Mangystau month by month: heat, wind and when people go

Mangystau, the desert region on Kazakhstan’s Caspian coast, has three seasons for travellers: a hot summer from June to August, two good windows in April–May and September–October, and a windy, cold winter. Inland near Bozzhyra, July averages 22 days of 35 °C or more out of 31. April and October each have 23–24 comfortable days, with highs of 15–30 °C and no strong wind.

These are ERA5 reanalysis values for the grid cell next to Bozzhyra, averaged over 16 years. November to February has no 35 °C days, so only the warm months are shown. For getting to Bozzhyra, permits and safety, see Bozzhyra and Mangystau. This page covers weather, daylight and demand by month.

Mangystau weather by month near Bozzhyra

The best months for long trips across the plateau are April, September and October. May is good in the first half and hot by the end.

Average high and low and average days or nights per month, ERA5, 2010–2025. A comfortable day has a high of 15–30 °C and maximum wind under 40 km/h. The verdict is our own reading of heat, cold and wind together.

The average gap between day and night near Bozzhyra in summer is 13–14 °C in ERA5. Sources quoted on our park page describe night drops of 20–30 degrees in the desert. The reanalysis averages smooth both the heat and the night chill, so individual nights can be sharper.

Coast or interior: two different heat levels

The coast is hot; the interior is very hot. Aktau averages 33.2 °C in July with about 11 days of 35 °C or more, while the point near Bozzhyra averages 37.1 °C with about 22. Aktau almost never reaches 40 °C; near Bozzhyra July has about 8 such days.

ERA5, 2010–2025, grid cells 43.75°N 51.25°E (Aktau) and 43.5°N 54.0°E (near Bozzhyra). The practical point: on a June–August trip, base yourself on the coast and make day trips inland with a pre-dawn start rather than camping on the plateau.

Hot days vary a lot from year to year: near Bozzhyra from 43 in 2013 to 80 in 2010, in Aktau from 5 to 58. The last three years were calmer than average, 52–56 days near Bozzhyra. Sixteen years is too short to call a trend. For heat safety in canyons and desert, including water and timing, see heat in canyons and deserts.

The two travel windows: April and September–October

Comfortable days peak in April (24), October (23) and September (20). July has about one; January and December none.

April and October differ in nights and daylight. April gives 13.4 hours of daylight and nights averaging 9 °C. October gives 11 hours and 6.7 °C, with about two frosty nights a month. Bozzhyra is about 300 km from Aktau each way, so in October a start before sunrise buys a useful margin of daylight. The Mangystau 3- and 5-day route outline shows how the stops fit together, and what to see in Mangystau region lists every site with its season. The base city is covered on Aktau, and day trips on day trips from Aktau.

Wind: a coastal and spring problem

Strong wind in Mangystau is mainly a coastal issue in the cold half of the year. Aktau has 2–3 days a month with wind of 40 km/h or more from December to April, and less than half a day a month in June–August.

In the grid cell near Bozzhyra, days with wind of 40 km/h or more barely occur in ERA5. Gusts of 60 km/h there are most common in March–April (5–6% of days) and May (4%). Reanalysis wind is averaged over a cell about 25 km across and can be stronger on the exposed cliff edge. For tents and drones, spring is therefore riskier than autumn, when 60 km/h gusts occur on 1–1.5% of days.

When people go: search demand

Foreign interest in Bozzhyra is growing fast. Worldwide searches for “bozzhyra” rose from 590 a month in October 2025 to 2,400 in August and September 2026, fourfold in under a year. Searches for “mangystau” reached 22,200 in June 2026.

Domestic demand has a clear season. Russian-language searches for Bozzhyra in Kazakhstan peaked at 8,100 in April 2025 and held at 5,400 through July–September, the hottest months on the plateau. September and October are as good as April for weather and draw a third to a half less search interest than the April peak. We have no monthly visitor counts to compare.

Hotels in the Mangystau resort zone ran at 38% room occupancy on average in 2025 and served 370,119 guests, according to the Bureau of National Statistics. Monthly occupancy is not published in the open tables, so we cannot compare it with the weather.

How we calculated

Weather. Daily maximum and minimum temperature, maximum wind and gusts at 10 m, daylight and sunshine duration, and precipitation from ERA5 through the Open-Meteo archive with an explicit models=era5, 1 January 2010 to 31 December 2025. Two points: Aktau (cell 43.75°N 51.25°E) and an inland point near Bozzhyra (requested 43.40°N 54.07°E, cell 43.5°N 54.0°E). Open-Meteo adjusts temperature to the point’s elevation. Shares of days are converted to days by multiplying by the month length.

Comfortable day: high from 15 to 30 °C inclusive and maximum wind under 40 km/h. The threshold is a choice; the CSV lets you recalculate with your own.

Demand. Ubersuggest, retrieved 9 November 2026: “bozzhyra” and “mangystau” worldwide; «бозжыра» and «мангистау» in Kazakhstan in Russian. These are searches, not trips.

Hotel occupancy. Bureau of National Statistics, accommodation activity for January–December 2025: table 26 by resort zone (63 properties, 370,119 guests, 38% room occupancy) and table 5 by region (426,818 guests, 34.9%).

Scripts and raw API responses are kept with the project. The monthly result is in the CSV file.
