The best time to visit Chungthang and Lachung in Sikkim is during the spring season, which spans from late February to May. During this period, the weather is pleasant with moderate temperatures that typically range between 10°C and 20°C. This is an excellent time for sightseeing, as the places are in full bloom with a variety of wildflowers, including rhododendrons adding a splash of color to the landscape. The clear skies also provide great opportunities for photographers and nature lovers to capture the beauty of these regions. Moreover, the pre-monsoon climate makes it ideal for trekking and other outdoor activities in the lush green valleys.
Another favorable time to explore these Northern Sikkim destinations is in the autumn, which lasts from October to November. During autumn, the monsoon rain has passed, leaving a fresh and clear environment. The weather is cool, and this short window offers breathtaking views of the snow-capped Himalayan peaks before the onset of winter. As temperatures start to dip, visitors can enjoy the serene beauty of the regions without the worry of heavy snowfall that is common in the later months. It's important to note that as winter approaches, roads may start getting blocked due to snow, especially from December to January, so planning your visit within this autumn timeframe is essential for a trouble-free experience.
