Karakoram Highway

Weather

The most pleasant temperatures for KKH travel are in May, June, September and October. July and August get uncomfortably hot along most of the KKH, except in high-altitude trekking zones.

In northern Pakistan the wettest months are during the monsoon, from late July to early September, with random summer storms from Hunza southwards, and steady rain and high humidity from Indus Kohistan and the Kaghan Valley southwards. These monsoonal regions are also sporadically drizzly from December to March. The driest months are May and June and mid-September to November, with the clearest skies in autumn. Xinjiang remains extremely arid all year long, with a trace of rain in summer.

From Gilgit to Kashgar, winter is long and cold (often well below freezing), especially in January and February, and snow closes many high passes, including the Khunjerab.
