If you’re sitting on your couch wondering what is the temp in antarctica today, you probably imagine a frozen wasteland where eyelashes freeze instantly. Honestly? You’re mostly right. But today, Saturday, January 17, 2026, is actually the height of the "Great Antarctic Summer," and the numbers might surprise you.
Antarctica is basically a giant ice cake, and the temperature depends entirely on where you’re standing on that cake. If you're at the beach, you might be in a t-shirt (well, a very thick one). If you’re at the South Pole, you’re in a world of hurt.
The Coastal "Heatwave": McMurdo and the Peninsula
Right now, near the edges of the continent, things are looking almost civilized. At McMurdo Station, the main U.S. research hub, the mercury is hovering around 21°F (-6°C). It’s overcast there today, and honestly, that’s warmer than a January afternoon in Chicago or Minneapolis.
Up on the Antarctic Peninsula—that long finger of land pointing toward South America—it’s even balmier. At Esperanza Base, they’re seeing highs of 35°F (2°C). It's actually melting. You've got light snow and some wind, but at 2°C, the penguins are probably thinking about a spa day.
This is why most tourists only go to the Peninsula. You get the icebergs and the whales without the "my-nose-is-falling-off" cold.

The Deep Freeze: Life at the South Pole Today
Once you move inland and head "up" to the high plateau, the story changes fast. The Amundsen-Scott South Pole Station is currently sitting at a steady -27°F (-33°C).
Wait.
Is that actually warm?
For the South Pole, yeah, kinda. Since it’s mid-January, the sun hasn’t set in months. It’s just circling the sky, beating down on the ice. While -27°F sounds like a nightmare, remember that in six months, this exact spot will plummet to -80°F or worse. Today is basically a tropical vacation for the scientists living there.

Current Readings Across the Ice (January 17, 2026)
- Vostok Station: This is usually the coldest place on Earth. Today it’s chilling at -30°C (-22°F). It’s overcast with some light fog, making it feel way more ominous than the temperature suggests.
- Williams Field: Near the Ross Ice Shelf, it’s a crisp 18°F (-8°C).
- The South Pole: -27°F with a light breeze. The wind chill makes it feel closer to -40°, which is the magical point where the Fahrenheit and Celsius scales meet in a frozen hug.
Why Does the Temperature Vary So Much?
Antarctica isn't just a flat sheet of ice. It's a massive mountain range buried in snow. The interior is a high plateau, thousands of feet above sea level.
- Elevation: The South Pole is about 9,300 feet high. That’s like standing on a mountain in the Rockies, but with no trees and a lot more penguins (just kidding, no penguins live at the Pole).
- Distance from the Sea: The ocean acts like a giant space heater. It keeps the coastal bases like McMurdo and Esperanza from dropping into the abyss.
- The Albedo Effect: The ice reflects about 80% of the sun's energy back into space. Even when the sun shines 24/7, the ground just refuses to soak up the heat.
What Most People Get Wrong About Antarctic Weather
People think it’s always snowing there. Actually, Antarctica is the world's largest desert.
It’s too cold for much snow to fall in the interior. What you see blowing around at the South Pole today isn't new snow; it's just old snow from the 1970s being pushed around by the wind. The air is so dry that your skin will crack in hours if you don't slather on the lotion.
Also, "Summer" doesn't mean "Warm." It just means "Less Deadly." If you stepped outside at the South Pole today in your pajamas, you’d still have a very bad time within about three minutes.

How to Track the Temp Yourself
If you’re obsessed with the data, you can actually watch it in real-time. Most major research stations have "webcams" and live weather feeds.
- Check the USAP (United States Antarctic Program) website for live feeds from McMurdo and the South Pole.
- Look at Meteo-France or the British Antarctic Survey for data on the Peninsula.
- Check the COMNAP (Council of Managers of National Antarctic Programs) lists if you want to see what the folks at the Chinese, Indian, or Italian stations are dealing with today.
Your Next Steps for Exploring the Cold
If you're planning a trip or just geeking out on the climate, don't just look at the raw temperature. Look at the wind speed. A 20°F day on the coast is lovely until a 50mph katabatic wind starts blowing off the plateau. That'll drop the "feels like" temp to dangerous levels in seconds.
If you want to stay updated on how the ice is changing this season, keep an eye on the National Snow and Ice Data Center (NSIDC) reports. They track the sea ice extent, which is currently near its summer minimum.
Keep your parka handy—even if it's just for the walk to your fridge.
