how cold is mount everest

The coldest regions on the planet include Mount Everest, and the area is no different in extreme weather conditions. The mountain rises to 29,032 feet and gets even colder with altitude. Even during warmer seasons, the temperature of the Mount Everest Region is far below 0 degrees Celsius. Moreover, due to the elevation, the rarefied atmosphere adds to the wind chill factor. Mount Everest’s geographical situation also helps in this regard. 

Mount Everest is located on the border of two weather systems, which cause rapid wind direction changes, speed changes, storms, and temperature fluctuations. Due to its unpredictable weather, climbers can never be sure about the conditions they will face. So, how cold is Mount Everest? Temperatures at the summit can drop to as low as -60°C (-76°F) in winter, while even in the warmer months, it rarely rises above freezing.

The Basics of Mount Everest’s Location and Elevation

Everest Base Camp Elevation
  • Mount Everest is situated at the intersection of Nepal and Tibet and is part of the Himalayan range.
  • The summit of the mountain rises as high as 29,032 feet above sea level, which adds to its bitterly cold climate.
  • As you scale the height, the air becomes less dense, and the temperatures get colder, with a steep drop in temperature.
  • The temperature here may still prove frigid even at the basal camp or 17600 feet above sea level.
  • Mount Everest’s altitude brings it into contact with different weather systems, including the warm, moist air masses carried by the monsoons and the cold, dry air at altitude.
  • Altitude coupled with geographical position is why Mount Everest’s height temperature is one of Earth’s lowest and most erratic climate conditions.

Exploring the Weather Patterns on Everest

Mount Everest’s weather is known to be highly changeable. Such changes can occur so rapidly that a bright, clear sky can become threatening. The Mount Everest temperature in summer overlaps with the southwest monsoon season; however, even with this seasonal rainfall, the average summer temperature at elevations above sea level remains freezing. 

The monsoon’s rain and snow usually fall in the mountain’s lower reaches while the upper sections remain cool and dry. So, how cold is Mount Everest?

Temperatures may also plunge considerably, dropping to about -60 degrees F, inhospitably cold. Winds on the summit of Everest can be as strong as 200 miles an hour, further compounding the chill factor and inducing life-threatening situations. For those inclined to ask questions such as “How cold is Mount Everest in winter?” or “How cold is Mount Everest in March?” It is absolutely and positively cold. These months, especially for climbers, are the worst because of the extremely low temperatures and unpredictable weather patterns.

Factors Influencing Cold Weather on Everest

A thorough analysis of a few contributing factors to Mount Everest’s extreme climate is fundamental in appreciating the cold weather conditions.

Here’s a look at what causes the cold weather conditions in the famous mountain:

Altitude

How cold is Mount Everest? The mountain’s location at high altitude, combined with its proximity to both the Indian monsoon and the Tibetan high-pressure system, results in extreme cold. The elevation gained from the mountain itself is one of the primary contributors to cold weather. As altitude increases, the warmth enveloping us decreases. On the Everest climb, there is an average temperature decline of about 6.5°C (11.7°F) after climbing each vertical 1000m (3280ft) height. Therefore, it remains cold even at the base camp, already above 5000 m (17598 ft). It is too cold at the extremes, and one could quickly freeze out.

This significant temperature decline means it remains frigid even at the Everest Base Camp trek elevation, which is over 5000m (17,598 ft). The freezing conditions at such high altitudes can make it dangerous, and one could quickly freeze without proper preparation and gear.

Latitude

As the globe turns, Mount Everest stands at an elevated latitude and has a more relaxed environment relative to mountains nearer to the equator. Its location in the Himalayas exposes it to colder air and weather conditions, making it even colder.

Seasonal Changes

Various weather conditions are experienced at different times of the calendar year. Spring, which follows winter, is relatively warm, but temperatures can still drop below zero. Summer showers bring higher temperatures, but the rains tend to be more chilly. With changes in the calendar year, warmer climates, or rather chilly ones, are experienced with the onset of winter. And winter—for many engaged in climbing—is almost impossible due to very low temperatures.

Wind Patterns

Winds also contribute to how cold it feels. Stronger winds can even cause the temperature to feel lower than it is. On Everest, for example, winds can sweep at speeds over 160 km/h, resulting in serious dangers such as frostbite. 

Geography

The structure of Mount Everest’s topography can alter the weather. Its steep slopes can also act like wind tunnels, thus forming small weather systems that can abruptly reduce temperatures and bring in storms.

