About Gangtok weather
Gangtok is one of many towns in Sikkim's steep Himalayan terrain, where conditions range from subtropical valleys to alpine peaks within short distances, in Sikkim, India. Before the rains arrive, there's a mild summer in the lower valleys, cool-to-cold at higher elevations. After that, Gangtok sees a heavy south-west monsoon (June–September) that raises landslide risk on mountain roads. By December, expect a cold winter (December–February) with regular snow at higher elevations, including around Gangtok.
