Summer in Yakutsk can really surprise you if you’ve always pictured Siberia as just a frozen wasteland. Winters here are absolutely brutal—some of the coldest on the planet—but the warmer months feel like a completely different world.
Average summer temperatures in Yakutsk usually land somewhere between mild and comfortably warm, often reaching the low to mid-20s °C (70s °F). Sometimes, heatwaves even push the mercury above 30 °C (86 °F).
You’ll notice incredibly long days packed with sunlight, since Yakutsk sits so far north. June and July in particular feel endless. The air dries out compared to winter, but you still get the occasional quick rain or a surprise thunderstorm.
These changes make summer here feel refreshing, even a bit unpredictable, especially after months of endless darkness and cold.
If you’re thinking about visiting Yakutsk in summer, get ready for comfortable weather, big blue skies, and just enough variety to keep things interesting. Honestly, summer is the best time to see the city and its wild surroundings.
Yakutsk Location and Climate Overview
Yakutsk sits deep in eastern Siberia and has some of the wildest temperature swings you’ll find anywhere. The city’s location, climate, and even the airport’s weather patterns all play into why you get both some of the world’s coldest winters and surprisingly warm summers.
Geographical Setting
Yakutsk sits on the west bank of the Lena River in Russia’s Sakha Republic. It’s about 450 kilometers south of the Arctic Circle, and honestly, it’s one of the biggest cities built right on top of continuous permafrost.
The city rests at roughly 100 meters above sea level. Because it’s so far from the ocean, there’s nothing to keep temperatures from swinging wildly between seasons.
The area around Yakutsk is mostly taiga forest and flat lowlands. Winter rules the landscape for most of the year, but when summer hits, everything thaws out fast. The city’s high latitude means daylight changes are dramatic—short, dim days in winter and really long, bright evenings in summer.
Climate Classification
Yakutsk falls into the subarctic climate (Dfc) category in the Köppen system. That means brutal winters, no real dry season, and cool to mild summers.
The average annual temperature sits around -8 °C (17 °F), which makes Yakutsk one of the coldest big cities anywhere. In winter, it’s not weird for lows to drop below -40 °C (-40 °F), but in summer, highs can shoot up to 25–30 °C (77–86 °F).
Precipitation stays light, with about 280–300 mm per year, and most of it falls during summer. Snow covers the ground for over half the year. The huge difference between winter and summer temps—sometimes more than 100 °C—is what really defines Yakutsk’s climate.
Yakutsk Airport Weather Conditions
Yakutsk Airport (YKS) sits just a few kilometers from the city, and it faces the same wild weather. The airport stays open all year, even with permafrost and heavy snow making things tough.
Airport winters bring low visibility, icy runways, and lots of fog from temperature inversions. Crews spend extra time de-icing planes.
In summer, the airport gets much nicer weather, with highs between 22–26 °C (72–79 °F). Rain showers pop up pretty often, but they don’t usually last. Winds are mostly light or moderate, but the odd storm can mess with schedules.
Since this airport is the main way in and out of Yakutsk, knowing what to expect from the weather helps you plan flights and ground travel.
Typical Summer Weather in Yakutsk
Yakutsk’s summer is the most comfortable season by far. Days feel mild to warm, nights cool down, and you get way more daylight than in any other season. Rainfall is moderate, and humidity shifts enough to change how hot or cool it feels.
Average Summer Temperatures
From June to August, Yakutsk enjoys its warmest weather. Highs usually hit somewhere between 21°C (70°F) and 26°C (79°F), with July topping the charts. These numbers might sound tame, but after the winter, they’re a relief.
June kicks things off with average highs around 21°C (70°F). July peaks at 25–26°C (77–79°F), then August cools off a bit, closer to 22°C (72°F).
Rainfall stays light to moderate, with 20 mm to 48 mm depending on the month. You won’t see any snow, so getting around is much easier.

Day and Night Temperature Ranges
Yakutsk days feel warm, but nights cool down fast. Expect daytime highs in the low to mid-20s Celsius (70s °F), while nights drop to 10–13°C (50–56°F).
