Summer in Kazakhstan has a split personality, and once you understand it, you can plan a near-perfect trip. Down on the steppe and in the cities it gets genuinely hot — the kind of dry, dusty heat that sends locals looking for shade by mid-afternoon. But drive an hour up into the Tian Shan and you are in cool green alpine air beside turquoise lakes with snow still on the peaks above. The whole game of a Kazakh summer is knowing when to go up, and this guide is built around that one idea.
Kazakhstan in summer (June to August) is hot and dry in the cities and on the steppe — Almaty regularly hits the low 30s°C and the southern deserts exceed 40°C — but the mountains stay cool and green, making them the place to be. Summer is peak season for the high lakes like Kolsai and Big Almaty Lake and for trekking, when the snow finally clears the passes. Come prepared for heat below and cool nights above.
Kazakhstan in summer at a glance
| Month | Character | Almaty temps (approx.) |
|---|---|---|
| June | Green and comfortable; wildflowers linger at altitude; long days | 16–28°C |
| July | Peak heat in cities and on the steppe; mountains at their best | 19–31°C |
| August | Hot and dry; prime trekking as passes are clear | 17–30°C |
Summer’s split personality
The single most useful thing to grasp about a Kazakh summer is the vertical dimension. Almaty at 800 metres bakes; the Big Almaty Lake basin at 2,500 metres, twenty kilometres away, is jacket weather in the evening. The mountains act as a natural air-conditioner, and locals have organised their summers around escaping upward for generations. Plan your trip the same way: sightsee in the cities in the cooler mornings and evenings, and spend the hot middle of the day — and ideally whole stretches of the trip — up high.
Summer weather, region by region
Kazakhstan is the ninth-largest country on earth, so “summer weather” means four different things depending on where you stand.
Almaty and the southeast: hot city, cool mountains
Almaty is the classic base, and it is warm to hot in summer — average July highs around 30–31°C, with heat waves pushing into the high 30s. But it sits right against the Tian Shan, so relief is always close: the mountains above the city typically sit around 20–25°C by day and cool to 10–15°C at night. The days are long, with around fifteen hours of daylight in June and July, which gives you time for an early hike and a late dinner.
Astana and the northern steppe: milder but wilder
The capital, Astana, sits far to the north on open steppe, and its summers are noticeably milder than Almaty’s — average July highs around 26–27°C — though heat waves can still spike into the high 30s. What defines an Astana summer is the sky: June and July are its rainiest months, with afternoon thunderstorms, and it is a famously windy city. Pack a light layer and something waterproof even in July.
Aktau, Mangystau and the deserts: extreme heat, warm sea
Out west on the Caspian, Aktau bakes but is moderated by the sea, with average highs around 30–31°C and Caspian water warm enough to swim in — roughly 23–24°C in July and August. Venture inland into the Mangystau deserts, or across the southern steppe toward Kyzylorda and Turkestan, and the mercury regularly tops 40°C with no shade to be found. The surreal chalk landscapes of Mangystau are spectacular, but summer is a brutal time to explore them; spring and autumn are far kinder.
The high mountains: your natural air-conditioning
Above roughly 2,000 metres, summer is the season Kazakhstan does best. Days are pleasantly warm, nights are cold, wildflowers linger into July, and the snow that seals the high country for most of the year has finally melted off the trails. If the heat below is the problem, the mountains are always the answer, and the beauty of Almaty is that the answer is only an hour away.
June, July or August: which summer month?
All three summer months are good, but they are not identical, and if your dates are flexible it is worth choosing deliberately.
June is my quiet favourite. The high country has usually opened up by mid-month, the meadows are still green and full of the last wildflowers, the waterfalls run full on snowmelt, and the cities are warm rather than scorching. The catch is that an unusually late snow year can keep the very highest passes closed into early July. July is the reliable heart of summer: the passes are clear, the days are longest, and every trail and lake is open — but it is also the hottest month in the cities and on the steppe, and the busiest, so book ahead and plan around the heat. August is much like July, still prime trekking weather, with the meadows drying to gold and the crowds easing slightly toward the end of the month; the southern deserts remain punishing. If you want green and quiet, lean June; if you want guaranteed access to every high route, lean July or August.
Escaping the heat above Almaty
You do not have to go far from the city to swap 32°C for 22°C. A few escapes are almost on Almaty’s doorstep.
Big Almaty Lake and beyond
The turquoise bowl of Big Almaty Lake, at about 2,500 metres and only twenty kilometres from the city, is the classic half-day escape — ringed by peaks over 4,000 metres and at its most vivid blue in summer. From the lake, the fit and acclimatised can push on up to the Kosmostantsiya observatory at around 3,300 metres, or tackle Big Almaty Peak at roughly 3,680 metres. Even if you just sit by the water with a flask of tea, the temperature drop alone is worth the drive.
