Traveller notes on Çeşme in September

Çeşme's forum calls early September still properly hot, cooling only slightly by the end of the month, with evenings starting to feel noticeably fresher. Regulars flag wind as the local wildcard — the Aegean coast runs windier than Turkey's Mediterranean side, with reports ranging from a strong 40 km/h blow to barely noticeable, depending on the week. The town itself empties out once local schools restart in mid-September.

Other months in Çeşme

Regulars are specific this counts as excellent beach weather without the much higher heat of July and August, a real step up from a showery April into a month that's genuinely much drier, just occasional light, scattered rain rather than anything resembling a rainy season. Our row backs that mild, genuinely dry read, 24.7C over 15.4C nights feeling 14C, with rain minimal at 10.2mm across 2.7 days and humidity at 68 percent. Regulars are consistent this coast stays warm and pleasant without peak-summer intensity, a genuinely good window for beach time before the crowds and heat of high season arrive. The sea sits at a cool 18.3C. The record: 12.6 hours of sun, a 23.8 kph wind and AQI 54.

Regulars call this generally pleasant, most days still good enough for some beach time, while flagging that this stretch of Aegean coast, north of Kusadasi, gets increasingly blustery and less comfortable from late September onward. Our row backs the mild-but-windy read, 23.8C over 14.7C nights, with 30mm of rain across 3.6 days and a real 26.2 kph wind. One visitor's report of two straight windy, rainy days shows the exception rather than the rule, since most regulars describe the month overall as good. The sea sits at 22.4C, still comfortable for a swim. The record: humidity 72 percent, 9.8 hours of sun and AQI 45.

Mid-June to mid-September is summer on this coast and July sits in the middle of it - hot throughout, with regulars pointing anyone who wants less of it at the first fortnight of June or the last of September. Our row gives 31.3C at 60 percent humidity with 0.3mm of rain and no precipitation days at all. The Aegean wind is the daily variable rather than the weekly one: at 29.3 kph it is why the heat stays tolerable, and the advice is to check its direction each morning and choose a sheltered beach accordingly - Alacati next door is a windsurfing town for the same reason. Come early or late in the day: the beaches fill and the loungers run out, and Alacati is the priciest town in Turkey in season. The record: 22.9C nights, 13.3 hours of sun, a 23.5C sea and AQI 64.

Cesme regulars treat the wind as the reason to choose this stretch of Aegean coast over the rest of it in August: it is almost always blowing, rarely under ten knots, and it keeps a month that would otherwise be punishing down to something pleasant. Our row's 28.7 kph is the same northerly the Greek islands opposite call the meltemi, coming down the bay from the north, and it is why 31.1C only reads as 32C at 63 percent humidity. Rain does not exist: 0.7mm across 0.2 precipitation days. Alacati next door is the windsurfing centre for exactly this reason, shallow bright water with dependable wind from spring through autumn. The record: 22.7C nights, 12.6 hours of sun, a 24.7C sea and AQI 57.
