Season & Weather Guide
A tiny late-summer window (mid-August to September) is the only safe period to dodge deadly monsoons and winter blizzards.
Seasonal Verdict
The pass opens very late due to its high altitude and geographic positioning. The only safe and viable window is from mid-August to late September. Any earlier invites avalanche risk; any later invites severe blizzards.
