The climate of the park is dominated by the southwest summer monsoon. Temperatures vary greatly due to the extreme difference in altitude in the entire area. Most of the annual precipitation occurs from June to September. In fall (October – November) and spring (April – May), days are warm and sunny, and nights cool. In spring, rain at 3000 m elevation often turns to snow at higher elevations. In winter from December to March, days are clear and mild but nights near freezing
