What is the Monsoon Season in Nepal?
The monsoon in Nepal typically runs from mid-June to early September, with July and August being the wettest months. During this time, warm, moisture-laden winds from the Bay of Bengal sweep across the Indian subcontinent and rise into the Himalayas, causing heavy rainfall, especially in lower and mid-altitude areas.
Although the higher Khumbu region is partly in the rain shadow areas of the Himalayas, it still receives occasional rain, cloudy skies, and increased humidity—especially in the lower sections of the trail.
