How Cold Is Mount Everest? Everest Base Camp Weather Guide

- Magnificent Himalayan Treks

When people think about Mount Everest, the first thing that comes to mind is that it's the tallest mountain in the world. But there’s more to it than just height. The Mount Everest peak is also known for its extreme cold, hurricane-like winds, and unpredictable weather. If you're planning an Everest Base Camp Trek or thinking about summiting to the top of Mt Everest, understanding the Everest temperature and seasonal conditions is very important.

At Magnificent Himalayan Treks, we’ve guided thousands of people on the Everest Base Camp Trekking journey and also supported some on their climb to the summit. In this guide, we’ll explain how cold it gets on Everest, what the weather is like in each season, and how you can stay safe.

How Cold Is Mount Everest?

Mount Everest is always cold, no matter what time of year you visit. But the temperature depends on where you are on the mountain—whether you are at the Everest Base Camp or near the summit in the "Death Zone."

Temperature at the Top of Mount Everest (Summit Area)

The summit, or top of Mt Everest, is one of the coldest places on earth. During the daytime, the average temperature is around -36°C (-33°F). At night, it can drop to -60°C (-76°F). With wind chill, it can feel like -80°C (-112°F). These are deadly temperatures, and this is why only experienced climbers with oxygen support and the right gear try to reach the summit.

Another reason it's so cold is because of the high altitude. At 8,848 meters, the oxygen level is just 33% of what we have at sea level. That means your body loses heat faster, and the risk of frostbite is very high.

Temperature at Everest Base Camp

For those doing the Everest Base Camp Trek, the temperature is much more manageable, though still cold. Here’s what it usually feels like in different seasons:

Even in the warmest months like July, the average temperature at Everest Base Camp stays around -3°C.

Why Is Mount Everest So Cold?

1. High Altitude Means Less Heat

One major reason why Mount Everest temperature is so low is because of its altitude. As you go higher, the air becomes thinner and cannot hold heat. At the Mount Everest peak, the air pressure is just one-third of what we have at sea level. So heat escapes easily, and you feel much colder.

2. Jet Stream Winds

Another factor is the jet stream, which is a strong wind current that flows at high altitudes. On Mount Everest, these winds can blow at speeds over 200 km/h. They blow away any warmth from the body and make the cold feel even worse. These winds also make climbing more dangerous, especially near the summit.

3. Climate Change and Glacial Melting

Due to climate change, the weather on Everest is becoming harder to predict. Glaciers are melting, snowfall patterns are changing, and avalanche risks are increasing. This adds new dangers to both the Everest Base Camp trek and summit climbs.

Everest Weather by Season

Choosing the right season is important if you want to enjoy your trek and stay safe. Here’s a breakdown of what to expect in each season:

Best Time for Everest Base Camp Trekking

• Spring (April to May): This is one of the best times to trek. The days are warmer, skies are clear, and rhododendrons are in full bloom. Visibility is good for photos and mountain views.
• Autumn (September to October): Another great season for Everest Base Camp Trek. The weather is cool and dry, with fewer clouds and less rain. It's perfect for scenic photography and stable trekking conditions.

Seasons to Avoid

• Winter (December to February): The temperature at Everest during this time is extremely low. There’s a high risk of frostbite, especially at night. Only very experienced trekkers go during this season.
• Monsoon (June to August): This is the rainy season. Trails become muddy and slippery, and there's low visibility due to heavy clouds and snowfall at higher altitudes.

Best Time to Climb to the Top of Mt Everest

For summit climbers, the best window is mid-May, when the jet stream shifts for a short period. This allows a few days of less wind and better climbing conditions. Most successful climbs to the top of Mt Everest happen during this time.

How to Survive the Cold on Everest

If you’re planning to do the Everest Base Camp Trek or climb higher, you need the right gear and preparation to handle the cold.

1. Must-Have Gear for the Cold

• Down Suit or Jacket: Choose one that’s rated for -40°C or colder.
• Windproof Gloves and Socks: These help prevent frostbite.
• Oxygen Mask (for climbers): Essential for the summit area.
• Four-Season Sleeping Bag: Keeps you warm at night in teahouses or tents.

2. Acclimatize Properly

Spending extra days at key spots like Namche Bazaar (3,440m) helps your body adjust to the altitude. Also, hiking up to Kala Patthar (5,643m) gives your body a chance to handle cold and thin air.

3. Protect Yourself from Frostbite and Hypothermia

In very cold temperatures, frostbite can happen in just minutes if your skin is exposed. Fingers, toes, nose, and ears are at the most risk. Wear proper gloves and face protection. Also watch out for hypothermia, where your body temperature drops dangerously low. Always layer your clothing and stay dry.

FAQs About Everest Temperature and Weather

Q1. What is the coldest temperature ever recorded on Everest?

The lowest recorded temperature near the summit is -60°C (-76°F), and with wind chill, it can feel like -80°C (-112°F).

Q2. Is Mount Everest cold all year round?

Yes, it is always cold. Even in summer, the Everest Base Camp temperature is around -3°C, and the summit is below -20°C.

Q3. Why is Everest colder than other peaks?

Because it's the highest. There’s less oxygen, strong jet stream winds, and not much atmosphere to trap heat. That makes the temperature at Everest extremely low.

Final Thoughts: Conquering Everest’s Cold

Whether you're trekking to Everest Base Camp or aiming for the top of Mt Everest, one thing is guaranteed—it's going to be cold. But with the right planning, gear, and support, you can enjoy the journey while staying safe.
