The ideal time to visit Kinner Kailash in Kinnaur, Himachal Pradesh, is during the summer months from May to June and the post-monsoon period from September to October. During these months, the weather is generally pleasant and conducive for trekking. The summer season ensures that the snow from winter has melted, providing a clearer path for trekkers. However, daytime can be a bit warm with temperatures ranging from 8°C to 30°C, so it's always a good idea to carry some light woolens for the evenings when the temperature may dip.
The post-monsoon season, which typically lasts from the end of September to October, offers a respite from the rains and the landscape is vibrant with lush greenery and clear skies. Although the temperature starts dropping, it is still comfortable for outdoor activities. During this time, the weather stays stable with fewer chances of rainfall, thereby reducing the risks of landslides and making it safer for trekkers and pilgrims. The temperature tends to hover between 5°C and 20°C, rapidly dropping as winter approaches. Hence, warm clothing is essential for anyone visiting Kinner Kailash during the autumn.
