You’ve seen the photos of people with frozen eyelashes. Usually, those shots are from Yakutsk in January, when the air is basically a wall of ice and the mercury hits $-50$°C. But if you think this place is a year-round freezer, honestly, you’re in for a shock.
Yakutsk weather in summer is a wild, sweating contradiction. It doesn't just "thaw" out. It cooks. We’re talking about a city built on hundreds of meters of permafrost that suddenly finds itself under a sun that refuses to set.
The 60-Degree Swing You Didn't See Coming
The thermal range here is actually insane. Yakutsk holds the crown for the most extreme continental climate on Earth. While winter is a legendary nightmare, summer can easily see temperatures rocket to 30°C (86°F). In June 2020, the nearby town of Verkhoyansk hit a terrifying 38°C (100.4°F).
Think about that.
That’s a 100-degree difference from winter to summer. The ground stays frozen solid just a few feet down, but on the surface, you’re dealing with Mediterranean heat. It feels weird. You’re walking on a frozen crust while the air feels like a hairdryer.
July is usually the peak. The daily highs average around 25°C (77°F), but "average" is a bit of a lie. One day it’s a breezy 18°C, and the next, you’re hiding from a 32°C heatwave.
Why is it so hot?
Basically, it’s all about the geography. Yakutsk is tucked away in a basin far from any ocean that could regulate the temperature. Since there’s no sea breeze to cool things down, the sun just beats down on the Siberian taiga for 20 hours a day. The nights are short and barely provide any relief. The air stays heavy.
The Reality of the "White Nights"
Because Yakutsk is so far north, the sun barely dips below the horizon in June and July. It’s "kinda" beautiful but also totally wrecks your sleep schedule. Locals call this the time of the White Nights.
You’ll see people strolling the embankment of the Lena River at 2 AM. It feels like a permanent afternoon.
If you're visiting, an eye mask isn't just a luxury; it’s a survival tool. Without it, your brain never gets the "it’s time to sleep" signal. The light has this eerie, golden quality that makes the Soviet-era apartment blocks look almost poetic.
The Mosquitoes: Siberia’s Secret Air Force
If the heat doesn’t get you, the bugs will. This is the part people forget to mention in the travel brochures. When the permafrost melts slightly on the surface, it creates thousands of tiny puddles and bogs.

It’s a giant nursery for mosquitoes.
These aren't your typical backyard mosquitoes. They are aggressive, numerous, and seemingly immune to standard sprays. If you go hiking in the taiga without a head net or heavy-duty DEET, you will be eaten alive. Honestly, it’s the one thing that makes the $-40$°C winter seem almost preferable.
Wildfires and the "Smog" Season
Lately, Yakutsk weather in summer has been defined by a new, grimmer trend: smoke.
The Sakha Republic is mostly forest. When the heatwaves hit, the taiga catches fire. Because the region is so vast and remote, these fires can burn for weeks. In 2021, the air quality in Yakutsk was dozens of times worse than the WHO safety limits.
The sky turns a sickly orange. The sun looks like a dim red coin.
It’s a visceral reminder of how fast the Arctic is warming. For travelers, this means you need to check the fire maps before planning a trip in August. A "sunny" day can quickly turn into a lung-clogging haze that cancels flights and keeps everyone indoors.

What to Actually Pack (It's Not a Parka)
Packing for Yakutsk in July is a bit of a logic puzzle. You need to prepare for three different worlds:
- The Heat: Lightweight linen or cotton. You’ll want breathable fabrics because the humidity can feel higher than it actually is when the sun is beating down.
- The Protection: Long sleeves and pants are mandatory for the mosquitoes, even if it’s 30°C. Look for "insect-shield" clothing if you can find it.
- The Underground: If you visit the "Kingdom of Permafrost" (a museum inside a literal frozen hill), it’s $-10$°C inside. They usually provide coats, but you’ll want socks.
How to Survive the Heat
Since the city is built for extreme cold, most older buildings don't have great ventilation for the heat. Air conditioning is becoming more common, but don't count on it in every guesthouse or cafe.
Actionable Steps for the Heat:
- Hydrate constantly: The dry air and constant sun will dehydrate you faster than you realize.
- Hit the river: The Lena River is the heart of the city. Taking a boat trip to the Lena Pillars is the best way to catch a breeze.
- Go underground: Spend your afternoons in the Permafrost Institute or the Kingdom of Permafrost. It’s the world's most natural air conditioning.
- Eat local: Cold soups and kuyyrchak (whisked cream with berries) are summer staples for a reason.
Yakutsk in the summer is a fever dream of endless light, surprising heat, and a landscape that is literally shifting under your feet. It’s not for everyone, but for those who want to see the Arctic's "other" extreme, there’s nothing else like it.
Final Pro-Tip
Check the "Sakha Weather" Telegram channels or local apps for real-time wildfire updates if you're traveling in late July or August. The weather can change from "perfect summer" to "smoke emergency" in a matter of 24 hours depending on the wind direction.
Plan your outdoor activities for early June or early September to avoid the worst of the bug season while still enjoying the warmth.
