Yakutsk is a city where the temperature range exceeds a hundred degrees. In winter it's minus fifty here, while in summer the air heats up to 35°C and beyond. And the swimming season is one of the shortest in the country.

For someone from central Russia, it's hard to believe that anyone swims in Yakutsk at all. The city is associated with permafrost, ice fog and frost-coated eyelashes. But every July, Yakutsk gets a heatwave that makes you want to dive into the water just as much as in Krasnodar, only there are far fewer places ready to welcome a swimmer. And the window when swimming is possible at all is about two months a year.

A City on Permafrost With Tropical Heat

Yakutsk lies on the 62nd parallel, roughly the same latitude as Petrozavodsk. But its climate has nothing in common with that city's. Here it's sharply continental: the city is thousands of kilometres of land away from the oceans, and in winter the powerful Siberian High dominates over Yakutia.

The result is the most extreme temperature swing on the planet. The lowest temperature ever recorded at Yakutsk's weather station is −64.4°C (February 1891), and the highest 38.4°C (July 2011). That's a difference of almost 103 degrees. No other major city in the world can boast of (or complain about) such a range.

Beneath the city lies permafrost 200–250 metres thick. In summer, the top layer of soil thaws to a depth of two to three metres, then freezes again in autumn. Buildings stand on piles, pipes run above ground, and pavements sink and heave by turns.

What Summer Is Like in Yakutsk

Winter in Yakutsk lasts about seven months, from October to April. Snow lies on the ground until early May. The ice on the Lena usually breaks up in mid-May, and it's always an event: a powerful ice drift, with rising water and flooding.

After that, everything happens fast. Spring is more of a formality: it takes three to four weeks to go from zero at the start of May to 20°C by the end of the month, and the city leaps straight from winter into summer.

According to weather station data (1991–2020 norms), average daytime temperatures in the summer months look like this:

  • June: an average high of 23°C, with nights at 10°C. The air warms up quickly, but the nights are still cool. Lakes and rivers are only just recovering from winter.

  • July: an average high of 26°C, with nights at 13°C. This is the warmest month: daytime temperatures regularly climb to 30–35°C, and higher on some days. The heat is dry, with little rain.

  • August: an average high of 22°C, with nights at 9°C. From the second half of the month, it's noticeably cooler, and evenings can be 12–15°C. By the end of August, summer in Yakutsk is essentially over.

Annual rainfall is just 235 mm (compared with about 700 mm in Moscow). There's little rain and the air is dry. But in July and August, almost every year brings haze from wildfires: Yakutia's forests burn regularly, and smoke sometimes hangs over the city for weeks.

White Nights, Yakutsk-Style

One of the less obvious features of summer in Yakutsk is the white nights. The city lies at 62° north, and in June and July it practically never gets dark. Around the summer solstice (June 21), the days last almost 20 hours, about 19 hours and 44 minutes, and the rest of the time is bright twilight in which you can read outdoors.

The white nights here last about two months, from late May to late July. They're noticeably brighter than St Petersburg's: the sky isn't just light, it's almost daylight.

In winter it's the opposite: in December, the days shrink to just over five hours, and the sun barely rises above the horizon, with temperatures approaching minus forty.

Where to Swim: A Beach on a Side Channel and Oxbow Lakes

Yakutsk stands on the left bank of the Lena, one of the world's great rivers. The main channel isn't suitable for swimming: the current is strong, and even in July the water is cool (the river is fed mainly by snowmelt, and its basin lies in the permafrost zone).

But the main city beach, in the 202nd microdistrict, is on the city's side channel of the Lena, where the current is gentler. On hot days, around 10,000 people a day come here. The beach is supervised, with lifeguards on duty, and in 2026 it was extended by another 420 metres.

On top of that, there are more than a hundred lakes within the city limits. Most of them are oxbow lakes, former channels of the Lena cut off from the main flow. The best known are Tyoploye, Saysary, Taloye, Sergelyakh and Khatyng-Yuryakh. Small and shallow, they warm up faster than the river, but few of them have officially equipped swimming areas, and Rospotrebnadzor, Russia's consumer health watchdog, regularly tests their water.

