Why Can't You Climb Everest in the Summer?

Published in Everest Climbing 2 mins read

Climbing Mount Everest in the summer is not advisable due to extremely hazardous conditions.

Summer on Everest: A Recipe for Disaster

Summer on Mount Everest presents a particularly dangerous environment for climbers, making ascents incredibly challenging and risky. The primary reasons for this include:

  • Heavy Rainfall: The monsoon season brings significant rainfall to the region, which can trigger avalanches and landslides, making the already challenging terrain even more precarious.
  • High Humidity: Elevated humidity levels during the summer create discomfort and can contribute to hypothermia, especially at higher altitudes where temperatures are already low.
  • Increased Avalanche and Landslide Risk: The combination of heavy rainfall and melting snow greatly increases the likelihood of avalanches and landslides, posing a significant threat to climbers.
  • Poor Visibility: Fog and cloud cover are common during the summer months, severely reducing visibility and making navigation difficult and dangerous.
  • Unstable Snow Conditions: Warmer temperatures at lower altitudes cause the snowpack to become unstable and more prone to collapsing, further increasing the risk of accidents.


Condition Impact on Climbing
Heavy Rainfall Triggers avalanches and landslides
High Humidity Contributes to hypothermia and discomfort
Poor Visibility Makes navigation extremely difficult
Unstable Snow Increases avalanche and collapse risk


Why These Conditions Make Climbing Impossible

These conditions make climbing extremely risky, and any attempt to do so would be dangerous. The combination of unstable snow, poor visibility, and the threat of avalanches makes navigating the mountain almost impossible and significantly reduces the likelihood of a safe and successful ascent.


Best Time to Climb Everest

The best time to climb Mount Everest is during the spring and autumn seasons, when the weather is more stable, visibility is better, and the risk of dangerous weather events is lower. These periods offer the most favorable climbing conditions, allowing for a more feasible and safer ascent.
