About Mangan weather
Mangan is one of many towns in Sikkim's steep Himalayan terrain, where conditions range from subtropical valleys to alpine peaks within short distances, about 21 km north-west of Gangtok. Conditions turn hot with a mild summer in the lower valleys, cool-to-cold at higher elevations. Rain arrives with 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.
