Weather in Lemnos in September
September is late summer in Lemnos: warm and mostly dry. Expect highs of about 25°C / 77°F and overnight lows near 19°C / 66°F. Expect just 2 rainy days in a typical September. The sea averages about 23°C / 73°F, pleasant for a swim. Lemnos is a low, volcanic island in the north Aegean, with open landscapes and few trees to block the wind. The first autumn storms can arrive, usually as short, sharp showers between long spells of sunshine. Daylight lasts about 12½ hours. Pack summer clothes, a light layer for the evenings and good sun protection. When the wind picks up, a light windproof layer is handy for evenings by the water. The light is softer than in summer, which makes it a lovely time for photos and walks. The weather can change from one week to the next, so pack for both warm and cool days. It's comfortable to be out all day, though the midday sun is still strong.
Swimming in Lemnos in September
September is a great month for swimming in Lemnos, with water temperatures around 23°C / 73°F. Swimming is still good, although the sea has cooled since August. When the meltemi blows, north-facing beaches get rough, so head for sheltered bays on the south side. Quieter coves around the coast are often just as beautiful as the famous beaches. Beach bars and sunbeds are open, with more space than in July and August.
Crowds & Prices in Lemnos in September
September is a shoulder month in Lemnos, busy enough to feel lively but well below the summer peak. Prices are noticeably lower than in high summer, and there's more choice of rooms. Staying slightly outside the main town usually means better value and more space. Early mornings and late afternoons are the quietest times at popular sights. You can often book at short notice, except around holidays.
What's Open in Lemnos in September
In September, ferries from Lavrio and Kavala to Lemnos run often, with extra fast boats in the peak season. The island also has an airport with flights from Athens. It's the full season, so hotels, restaurants, beach bars and excursions are all running. Archaeological sites and museums are on their longer summer hours. Boat trips and excursions run regularly, weather permitting.
Festivals & Holidays in Lemnos in September
September is harvest time, with grapes picked for wine in many areas and village feasts on 8 September for the Nativity of the Virgin. Late-summer village festivals continue into September, and the grape harvest gets underway. In Lemnos, as across Greece, these traditions are very much alive. It's a good time to see traditions that have nothing to do with tourism, from harvests to name days.
Is September a Good Time to Visit Lemnos?

The only caveat is that a few seasonal businesses may be closed at the very start or end of the season.
Frequently Asked Questions
What time does the sun set in Lemnos in September?
Through September, sunset in Lemnos moves from around 7:55 pm to around 7:05 pm in Greek local time, as the evenings get shorter. In mid-September, expect it at around 7:30 pm. Evenings cool quickly after sunset, so bring a layer.
Is it still hot in Lemnos in September?
Yes, especially in the first half of the month. September usually stays warm and sunny, and the sea is still warm from the summer. The meltemi tends to ease, nights become more comfortable, and the first autumn showers sometimes arrive late in the month, although rain is still uncommon.
Can I visit the Pachies Ammoudies sand dunes in September?
Yes, but go early or late in the day. September is hot, and there's often little shade, so bring water and sun protection. They're in the north of the island, near Gomati.
Do I need a car on Lemnos in September?
It's the best way to explore. Lemnos is spread out, and buses mainly link Myrina with the busiest beaches and villages, so a hire car lets you reach quieter corners. In September, book early, as rental cars can sell out.
Is September or October better for visiting Lemnos?
September, if you want swimming and everything open. October is quieter and cheaper, and the sea often stays pleasant early in the month, but the weather becomes more changeable and many seasonal hotels, tavernas and boat trips wind down as the month goes on.