You’ll want a light jacket or sweater in the evening, even after a sunny day. Nights almost never stay hot, so you can sleep comfortably, even without AC.
The long daylight—nearly 20 hours in June—also changes how the heat feels. The sun warms everything up all day, but after sunset, things cool off rapidly.
Humidity and Comfort Levels
Humidity in Yakutsk shifts by month, but summer generally feels comfortable. Relative humidity usually runs from 50% in June to about 70% in August. The air doesn’t feel bone-dry or sticky.
July and August can feel a little heavier, thanks to more rain and higher humidity. Still, temperatures stay mild, so it rarely gets muggy.
The mix of warmth, moderate humidity, and long days makes summer perfect for being outside. Walking, sightseeing, and exploring are so much easier when you’re not fighting biting cold or dry air.
Monthly Breakdown: June, July, and August
Summer in Yakutsk is short but pretty dramatic. Temperatures climb fast after the long winter, and things go from mild in early June to warmer and wetter by August.
June Weather Patterns
June marks the real start of warmth after endless months of cold. Daytime highs usually reach 15°C to 22°C (59°F to 72°F), while nights can still feel chilly, dropping to 7°C to 10°C (45°F to 50°F).
You’ll see daylight stretch past 18 hours at the beginning of the month. That means more time for outdoor plans, though evenings might catch you off guard with a chill.
Rain picks up compared to spring. On average, 30–40 mm of rain falls over several days. Showers don’t last long, but sometimes they’re heavy. Bringing a light rain jacket just makes sense.
Winds stay moderate, and humidity remains on the low side. June is a transition month, so packing layers helps you handle both warm afternoons and cool nights.
July Weather Patterns
July is Yakutsk’s warmest month. Daytime highs often hit 24°C to 26°C (75°F to 79°F), and nights are milder at 12°C to 14°C (54°F to 57°F). It’s the best time to stroll around the city or check out the rivers.
Rain becomes more frequent, with 40–45 mm falling on average. Showers come and go, but you’ll still get plenty of clear, sunny stretches.
Humidity ticks up a bit, but it’s not uncomfortable. Winds are usually light, so it can feel warmer than the thermometer says.
Daylight stays long, though you’ll notice it shrinking a little by the end of July. If you visit now, expect both sunny days and a few wet patches.
August Weather Patterns
August stays warm, but the weather gets a bit moodier. Daytime highs range from 20°C to 24°C (68°F to 75°F), and nights cool down to 10°C to 12°C (50°F to 54°F). You’ll feel the difference compared to July.
Rain peaks now, with 45–50 mm on average. Showers can be heavier, and a thunderstorm or two isn’t out of the question. Be ready for sudden weather changes, especially late in the month.
Humidity climbs, and you’ll see more cloud cover. There are still sunny days, but gray skies become more common.
By August’s end, you can feel autumn creeping in. Packing waterproof gear and an extra layer means you’ll stay comfortable as you catch the last of Yakutsk’s summer.
Precipitation and Rainfall Trends
Yakutsk’s climate is dry compared to a lot of cities, and most of the rain comes in summer. You’ll notice the seasons shift clearly, with wetter weather in late summer and barely any precipitation in the depths of winter.
Rainy Days and Dry Spells
Summer brings more rainy days than any other season in Yakutsk. The city isn’t especially wet, but you’ll get more frequent showers and the occasional thunderstorm.
August usually has the most wet days, with about 11 days of measurable rain. Most of these are short showers, not all-day downpours. February also sees around 11 days with precipitation, but it’s mostly light snow that barely adds up.
The difference is in the punch. Summer rains bring more actual water, while winter snow, even if it falls often, doesn’t add much to the totals. So, plan for the odd damp day in August, but expect lots of dry, sunny spells earlier in summer.
Monthly Precipitation Totals
Yakutsk averages about 280–300 mm (11–12 inches) of precipitation a year, which is pretty low for a city its size. Nearly half of that falls between June and September, so summer is definitely the wettest stretch.
