crowds, especially in the latter half of the month.
September vs. October: October is a great budget month, but it is a period of transition. By mid-October, many seasonal businesses on smaller islands begin to close, and ferry frequencies drop significantly. September feels like a continuation of summer with everything fully operational, whereas October can start to feel like the end of the season.
Early September vs. Late September
The experience of traveling in the first week of the month can be quite different from the last.
- Early September: Still feels very much like high season. The weather is hotter, the islands are busier, and the summer party vibe in Mykonos or Ios is still in full swing.
- Late September: The atmosphere is much quieter. Prices for accommodation begin to soften, and while the weather is generally excellent, you might encounter the occasional breezy or overcast day. This is the ideal time for those seeking peace and value.
Who is September Best For?
Best For:
- Couples and Honeymooners: The atmosphere is more sophisticated and romantic once the peak family crowds depart.
- Swimmers and Divers: The water is at its absolute best.
- Sightseers: Exploring ancient ruins is far more pleasant when you aren’t fighting 35°C heat.
- Food and Wine Lovers: The grape harvest (vendema) makes this a fascinating time for winery visits.
Who Should Skip It:
- Peak Party Seekers: If you want the absolute peak clubbing energy of Mykonos, late July or August is still the better choice.
- Strict Budget Travelers: While cheaper than August, early September is still considered high season for pricing in spots like Santorini. Early May or October offers more radical savings.
Top Destinations & What to Expect
Athens: The capital is far more comfortable than in midsummer. You can explore the historic neighborhoods of Plaka and Psirri without the intense humidity of August. However, major sights can still be crowded, so I recommend visiting the Acropolis early in the morning or late in the afternoon.
Santorini: This is my favorite month for the caldera. The views are spectacular, and the water is perfect for Santorini volcano boat tours. For top-tier caldera-view hotels, I still recommend booking well in advance, though midrange and non-caldera options are easier to find than in August.
Mykonos: A more refined experience. Reservations at top beach clubs and dinner spots are easier to secure than in August, but the most popular venues still book out, especially on weekends. Mykonos tours remain popular, and the sea is still ideal for swimming.
Mykonos is idyllic in September.
Crete: September is one of the best months for the Samaria Gorge, provided the park remains open and weather conditions allow access. The southern coast of Crete remains a sun-drenched haven. Crete is great for families this month.
Naxos & Paros: These are the best for a balance of beaches and local food. The interior villages are much more pleasant to explore in the cooler September air. Like Naxos, the landscape here is drier than in the spring, but the golden hues have their own beauty. Naxos remains the top pick for a relaxed family beach holiday.
Rhodes: The Dodecanese islands are a superb choice for late-season sun. The primary pro is guaranteed warm and sunny weather. A Rhodes boat tour is a fantastic way to see the coastline in the warm September light.
Corfu & The Ionians: The humidity levels drop, making the elegant Old Town of Corfu a joy to walk through. The lush greenery is a nice contrast to the drier Cyclades, though late-month showers do happen.

Smaller Islands: In the Cyclades, Milos and Folegandros are spectacular, offering dramatic scenery and wonderful swimming spots.
Mainland Greece: September is an ideal month for a road trip through the Peloponnese or to visit Delphi and Meteora. The Athens Riviera is wonderful in September.
Culture & Events
September is a rich month for local culture. Look out for early-autumn events such as the Armata celebrations in Spetses, Aegina’s pistachio festival, and the buildup to the Athens International Film Festival. Exact dates vary by year, so check local listings a few weeks before you travel. In wine regions like Santorini and Crete, the grape harvest is in full swing, which can be an especially interesting time for winery visits.
Practical Planning Tips
- Packing: Bring standard summer clothing but add a light jacket, sweater, or pashmina for ferry decks and the occasional breezy evening.
- Logistics: Most of Greece is still firmly in season, but some smaller-island businesses and a few ferry frequencies may begin to taper off in the final week of the month.
- Booking: While the shutdown hasn’t started, don’t assume the islands will be empty. Popular boutique hotels in Oia or Mykonos Town still see high demand throughout the month.
Frequently Asked Questions
Is September too late for Greek island hopping?
Not at all. In fact, it’s one of the best times. Ferry schedules are still frequent, and all major routes are operational. It is much easier to hop between islands when the ports are less chaotic than they are in August.
Which islands stay warmest in late September?
Crete and Rhodes are your best bets for late-season heat. Being the southernmost major islands, they maintain summer temperatures longer than the northern Aegean or Ionian islands.
Do beach clubs start closing in September?
Most beach clubs on popular islands like Mykonos, Santorini, and Paros stay open until the end of September or even early October. However, they may stop hosting big-name international DJs after the first or second week of the month.
Is it a good time for a family trip?
If your children aren’t yet in school or you have a flexible schedule, September is fantastic. The water is safe and warm for kids, and the heat is much less intense for toddlers. Naxos and Crete are particularly great for families this month.
Is late September still good for swimming?
Yes. The sea is warmer in late September than it is in June. While the air might feel slightly crisper in the evenings, the water remains very comfortable for swimming and snorkeling.