Sunlight Exposure

The amount of sun that shines on the mountain varies from season to season. Days are longer in spring and summer, but the high altitude also ensures low sun temperatures. Most of the time, extreme daytime temperatures are recorded, which happens at night and creates additional difficulties for climbers.

Climate Change

Is there any change in Climatic conditions on Everest and its surrounding areas? Indeed, though the mountain is bitterly cold, global warming and its consequences can sometimes make the weather unpredictable. Modification of ice and snow can also lead to impossible climbing routes.

With better insight into the above factors, climbers can strategize and cope with how cold is Mount Everest and its challenging conditions. Understanding the rapid wind direction changes, storms, and temperature fluctuations allows climbers to prepare accordingly. The extreme cold at the summit, which can plummet to -60°C (-76°F) in winter, requires specialized gear and planning to ensure safety and survival during the ascent.

How Altitude Affects Temperature on Everest

  • The height of Mount Everest also considerably contributes to the extreme cold experienced at this mountain.
  • This is referred to as the average lapse rate. As you ascend, the temperature falls sharply—by approximately 6.5 °C (11.7 °F) for every 1000 m climb.
  • Yet camp can feel warm; the top of the mountain is much worse, as temperatures can reach 40°F or even worse.
  • High altitudes have rare air, so the body has difficulty holding any warmth, making the cold more penetrating.
  • At the highest point of the mountain, climbers contend with very harsh temperatures and low oxygen levels, which make it impossible for anyone to survive.
  • The climate of Mount Everest becomes considerable to a climber because altitude elevates the conditions to be endured.

Comparing Temperatures Throughout the Year

There are sharp temperature changes on Mount Everest every month, each presenting hurdles for scaling Mount Everest. Studying the temperature, as well as the degree of cold in every season, will give a clearer perspective on this issue:

Spring (March to May):

Temperature: Come March, the temperature at the peak of Mount Everest could be anywhere between -20°F and thereabouts. By late April and the beginning of May, this temperature could be slightly less than -10°F.

Level of Coldness: Conditions improve as we progress into spring, but climbers acclimating to such altitudes still experience cold temperatures. Icy winds and frost accompany early spring, so climbers must be well-equipped for these weather conditions.

Sunlight Exposure: Days become longer during spring, offering more sunlight to climbers, although the nights tend to be very cold. 

Wind chill factor: Strong winds make the surrounding temperatures feel colder than they are, usually on top of the already low environmental temperatures.

Summer (June to August):

Temperature: The summit temperatures during the summer months range from approximately -10 to -20 °F. Although this may sound mild compared to winter, it is still quite dangerous for anyone who intends to climb.

Level of Coldness: Mount Everest’s summer temperatures are milder than other seasons, but strong winds and the possibility of storms still have chilling effects. The monsoons are also characterized by high humidity levels, which makes the cold even worse, hence the need for good equipment to help keep the body warm.

Drizzle:  This season also sees more rain distribution, mainly because of the monsoon, which can cause unpleasant wet and slippery surfaces on the lower levels.

Temperature Fluctuations: Climbers can expect altitude elevation and a daytime temperature increase; however, a dramatic drop in temperature at night may be experienced, hence the extremes that climbers ought to be ready for.

Autumn (September to November):

Temperature: Climactic conditions for a climber’s activity are still suitable in September, with November’s mountaintop temperatures dipping to as low as -20 °F or lower.

Level of Coldness: Climate change is often associated with the onset of winter. High-altitude climbers may still face strong winds and cold weather, making the internal environment very cold. This cold environment demands thorough and flexible preparatory work to cope with its challenges.

Daylight Hours: Autumn days tend to shorten, providing little climbing time in safe conditions, which can stress climbers and cause them to finish their ascents faster.

Frost Formation: The inevitable drop in temperature also increases the amount of frost that coats the equipment and gear. Hence, climbers must ensure their equipment does not succumb to frost.

Winter (December to February):

Temperature: Everest’s winters are bitterly cold; the temperatures at the peak tend to be around -60°F or worse.

Level of Coldness: Climbing Everest becomes very difficult during these months. The weather conditions are aggressive and dangerous to anyone who hopes to climb there. Very strong winds pose a risk to life, causing even the most skilled climbers to refrain from attempting climbs in winter.

Ice and snow accumulation: excessive precipitation, such as snow, can form thick sheets of ice along climbing routes, making climbing more dangerous.

Extreme Wind Chill: The wind chill factor can also contribute to even more drastic temperature drops, making it extremely difficult to exist without the right equipment.

