May and June offer the most stable pre-monsoon conditions for the heavily crevassed approach. September and October provide optimal visibility but colder conditions for the exposed summit ridge. The monsoon brings extreme objective hazards.
Season at a Glance
Editor's Notes
June is the finest month. The Tentu La ice is at its most consolidated after winter freeze, and you have the longest daylight hours — critical for a safe summit return on a Grade D route.