August gets the most rain, with around 45–50 mm. July is a close second at 35–40 mm. June and September see a bit less, but still outpace the winter months.
February is the driest month, with just 7–8 mm on average. The huge seasonal swing in precipitation really shows how Yakutsk’s climate is shaped by endless cold winters and short, wetter summers.
Here’s a quick look at typical summer rainfall:
| Month | Average Rain/Snow (mm) |
|---|---|
| June | 25–30 mm |
| July | 35–40 mm |
| August | 45–50 mm |
| September | 25–30 mm |
Sunshine, Daylight, and Cloud Cover
Yakutsk’s summer means long days, plenty of cloud cover, and a mix of sunshine and gray skies. You get tons of daylight for outdoor plans, but clouds can cut down on how much direct sun you actually see.
Average Hours of Sunlight
During summer, Yakutsk soaks up some of its highest sunlight totals all year. June brings about 14 hours of sunshine per day, which is the most you’ll get. July and August offer a bit less, with 10–12 hours daily.
Still, sunshine isn’t a guarantee. Clouds and rain can eat into your time under blue skies. But compared to the dark, cramped winter days, summer feels like a whole new world.
The long sunlight hours create great opportunities for sightseeing, hiking, and river trips. Make the most of those long afternoons, since evenings stay light much later than you’d expect if you’re used to lower latitudes.
Cloudiness and Clear Skies
Yakutsk summers rarely feature endless clear skies. Most days, you’ll find overcast or mostly cloudy weather about half the time, especially in July and August when rainfall hits its peak. June might offer a bit more sun, but it’s still not what you’d call fully sunny.
You’ll often notice changing conditions throughout the day. Maybe the morning starts out bright, but by afternoon, clouds and showers might roll in.
If you want to spend lots of time outside, be ready for the weather to shift. Honestly, carrying light rain gear just makes sense, since showers can pop up even when the day seems pleasant.
Day Length Variations
The daylight in Yakutsk during summer feels pretty remarkable. In June, the sun stays up for almost 20 hours, and night brings only a short twilight. The city’s high latitude in Eastern Siberia causes this effect.
By July, the daylight drops a little, but you still get 17–18 hours on average. In August, days get noticeably shorter, down to around 15–16 hours of light.
You’ll enjoy those long evenings in early summer. As August approaches, it starts to feel a bit more like autumn with the shorter days.
Travel Tips for Experiencing Yakutsk in Summer
Yakutsk summers bring mild temperatures, tons of daylight, and the occasional rain shower. If you plan for these conditions, you’ll stay comfortable and actually enjoy your trip more.
Best Time to Visit
Late June through August usually feels the nicest. During these months, daytime highs typically hit 15°C to 26°C (59°F to 79°F). Nights cool off but rarely get chilly, often staying above 10°C.
In midsummer, daylight can stretch to almost 19 hours, so you get loads of time for sightseeing or just wandering around. Exploring the Lena River or checking out local museums and festivals feels much less rushed with so much daylight.
Rainfall stays moderate. July and August see more showers, with about 38–48 mm per month. The rains don’t last long but can get heavy, so expect a back-and-forth between sunny breaks and cloudy skies.
If you don’t mind cooler weather and want fewer people around, late May or early September might suit you. Just know the temperatures drop and weather gets a bit unpredictable, so pack a little extra just in case.
What to Pack for Summer
Pack clothing that can handle quick temperature changes. I always bring light layers—T-shirts, a long-sleeve shirt, and a light jacket.
Even in July, the evenings might surprise you with a chill, especially if you end up near the river.
Don’t forget rain gear. I recommend a waterproof jacket and a compact umbrella, since sudden showers happen more often than you’d think.
Pick shoes that are comfortable and water-resistant. Streets get muddy fast after it rains, and nobody wants wet socks.
With all that daylight, you might want to toss in an eye mask to help you sleep. Sunscreen and insect repellent come in handy too, especially when mosquitoes show up in wetter spots.
For day trips, I usually carry a small backpack with water, snacks, and a hat for sun protection. It just makes long hours outside way more comfortable.
