Makalu Region Weather: A Comprehensive Guide on What to Expect

The Makalu region is one of Nepal’s best trekking regions and Makalu Base Camp Trek is the major trek of this region. It is a high-altitude trek that takes trekkers from Num Village (about 1500 meters) to Makalu Base Camp (about 5100 meters). Hence, the weather in the Makalu region or during the Makalu Base Camp Trek can vary depending on elevation.

Overall Weather in Makalu Region

The Makalu region lies in the eastern part of Nepal. Here, the monsoon begins earlier (in June) and lasts longer (until late September) than in western Nepal. This is because eastern Nepal is closer to the Bay of Bengal. Lower-altitude areas are mostly warm and humid, while higher-altitude regions are mostly cold and dry. Even in the summer, higher regions will not be too hot. Weather conditions in the higher regions are unpredictable.

Spring Season (March-May)

Spring is the second-best season to embark on any high-altitude trek. It starts from early March till May in Nepal. The weather in the Makalu region is ideal for trekking because of the mild temperatures, clear views of mountains and skies, and stable weather. Also, this season brings forth a wide range of exotic flora and fauna for you to witness.
