Antalya (Turkish Riviera) weather in September

Antalya's forum consistently rates late September as close to ideal — warm days without July and August's peak heat, and a sea still warm enough for comfortable swimming. Regulars note humidity drops off noticeably as the month goes on, making the back half more comfortable than the first.

Regulars are specific that the last week of this month is the real sweet spot for using both the beach and unheated pools without the scorching heat that arrives later in summer, water warming appreciably between mid-month and the end of it. Our row backs that warm, still-mild read, 26.7C reading as a hot 28C, over 16.3C nights, with 44.9mm of rain across 5.1 days and humidity at 63 percent. Regulars are consistent early in the month can be genuinely hit or miss, some showers still possible, so visitors with flexible dates are advised to lean as late in the month as they can. The sea sits at a cool 21.1C, still on the brisk side for a long swim early on. The record: 12.3 hours of sun, a 13 kph wind and AQI 57.

Regulars are specific that this coast treats October as still summer rather than a shoulder season - hot enough at midday that walking around in the sun isn't comfortable - with the official season only ending on the 31st, after which hotels switch to a winter setup and close their waterslides. Our row backs the lingering heat, 27.8C reading as a real 28C, over 16.9C nights, with 50.9mm of rain across 4.3 days. Regulars are clear evenings do cool down enough to notice, especially sitting outside, so a light layer for dinner is worth packing even on a hot-feeling day. The sea stays warm and swimmable at 26.7C right through the month. The record: humidity 62 percent, 9.8 hours of sun, an 11.8 kph wind and AQI 44.

Antalya-forum threads asking for an honest opinion on August temperatures don't sugarcoat it: hotel displays regularly show 40C and up, with some accounts describing direct-sun readings as high as 50C, though that extreme is less common than the consistent mid-30s most days. Posters contrast it with July, which runs hot too but as a drier heat that's called more bearable than August's added humidity. The standing coping strategy: expect to adjust after a day or two, treat 11am to 4pm as shade-or-indoors time, and lean on hotel air conditioning for a break. Excursions are called a bad idea in this window entirely. Regulars who return every summer regardless call it hot but never genuinely unbearable. The record: 34.3C days feeling like a sticky 37C, 24.7C nights, essentially none at all, a 30.9C sea, humidity a relatively low 57 percent and 12.4 hours of sun.

July in Antalya is a heat you plan around rather than tolerate. Regulars give daily maxima of 32 to 34C with heatwaves pushing near 40 - our row says 35.7C, reading as 39C - and are careful to say those are shade figures, with the sun a different matter again, and the evenings staying very warm. Their verdict splits on what you came for. If the holiday is water-based it works: everywhere is air-conditioned, the sea is around 28C by midsummer, and a proper siesta in the middle of the day makes it manageable. If you came to sightsee, several say plainly they would not do July or August again. Rain is nil at 1.4mm. The record: 24.7C nights, humidity 48 percent and 13.5 hours of sun.
