Climate during Mera Peak Climbing

The climate of the Mera Peak climb varies dramatically, from the humid subtropical climate of the lower elevations to the continuous snow of the higher altitudes. The Himalayan region begins as the ridges rise above 3,500 meters and continue into the subalpine and alpine zones of Mera Peak. These areas are typically snow-covered and are the coldest parts of Nepal all year. The Mera Peak region has a significant impact on the climate of the entire country as well as the Indian subcontinent.

During the winter, the vast Himalayan range blocks cold air from Inner Asia from entering Nepal, resulting in a relatively dry winter in Mera Peak. The subalpine zone can have up to 230 days of frost, but the alpine zone has frost cover for most of the year. As you ascend Mera Peak, you will pass through various climates.
