Wetter in Almaty im September

September is the month locals on the forum call the most beautiful of the year in Almaty — warm, plenty of sun, neither hot nor cold, and late September still warm enough for a t-shirt through the day. The number worth noticing is the spread rather than the average: days run about 22°C but nights fall to around 9, so the light jacket regulars recommend is for the evening, not the afternoon. The broader window they give is April to October, with May and June their other favourites; from October the weather turns changeable in a New England sort of way.

Regulars call this squarely the hottest stretch of the year alongside August, dry heat that can push past 30C with a genuinely noticeable gap between standing in shade versus direct sun. Our row backs that hot, dry read, 32.4C reading as a hot 33C, over 19.2C nights, with 47.3mm of rain across 8.8 days and humidity down to 49 percent. Regulars are consistent the nearby mountains stay a popular escape from the city heat, Big Almaty Lake and the ski-resort-turned-summer-hiking areas both within easy day-trip reach. Sun protection and plenty of water are the standard advice for anyone spending real time outdoors at midday. The record: 12.7 hours of sun, a 9.8 kph wind and AQI 66.

The board's summer verdict is blunt - July and August are very, very hot, with talk of forty degrees in a bad week - and the months they actually recommend are May and June, inside a wider April to October window. Our row gives 30.5C by day, which still reads as 30C rather than worse, because the humidity column disagrees with the word regulars reach for: 49.6 percent at a dew point of 6.9C is dry air, and that dryness is why the nights fall all the way back to 17.4C. The escape is the one locals use, the mountains starting at the edge of the city and the resort above it at 2,260m, where a jacket earns its place on a windy afternoon. Rain is 62mm across 9.6 days. The record: 11.7 hours of sun and AQI 60.

June here is two climates stacked on top of each other, and regulars describe the gap rather than either end. The city can sit at 30C - our row reads 29.1C - while the cable car up to 3,200m finds snow still lying and air cold enough in the wind that they tell visitors to carry a light jacket, closed shoes and a hat, and to expect rain up there even on a fine day below. That vertical escape is the reason they recommend the mountain in summer at all. Down in the city the month is dry-feeling at 57 percent humidity with 72.6mm across 12.5 days. The record: 16.4C nights, 12 hours of sun inside 15.3 of daylight, and AQI 68.

May and early June are the months regulars put first for Almaty, and the range they quote - plus 25 to 30C from mid-April to early June - runs warmer than our row's 24.1C over 11.2C, which reads as 25C by day and 9C at night. What the month offers is both things at once: snow still up on the mountains at Shymbulak and Medeo, green and pleasant weather down in the city, and fewer people than the summer. The catch is water. Our row carries 144.5mm across 14.7 precipitation days, the wet end of the Almaty year, so half the month is showery. The 2.1cm of snow in the row is the Zailiysky Alatau inside the grid square rather than the streets. The record: 10.9 hours of sun and AQI 68.
