Visiting Greece In September: Everything You Need To Know

Here’s everything you need to know about visiting Greece in September — from the weather and prices to how busy it gets and the best things to do.

Greece Weather in September

September is one of the best months to visit Greece—summer warmth begins to ease, the sea stays inviting, and the days are still long.

• Daytime highs typically range from 68–82 °F (20–28 °C) depending on region.
• On the islands and southern coast you might still get to 80–88 °F (26–31 °C) during sun‑filled afternoons.
• Nighttime lows tend to fall into the 60s °F (10–17 °C) range — comfortable, but bring a light jacket for evenings.
• Sea temperatures remain warm and very swim‑friendly—typically around 73–77 °F (23–25 °C).
• Rain is still fairly minimal in many coastal and island locations, making outdoor plans more reliable.

Greece Sunrise & Sunset in September

With summer winding down, the daylight hours begin to shorten—but you’ll still have plenty of time to explore, relax and soak in views.

• In early September you’ll enjoy about 12+ hours of daylight, tapering slightly toward the end of the month.
• Typical sunrise times shift from around ~6:30‑7:00 a.m., and sunset times move from ~8:00‑8:15 p.m. toward later in the month.
• That daylight still gives you ample room for morning beach or city exploration, afternoon break, and evening dinner by the sea.

September Is Shoulder Season (with Highs) in Greece

Here’s how tourism demand and pricing tend to behave in Greece during September—and how that works for you.

• September often falls into the shoulder season—you might see slightly fewer visitors than peak summer months, especially later in the month.
• Travel value: Because it’s not quite peak summer, you may find better deals on flights, hotels and ferries compared with July/August.
• Crowds: Popular islands and city centres still see activity, but overall the pace tends to ease up and you’ll often get more breathing room.
• A note: The earlier part of September may still feel very much like summer—warm, lively, and busy—so if you prefer a quieter trip aim for mid‑ to late‑September.
• Booking tip: To lock in the best value and selection, book your accommodation and transport in advance — especially for islands.

Best Things To Do in Greece in September

September is a really smart month for combining great weather with more relaxed travel. Here are the top things to do — and why this month works for them:

• Beach & island time – With warm sea temps and fewer summer crowds, beaches and islands shine in September.
• Historical sites & cities – The slightly cooler days make visiting places like Athens, Delphi or the Peloponnese more comfortable than peak summer.
• Island‑hopping & discovery – Ferries are active, and you’ll find islands like Crete, Santorini or the lesser‑visited spots with a bit more space.
• Sunset dinners & al‑fresco evenings – Evenings are warm and enjoyable, perfect for terrace dining or a stroll by the water.
• Nature & landscape exploration – The heat has eased, and the countryside often looks great — good timing for drives, rural visits or hiking in milder conditions.
• Value trips – Because you avoid the highest summer demand, you may enjoy better accommodation value or more flexibility in choices.
