The best time to visit Char Dham (Sidheshwar Dham) in Namchi, Sikkim is generally during the months of March to June and September to November. During these months, the weather is usually pleasant with clear skies and a comfortable climate, making it an ideal time for sightseeing and temple visits. The temperature ranges from 10°C to 28°C. This is the spring to early summer season when the natural beauty of Sikkim is in full bloom with rhododendrons and other flowers, and in autumn the clear skies offer stunning views of the Himalayas.
Monsoon season, from July to August, is not recommended for visiting as the region experiences heavy rainfall, which can lead to landslides and travel disruptions. However, the winter months from December to February can also be enchanting for those ready to embrace the cold. The region often sees snowfall, and while the temperatures can be quite chilly, ranging from -3°C to 15°C, the clear winter skies offer breathtaking views of the snow-covered peaks. But do note, some facilities may be limited in the off-season due to the cold weather conditions.
