Is the sea warm enough for swimming in Antalya and Lara in summer, late September, and early October?

On October 5, 2026, visitors reported warm daytime weather and said they had swum in the sea. Wind picked up from lunchtime, and jackets were needed for a walk along the waterfront.

A late-September on-the-ground update reports daytime heat of about 30–32°C and sea water that feels bath-warm. Based on these conditions, swimming should still be comfortable in the very beginning of October.

An early-September on-the-ground update reports a temporary drop in sea temperature: entering the water felt chilly in the morning and only somewhat better after lunch, though still not comfortable for long swims. Several days of northerly wind or a cold current were suggested as possible causes.

A traveler from the Urals swam in Aspendos in early November: the water was cool but swimmable (comparable to summer in Ural lakes), a hoodie was needed in the evenings. Very few people around — sometimes they had the beach to themselves. The beach closes for the winter season shortly after early November.

Another regular visitor, who has been coming to Avsallar only in October for five years, confirms that from October 17 conditions there are great and the sea is warm.

For early October (1st–10th), one traveler notes that on cloudy days air is around 24–26°C and the sea about 24–25°C — fine for sunbathing, but a windbreaker is needed after sunset. Unheated outdoor pools stay cold and don't warm up.

Another traveler calls this the 'velvet season': daytime around 27–28°C with the most comfortable sea, water can reach up to 28°C, but nights are cool at around 14–15°C.

Travelers who stayed from September 30 to October 21 report the sea stays warm (up to 27.5°C in early October), cooling to about 26–26.5°C by mid-month. There's no more heat, which is comfortable, but a light jacket or shawl is needed after 22:00 in the evenings.

A traveler who visited October 15–21 reports great daytime weather with warm sea, though evenings called for a shirt or hoodie. Friends who stayed longer noted the weather worsened slightly after October 21.

By early July, the sea in Antalya is usually fully warm for swimming at around 28–29°C, and the water is often clearest in the morning. Lara Beach has a sandy entry, so it’s a common choice for families and for travelers who prefer to avoid pebbles.

Compared with Bodrum, Antalya’s sea is usually noticeably warmer at this time of year. In early to mid-July, water here is commonly around 28–29°C, while the Aegean can feel much cooler because of currents and wind.

In early August, the main issue in Antalya is usually not cold water but intense heat. Sea temperature is often around 29–30°C and daytime air temperatures can reach 33–38°C, so the most comfortable beach hours are usually before 11:00 and after 16:00.

By late June, the sea in Antalya is usually already warmed up to about 25–27°C, with daytime air temperatures around 30–34°C. If you arrive early and need to wait somewhere, Lara Beach or Konyaaltı Beach are practical choices because they have cafés, loungers, and showers.

In early October, the sea in Antalya is usually still warm enough for swimming, most often around 25–27°C, and daytime weather remains summery at roughly 26–31°C. For most travelers, it is still a good beach season, especially in the first half of the month.

Late September is usually one of the most comfortable times in Antalya: the sea is still warm at around 27–28°C, while the heat is milder at roughly 28–32°C during the day. It’s one of the best periods for first-time visitors who want both beach time and sightseeing without peak summer heat.