Just a few years ago, the situation with official beaches was dire.

In 2021, when the city sweltered in temperatures of up to 35°C for two weeks, Rossiyskaya Gazeta reported that Yakutsk had not a single approved place to swim: the beach in the 202nd microdistrict only officially opened on July 11, by which time it had started raining. Things have improved noticeably since then: in recent years, the city beach has opened in early June.

But even now, water quality is the big issue of the season. In summer 2026, Rospotrebnadzor found microbiological levels above the limits at all the beaches on the city's side channel of the Lena and on Lake Sugun, both official and "wild." Swimming at the city beach was temporarily banned and only allowed again on July 24, after repeat tests. So check the latest data for the season before heading to the water.

When the Swimming Season Opens

The swimming season in Yakutsk depends heavily on the particular year, but the rough timeline is as follows.

The official opening is in early June. In 2026, the city beach opened on June 8, after positive results from water and sand tests and clearance from Rospotrebnadzor. The year before, it also opened in the first days of June.

The water is still cool at this point: the shallow lakes and the side channel warm up once daytime air temperatures of 25–30°C set in, by mid-June.

The peak is in July. This is the warmest month, when swimming is truly comfortable. The air is 26–35°C, the water in shallow lakes warms up to 20–24°C, and the days last almost twenty hours. These are the weeks when Yakutsk residents try to get to the water at every opportunity, unless, of course, swimming is restricted because of water quality.

The end comes in mid-August. From the second half of August, daytime temperatures drop to 18–22°C, the nights turn cold (7–9°C), and the water cools quickly. September brings night frosts, and by the middle of the month the temperature drops below freezing.

All told, the official swimming season lasts just over two months, from early June to mid- or late August. But truly warm water lasts five to seven weeks, mostly in July. In a cool summer, even less.

Mosquitoes and Smoke: The Downside

Summer in Yakutsk is generous not only with heat but also with biting insects. Mosquitoes appear at the start of summer, and towards August they're replaced by midges, against which repellent offers only partial protection. It's best not to go to the lake without insect repellent.

The second problem is wildfire smoke. Yakutia is one of Russia's most fire-prone regions, and in July and August the city is regularly shrouded in smoke. In bad years it hangs around for weeks, reducing visibility and air quality. You can swim on those days, but it's hardly a pleasure.

The Lena: Cold, but Mesmerising

Around Yakutsk, the Lena is a river about 5 km wide at flood level, with many islands and channels. Locals advise against swimming in the main channel: the water is cold and the current unpredictable. But as a landmark and a source of unforgettable experiences, it's irreplaceable.

Upstream, about 200 km from Yakutsk, begin the famous Lena Pillars: rock formations about 100 metres high (some individual cliffs rise more than 200 metres above the river, according to various estimates) that are a UNESCO World Heritage Site.

They're one of the main reasons tourists come to Yakutia in summer at all. A day trip usually combines a drive to the village of Tit-Ary with a motorboat ride from there, and takes 13–14 hours. There are also river cruises, which take about two days there and back.

What to Take to the Beach in Yakutsk

A beach-day kit in Yakutsk is different from a resort one:

  • Insect repellent comes first. Without it, mosquitoes and midges will turn your day out into an ordeal.

  • A windbreaker or light jacket: even in thirty-degree heat, the wind off the river can be cool, and the temperature drops sharply in the evening.

  • Sunscreen: UV at the 62nd parallel is deceptive. The sun isn't high, but the days are long, and it's entirely possible to burn after a few hours by the water.

  • Shoes for the shore: there aren't many sandy beaches with a gentle way into the water here. Lake shores are often boggy, with grass and silt.

A Few Weeks Worth the Wait

The swimming season in Yakutsk is a paradox: a city on permafrost where people seek shade from the sun. It's short, unpredictable and a little different every year. But that's exactly why Yakutsk residents treasure every warm day.

When, after seven months of frost, the air finally warms to thirty and the water in the side channel or a shallow lake turns warm, those few weeks feel more intense than a whole summer in the south.
