You've probably felt cold before. Maybe a biting January wind in Chicago or a damp morning in the Highlands. But there is a level of cold that exists on this planet that isn't just "uncomfortable"—it’s physically impossible for the human body to process. We are talking about places where your breath doesn't just fog; it essentially shatters.
So, what is the coldest recorded temperature on earth? Honestly, the answer depends on who you ask and how they were measuring it.
If you look at the "official" record books, the number you’ll see most often is -89.2°C (-128.6°F). This was recorded at the Soviet Vostok Station in Antarctica on July 21, 1983. For decades, this has been the gold standard. It was measured by a physical thermometer on the ground, which is what the World Meteorological Organization (WMO) requires for a record to be "official."
But wait. Science didn't just stop in the 80s.
With the advent of advanced satellites, we’ve found pockets of air that make Vostok look like a tropical getaway. In 2010, NASA satellite data identified temperatures as low as -93.2°C (-135.8°F) along a ridge in the East Antarctic Plateau. Since then, some researchers using refined thermal mapping have claimed to see dips reaching -98°C (-144.4°F).
The Vostok Record: Why 1983 Still Holds the Crown
To understand why a record from over 40 years ago hasn't been officially "beaten" by the much colder satellite numbers, you have to look at how meteorologists think. They are sticklers for protocol.
Vostok Station is located about 1,300 kilometers from the South Pole. It sits on about 3,700 meters of ice. On that fateful July day in 1983, a specific set of conditions aligned. The air was perfectly still. The sky was clear. A vortex of cold air trapped the heat from escaping, and the mercury just plummeted.

The WMO only recognizes ground-level air temperatures. This is because satellites measure "skin temperature"—the temperature of the actual snow surface—rather than the air a few feet above it. Usually, the air is a couple of degrees warmer than the ground. Because we don't have a guy standing on the East Antarctic Plateau with a thermometer at the exact moment the satellite pings a record, the Vostok record remains the official champion.
Life at -89.2°C
What does that actually feel like?
Basically, it’s a death sentence without specialized gear.
- Your lungs: If you took a deep breath of air at -80°C or -90°C, the cold would cause the moisture in your respiratory tract to freeze. It can literally cause your lungs to hemorrhage.
- Your skin: Exposed flesh freezes in seconds. Not minutes. Seconds.
- The sound: At these temperatures, the air is so dense and dry that sound travels differently. The ice under your boots doesn't "crunch"; it shrieks.
The New Contenders: Satellite Records and the East Antarctic Plateau
If we step away from the "official" WMO rules for a second, the real coldest place is clearly the East Antarctic Plateau.
A study led by Ted Scambos at the National Snow and Ice Data Center (NSIDC) used data from the MODIS sensor on NASA's Terra and Aqua satellites. They found that the coldest temperatures occur in small "hollows" or depressions in the ice.
Imagine the ice sheet isn't perfectly flat. It has tiny dips, maybe only a few meters deep. Cold air is denser than warm air, so it sinks into these hollows. If the sky stays clear for several days, the heat radiates out into space, and that trapped air gets colder and colder until it hits a physical limit.

"It's a place where Earth is so close to its limit, it’s almost like another planet," Scambos noted during his research.
The record they found—that -98°C (-144.4°F) figure—is truly staggering. To put that in perspective, CO2 (dry ice) freezes at -78.5°C. In these parts of Antarctica, the very air you breathe is approaching the point where the gases in it want to change state.
Why Siberia is Actually More Impressive
Antarctica is a desert of ice. Of course it’s cold. But there’s a place where people actually live that gives the South Pole a run for its money.
Oymyakon, Russia, is widely considered the coldest permanently inhabited settlement on Earth. In 1933, it hit -67.7°C (-89.9°F).
Think about that for a second.
In Antarctica, you have scientists in high-tech gear staying in pressurized, heated stations. In Oymyakon, kids go to school until the temperature hits -52°C. People have to keep their car engines running 24/7 because if they stop, the oil freezes solid and the vehicle becomes a 2-ton paperweight.
Is it getting harder to break the record?
You'd think with climate change, we’d never see these records again. Kinda true, but also complicated.
While the globe is warming, the weather in Antarctica is driven by the Southern Polar Vortex. When that vortex is strong, it keeps the cold air locked over the continent. Ironically, some models suggest that as the rest of the world warms, the temperature extremes in the heart of Antarctica might still hit those "deep freezes" because the air there is becoming even drier. And dry air loses heat much faster than moist air.
However, the "official" Vostok record is safe for now. Most of the warming is happening at the coasts of Antarctica, where the ice is melting into the sea. The high plateau is like a fortress of cold that is holding out as long as it can.

Actionable Insights for Extreme Cold Knowledge
If you’re fascinated by these extremes or planning a trip to somewhere significantly less cold (like the Arctic or a ski resort), here is what the "Vostok Level" of cold teaches us about survival:
- Layering isn't just a suggestion: The scientists at these stations use a "Vapor Barrier" layer. Moisture (sweat) is your enemy. If you sweat and that moisture stays against your skin, you’ll be hypothermic in minutes once you stop moving.
- Protect your intake: In extreme cold (even just -20°C), breathing through a buff or scarf is vital to pre-warm the air before it hits your bronchial tubes.
- Understand the "Skin vs. Air" gap: Always check the wind chill, not just the base temp. Just as the satellite measures surface temp and the thermometer measures air, your body feels the "sensible" temperature, which is often 10-15 degrees colder than the forecast.
If you want to track this in real-time, the British Antarctic Survey and the Australian Antarctic Division maintain live weather feeds from various stations. Watching the sun go down for six months at Vostok via a data feed is a humbling reminder of just how extreme our planet can get.
Check the current live data from the Amundsen–Scott South Pole Station to see how close they are to the record today. It's usually a "balmy" -50°C this time of year.