Preparing for the Extreme Cold on Everest

On the way to Everest Base Camp trek from Jiri

Conquering the peak of Mount Everest is no mean feat; in this case, especially the cold, call for adequate preparation. Proper preparation is vital, whether aiming for the summit or embarking on the Everest Base Camp trek.

Here’s how trekkers and climbers can gear up for the challenging conditions they will encounter:

Clothing and Gear

It’s essential to wear a series of layers of clothing that provide warmth and wick away moisture. A good base layer helps keep the body warm and dry, while warm fleeces, down, or synthetic jackets aim to insulate the core. An outer layer, mostly a waterproof and windproof shell, protects the climber from strong winds and rains. It is essential to carry additional items prone to frostbite attacks, such as gloves, hats, and face masks.

Quality Sleeping Equipment:

Climbers need good-quality sleeping bags that can withstand very low temperatures. They should also buy insulated sleeping pads to avoid losing warmth to the cold surface on which they lie. Such items can help a great deal when it comes to comfort and warmth during breaks.

Hydration and Nutrition:

Hydration is essential even when the temperatures are low and snow is present. Fluids help the body maintain temperature and energise effectiveness. Nutrition-dense foods like energy bars and high-precision meals preserve energy levels for extended vertical ascents. Well-cooked food and hot drinks also help increase internal body levels.

Acclimatization:

Climbers must allow their bodies time to acclimate to the elevation and low temperatures. That is why it is necessary to climb slowly and avoid such altitudes. This minimises the risk of altitude sickness and allows the body to adapt to the high oxygen saturation rate. This includes installing the so-called lower base camp for a while and climbing a certain altitude, followed by a return to ground level.

Understanding Weather Patterns:

It is essential to monitor the weather and its changes, as how cold is Mount Everest plays a significant role in determining the safety and success of a climb. Weather is a major climatological factor for most climbers, so climbers should be cautious in all-weather patterns, especially during the turnaround seasons, as alterations are commonplace.

Mental Preparation:

There is also the mental aspect that one may find hard to imagine about climbing in the bitter cold. Climbers should brace themselves for the inevitable factors like solitude, fatigue, and the stress of extreme weather hovering over them. One way climbers can deal with stress is by learning and practising mental toughness. 

Preparing for the trek is not just about gear; understanding how to train for the Everest Base Camp trek is equally essential. Training should include building endurance and strength and familiarizing yourself with unpredictable weather conditions, which will be crucial for a successful and safe trek.

Emergency Planning:

Another essential component is developing a comprehensive emergency response. This means locating and using emergency equipment, having first aid injury treatment in possession, ensuring the availability of communication gadgets and knowing where to evacuate and where the nearest available shelter point can save lives during many extreme scenarios.

Apart from the climbing techniques required, the climbers should get accustomed to the extreme climatic conditions, especially the cold, which acts as another hurdle. To ensure that a climber can safely conquer the summit, he has to adjust himself to the specific features of the mountain as well as its shifting weather patterns.

When assessing the Everest Base Camp trek’s difficulty, it’s essential to consider both the physical demands and the harsh, unpredictable weather. To safely conquer the trek or summit, climbers must adapt to the mountain’s specific features and shifting weather patterns.

Faqs on How Cold is Mount Everest

The coldest temperature recorded on Mount Everest is approximately -60°C (-76°F). Such extreme temperatures are usually the climax of the winter season. Nevertheless, it can even be colder due to the effect of wind chill and high altitude.

The ascent of Everest in the summer season is almost impossible due to the monsoon weather. This season brings lots of rain and high humidity, which causes many avalanches. The weather becomes unpredictable, and the conditions are not conducive to the climb. Most climbers prefer the spring months because the weather is more favourable.

To be precise, it rains on Everest, especially during drought season. However, the higher the altitude, the more precipitation occurs as snow since the temperatures are lower. This snow can make it easier said than done for the climbers. However, rain is more frequent in the base camp than in the summit.

Nighttime on Everest and its associated mountains sees a tremendous drop in temperature, with averages spanning from -20°C down to -30°C (from -4°F to -22°F). This extreme temperature dip also disturbs climbers’ rest and recovery periods. Such low temperatures are possible frostbites. During this time, hunting is still essential for health and protection.

On Everest, climbers remain warm by putting on several layers of clothes made of good-quality insulating materials. They wear down coats, thermal underwear, windbreaker jackets, and many more. Insulated gloves, hats, and face masks are also crucial in averting the effects of the cold. Keeping active when climbing is helpful because it encourages heat production.
