Lightning Risk

July to September provides the optimal window as the Markha Valley sits in a rain-shadow, avoiding monsoon impact. Consolidated snowpack and stable weather are critical for navigating the bergschrund, steep 55-65 degree ice headwall, and the exposed knife-edge summit ridge.
Season at a Glance
Editor's Notes
Book for late August or early September. The night freeze hardens the ice on the ridge, giving your crampons far better purchase than the soft midday slush of July.
