Despite the season, altitude highly influences a region’s weather and climatic conditions. The weather also becomes unpredictable as you ascend to higher altitudes. During the Everest Three High Pass Trek, you will travel from low-altitude areas to high altitudes above 5000 meters. So, you will experience varying temperatures. Here is a brief of the different seasons and weather conditions.
Spring (March to May)
Spring is one of the best times to trek in Nepal. This season offers pleasant weather with moderate temperatures for the Everest Three High Pass Trek. The precipitation level is low, so there is minimal chance of rainfall, but there can be occasional rain showers. The flora and fauna are the most active at this time of the year. Trekkers can enjoy the trails of colorful, blooming forests of rhododendrons and Himalayan wildflowers.
The sky is clear, and the visibility is brilliant. Thus, one can enjoy the gleaming snow-capped mountain panoramas. The temperature at lower altitudes ranges between 10 to 20 degrees Celsius. However, the temperature in higher areas remains cold and ranges between -5 to 10 degrees Celsius.
Summer (June to August)
As spring transitions into summer, there is a rise in temperature across the country. Likewise, the monsoon season also enters Nepal. Lower areas receive heavy rain, making the trails wet, muddy, and slippery. Rain clouds cover most of the views, as visibility is relatively poor. The heavy rain also increases the risk of landslides and mudslides.
Because of the hazards, summer is not ideal for trekking Everest Three High Pass. It makes trekking more challenging. The temperatures in the lower areas range between 15 and 25 degrees Celsius, while the temperatures at higher altitudes can reach 5 to 15 degrees Celsius.
Autumn (September to November)
Autumn is another best time for the Everest Three High Pass Trek and is also a peak season for trekking in Nepal. The season is a favorite among trekkers due to the stable weather and mild temperature. Visibility is also excellent, as the rain from the prior season cleanses the surroundings. Similarly, the autumn foliage adds colors to the vibrant landscapes.
The autumn season offers one of the most spectacular mountain views. However, it starts to get chilly as the season progresses. The daytime temperature of lower altitude regions is between 10 to 20 degrees Celsius. The temperature of higher altitudes can range from 10 to -5 degrees Celsius.
Winter (December to February)
As the winter season begins, the temperature starts to drop. The temperature of higher elevations plunges to freezing. Heavy snowfall can also cause the risk of avalanches and blockage of high mountain passes. Similarly, the trails get icy and slippery. It is incredibly challenging to trek in such harsh weather conditions. However, many seasoned trekkers prefer winter for an adventurous trek experience.
Trekking in winter requires a lot of meticulous planning and preparation. Trekkers will also need specialized equipment. The daytime temperature of lower altitude regions ranges from 5 to 10 degrees Celsius. Meanwhile, the nighttime temperature can get from -10 to -5 degrees Celsius or even lower.