Shymbulak, Medeu and Turgen
The Medeu skating rink and the Shymbulak ski resort, both a short trip above Almaty, reinvent themselves in summer as cool-air escapes with cable cars, ridge walks, and views. Further east, the Turgen gorge offers waterfalls and forest walks in the shade. None of these require serious mountaineering — they are simply how Almaty keeps cool.
Kazakhstan’s best summer lakes
Summer is lake season, and Kazakhstan’s are exceptional. The high alpine lakes only become fully accessible now, once the snow has cleared the access roads.
The Kolsai Lakes
The three Kolsai Lakes, strung up a forested valley in the Tian Shan, are the “pearls” of southeast Kazakhstan. The lowest sits at around 1,000 metres and is reachable by road; the second, at about 2,500 metres, is a beautiful three-hour hike up through spruce forest; the third, higher still near 2,700 metres, is for committed trekkers. The best window is June to September, and even in high summer the nights up here are cold, so bring warm layers. It is roughly 300 kilometres from Almaty via the gateway village of Saty, and there are lakeside yurt camps if you want to stay over.
Lake Kaindy and its sunken forest
A short but rough drive from the Kolsai valley lies one of Kazakhstan’s most photographed sights: Lake Kaindy, at around 2,000 metres, where the bleached trunks of a spruce forest spear up out of blue-green water. The lake was created by a landslide during a huge earthquake in 1911, which dammed the valley and drowned the trees — their submerged, preserved trunks are the eerie result. Our guide to Lake Kaindy covers how to combine it with the Kolsai Lakes on one trip.
Burabay, Alakol and Balkhash
Summer is also the season for Kazakhstan’s swimming and resort lakes. In the north, Burabay (Borovoe) — often called the “Switzerland of Kazakhstan” for its pine-clad rocks and clear water — hits peak visitation now. Far to the east, Lake Alakol draws Kazakhs for its mineral-rich “healing” waters, while vast Lake Balkhash is the country’s go-to for a proper beach day. Our guide to lakes in Kazakhstan rounds them all up.
Best summer hikes and treks
If you have come to walk, summer is your season — but the calendar is tighter than you might expect.
When the passes clear
The high trekking season runs roughly from mid-June to mid-September, with July and August the reliable peak once the snow has melted off the high passes and the days are at their longest. Earlier than mid-June and you risk snow and washed-out trails; later than September and winter starts closing back in.
Day hikes from Almaty
Almaty is one of the great trailhead cities. Popular day walks include the climb to Furmanov Peak, an eleven-kilometre round trip best started at six or seven in the morning, and the forest walk to the Butakovka waterfall, which is fullest in June during the snowmelt. A word of caution I take seriously: afternoon clouds and lightning are common on the peaks after about two in the afternoon in July and August, so start early and be off the tops by early afternoon. Our guide to hiking in Kazakhstan has routes for every level.
The multi-day Kolsai-to-Kaindy route
For those wanting more than a day walk, the trek over the pass from the Kolsai Lakes to Lake Kaindy is a classic, taking you through high pasture and forest with an overnight in between. It is moderately demanding and best attempted in the July–August window when the pass is clear.
Charyn Canyon in summer: go early
Charyn Canyon is a must on almost any Kazakhstan trip, but in summer it demands respect. The canyon floor can reach 40°C in July and August — and feel closer to 50°C at midday — running a good 5 to 10°C hotter than the rim, with almost no shade among the red rock towers. The strategy is simple: arrive by ten in the morning, walk the Valley of Castles while it is still bearable, and carry two to three litres of water per person. It is around 200 kilometres and a three-to-four-hour drive from Almaty, so an early start does double duty. See our Charyn Canyon guide for the full picture and our roundup of day trips from Almaty for combining it with the lakes.
Summer culture: jailau, yurts and horses
Summer is when Kazakhstan’s nomadic heritage comes closest to the surface. Traditionally, herders move their animals up to the jailau — the high summer pastures — and it remains the season to see the felt yurt (itself recognised by UNESCO as intangible cultural heritage) pitched on green highland steppe. Summer festivals bring out horseback games such as kokpar and baiga, and a growing number of yurt camps let visitors stay overnight in the mountains and on the steppe. It is the most atmospheric time to connect with the culture our Kazakh culture guide explores in depth.
Where to sleep in the mountains
One of the pleasures of a Kazakh summer is that you do not have to retreat to a city hotel every night. In the Kolsai valley and around Saty, family guesthouses offer simple, warm hospitality and home-cooked meals, and there are lakeside yurt camps where you can wake up beside the water — an experience worth the modest cost and the cold night. Higher up, wild camping is possible for the properly equipped, though nights at 2,500 metres are cold even in July, so a good sleeping bag is essential. In the northern lake districts around Burabay, and at the Caspian resorts near Aktau, you will find more conventional hotels and holiday accommodation. Wherever you stay in the high country, book ahead in peak summer and bring more warm clothing than the daytime heat suggests you will need. Our guide to where to stay in Kazakhstan covers the options region by region.
