How do the Winds Affect Climbers on Mount Everest?


The experience of Mount Everest is as thrilling as it is challenging. However, for anyone seeking to conquer this majestic summit, the weather is many times their biggest concern – and rightly so. A significant part of Mount Everest’s weather is the wind. Wind in mountainous areas can be very unpredictable and often turns the dream of reaching the summit into a deadly ordeal. In this article, we will delve into how the winds affect climbers on Mount Everest.

The Unpredictable Winds of Mount Everest

Wind speeds on Mount Everest can reach above 200 mph, making it one of the windiest places on earth. Many climbers have reported that these extremely high winds can blow people off their feet, smash ice and rocks around, and make it incredibly challenging to move forward.

Mount Everest’s winds are primarily due to the jet stream – a narrow band of high speed winds in the upper levels of the atmosphere. When the jet stream hits Mount Everest, the winds intensify, making climbing conditions very dangerous.

The Adverse Effects of Wind on Climbers

High winds can cause several problems for climbers. The most obvious is the physical difficulty it imposes. In excessive wind conditions, climbers struggle to remain upright, their movements are hampered, and progress is painfully slow.

Furthermore, high winds can lower the actual temperature, leading to frostbite and hypothermia. The wind chill can make the environment feel drastically colder than the actual temperature, quickly robbing the body of its vital heat.

Beyond physiological challenges, wind can also cause psychological stress. The consistent roar of the wind can lead to a sense of isolation, making the climb seem even more daunting.

How Climbers Deal with the Wind

Given the severe risks associated with high winds on Mount Everest, climbers need to be well-prepared. During their climb, they must continuously monitor the weather, enabling them to seek shelter before the winds gain full strength.

Clothing plays a crucial role, too. To combat wind chills, climbers wear specially designed, wind-proof clothing that is layered to trap heat and shield against the elements. Moreover, climbers often use ropes to secure themselves, reducing the risk of being blown off the mountain by a sudden gust.


While the gushing winds on Mount Everest pose a significant challenge and risk, equipped with the right knowledge, gear, and respect for these natural forces, climbers can enhance their chances of a successful, safe ascent. The unpredictability and intensity of these winds add to the allure of the Mount Everest climbing expedition, making the journey as formidable as the peak itself.


1. What is the maximum wind speed recorded on Mount Everest?

The highest wind speed ever recorded on Mount Everest was 175 mph (282km/h) in February 2004, but winds are estimated to have reached over 200 mph on many occasions.

2. How does wind affect the climbing speed on Mount Everest?

Strong winds can drastically slow climbers down. In addition to physically hindering their movement, they make the environment colder, which can further affect climbers’ stamina and progress.

3. What clothing is recommended for climbers to protect themselves from the wind?

Windproof, layered clothing is vital for climbers. The outer layer should be a hard-shell jacket and pants that are both windproof and waterproof. Beneath this, there should be an insulating middle layer and a moisture-wicking base layer.

4. How do climbers predict wind conditions on Mount Everest?

Climbers rely on meteorological data and forecasts, often provided by specialized weather companies. They need to understand not just current conditions but also how conditions might change during the critical window of their ascent.

5. Why can’t climbers just wait out windy days at camp?

Waiting out windy weather isn’t always possible due to limited supplies of food and oxygen. Also, a prolonged stay at high altitudes can lead to altitude sickness and other health issues.

6. Is there a time of year with less wind on Mount Everest?

There are two major climbing seasons – spring (April-May) and fall (September-November). Spring is the most popular season because the jet stream typically shifts north in May, leading to lower wind speeds and more stable weather scenarios.
