12.09.2025 - 19:50

Marmaris is located in southwestern Turkey, where the Aegean and Mediterranean climates converge, and attracts holidaymakers for most of the year with its sunny weather and clear sea. Although the summer season generally lasts from June to mid-September, the autumn months are also a very appealing time for Marmaris. With the summer crowds thinning out, the weather remaining favourable for a long time, and sea temperatures gradually beginning to drop, you may be wondering whether you can swim in the sea in Marmaris during autumn.

So, can you swim in Marmaris in Autumn? What are the best beaches to swim in Marmaris? Let's explore the beauty of Marmaris together!

Climate Conditions and Autumn in Marmaris

Marmaris has a typical Mediterranean climate. This means that summers are long, hot and dry, while winters are mild and rainy. Autumn is the most enjoyable time of this transitional period. It is still possible to feel the summer heat during the day, especially in September and October. Although the nights start to cool down, you can still enjoy the sea during the day. In November, temperatures drop significantly and the chance of rain increases.

The geographical structure of the region also affects the climate. Marmaris is surrounded by forested mountains, which balance the air temperature, breaking the extreme heat and also increasing the humidity. This feature ensures that sea water temperatures remain high for a long time, especially in September.

Is it Possible to Swim in the Sea in Marmaris in Autumn?

It is definitely possible to swim in the sea in Marmaris in autumn. The sea retains the warmth it has accumulated throughout the summer, particularly in September. There are still plenty of warm days for swimming in October. By November, the sea water cools down, but it is still possible to enjoy the sea on sunny days, especially in the first half of the month.

The most important factor determining the experience of swimming during this period is personal comfort threshold. Some people find 22–23 degrees comfortable enough for swimming, while others may find this temperature cool. Therefore, swimming in Marmaris in autumn largely depends on the individual's tolerance for cold water.

Temperatures in Marmaris in September, October and November

September: This is the month when the days of summer linger on. Daytime air temperatures are generally between 28–31°C, while night-time temperatures are around 20–22°C. Sea water temperatures are around 26–27°C. Therefore, September is the ideal time for those who want to swim in the sea in Marmaris in autumn.

October: Air temperatures drop to 22–27°C during the day and range between 14–18°C at night. The average seawater temperature is around 24–25°C. The first half of the month in particular still offers quite comfortable swimming conditions. However, the second half becomes noticeably cooler.

November: The sea water cools down to 20–22°C. The air temperature is 15–20°C during the day and cooler at night. If you encounter warm, windless weather in the first days of November, it is still possible to swim. However, as the month progresses, increased wind and rainfall make swimming more difficult.

The Best Times to Swim in Marmaris

Although the sun's rays are weaker in autumn than in summer, the water temperature feels more comfortable at midday. The sea can be cool in the early morning hours, and the wind starts to pick up in the late afternoon. Therefore, the best times to swim in Marmaris in autumn are generally between 10:00 and 12:00 and between 14:00 and 17:00 in the afternoon.

At these times, the sun is high enough in the sky and the sea water is at its warmest. It is also important to pay attention to the wind conditions, as the sea can become less enjoyable when the wind picks up.