Staying safe in the steppe and desert heat
The mountains are forgiving; the lowland heat is not. On the steppe and in the deserts, summer temperatures above 40°C are genuinely dangerous if you are unprepared. Carry far more water than you think you need, cover up against the sun rather than stripping off, avoid strenuous activity in the midday hours, and do not wander into remote desert areas like inland Mangystau without a guide, a vehicle in good order, and plenty of supplies. Even around the lakes, be aware that some areas near the borders with China and Kyrgyzstan are border zones, so carry your original passport for checkpoints.
Practical summer tips
A few final things smooth out a summer trip.
Long days, storms and mosquitoes
The long daylight is a gift — plan to use the cool early mornings and long evenings and rest through the hot afternoons. Watch for afternoon thunderstorms in the mountains and the north. And near lakes and wetlands, especially in the evenings, mosquitoes can be a nuisance, so pack repellent.
Peak season: book ahead
Summer is peak domestic season, so the popular spots — Kolsai, Kaindy, Big Almaty Lake, Burabay — get busy, and transport and yurt stays to the harder-to-reach lakes should be arranged in advance rather than on the day. Our Kazakhstan itinerary guide helps you sequence it all.
What to pack
Pack for two climates at once: light, breathable clothing, a sun hat, and sunglasses for the heat below, plus a fleece and a waterproof shell for cool mountain nights and sudden storms up high. Sturdy walking shoes, high-factor sunscreen, and a refillable water bottle round it out.

Frequently asked questions
Is summer a good time to visit Kazakhstan?
Yes, particularly for the mountains and lakes, which are only fully accessible in summer once the snow clears. The trade-off is real heat in the cities and on the steppe, and searing temperatures in the southern deserts. The trick is to base around the cooler mountains, sightsee in the mornings and evenings, and save desert regions for spring or autumn.
How hot does Kazakhstan get in summer?
Almaty averages highs around 30–31°C in July, with heat waves into the high 30s, while the southern steppe and deserts regularly exceed 40°C. The capital Astana is milder at around 26–27°C. Up in the mountains, however, daytime temperatures sit around a comfortable 20–25°C and nights are cold, which is why locals head uphill.
Can you swim in the Kolsai Lakes?
You can, but they are cold — these are high alpine lakes fed by snowmelt, so even in August the water is bracing and the nights are chilly. Most visitors come for the scenery and the hiking rather than a swim. For proper swimming, Kazakhstan’s warmer lakes are Alakol and Balkhash, and the Caspian at Aktau reaches a comfortable 23–24°C.
How do you get to the Kolsai Lakes and Lake Kaindy from Almaty?
Both lie around 300 kilometres southeast of Almaty via the village of Saty, which is the gateway. There is no easy public transport, so most people go by organised tour or hired car, and the final stretch to Lake Kaindy is a rough road best done in a high-clearance vehicle. Many visitors combine both lakes over a two-day trip with a night in a Saty guesthouse or a lakeside yurt.
When is the best time for trekking in Kazakhstan?
Mid-June to mid-September, with July and August the most reliable, because that is when the snow has melted off the high passes and daylight is longest. Start mountain hikes early to be off the peaks before the common afternoon thunderstorms, and carry warm layers even in summer, as high-altitude nights are cold year-round.
What is there to do in Almaty in summer?
Plenty, and much of it beats the heat. Sightsee in the cooler mornings and evenings — parks, the Green Bazaar, Kok-Tobe hill — then head up to Medeu, Shymbulak, or Big Almaty Lake in the day when the city is hottest. Almaty is also the launchpad for day trips to Charyn Canyon and the Kolsai and Kaindy lakes, making it the natural base for a summer trip.
Are there mosquitoes in Kazakhstan in summer?
Around lakes, rivers, and wetlands they can be a nuisance, particularly in the evenings and in the northern lake districts, so pack repellent if your trip includes lakeside stays. In the dry cities and on the open steppe they are much less of an issue. It is a minor annoyance rather than a health concern for most travellers.
Is Charyn Canyon worth visiting in summer?
Absolutely, but go early. The canyon is spectacular year-round, yet in July and August the floor can hit 40°C or more with no shade, so arrive by mid-morning, walk the Valley of Castles before the worst heat, and carry two to three litres of water per person. Combining it with the cooler Kolsai and Kaindy lakes over a couple of days makes for one of Kazakhstan’s finest summer trips.
Final thoughts
A Kazakh summer rewards travellers who read the vertical map. Accept that the cities and steppe will be hot, treat the mountains as your refuge, and time your trip for the lakes and the trekking that only open up now. Start your days early, carry water, book the popular lakes ahead, and keep a fleece in the pack for those cold nights at 2,500 metres. Do that and you will get the best of both Kazakhstans in one trip — the warm, buzzing cities and the cool, wild high country above them.
