The best time to visit Tsomgo Lake, also known as Changu Lake, in Gangtok, Sikkim, is between the months of October to May. During these months, the weather is usually pleasant, which makes it ideal for tourists to enjoy the pristine beauty of the lake and its surrounding areas. The month of October is particularly spectacular as the autumn season sets in and the lake is often clear and the reflections of the surrounding hills on the water create a mesmerizing view. The clear skies also offer breathtaking views of the surrounding peaks. However, if you wish to witness the lake in its frozen state, then January to March is the best period to visit. During winter, the entire landscape is covered in snow and the lake is frozen, offering a unique experience altogether.
In the spring months, specifically April and May, the region around Tsomgo Lake comes alive with a riot of colors with the blooming of flowers like rhododendrons, blue and yellow poppies, and various other species. While the weather is typically mild during these months, visitors should be prepared for the occasional rainfall as the region transitions into the monsoon season. It is essential to check weather conditions before planning your trip as the area can experience occasional landslides or roadblocks during the rainy season. Regardless of the season, it is advisable to carry warm clothing as the lake is situated at a high altitude and the weather can be unpredictable.
