Visiting Nathula Pass, a high-altitude mountain pass located in the Eastern Himalayas in Sikkim, India, is highly dependent on weather conditions, which can change rapidly at such elevations. The most favorable time to plan your trip is during the summer months, from May to October. During this period, the temperature is relatively moderate, with daytime temperatures ranging from 10°C to 15°C, making for a pleasant travel experience. The skies tend to be clearer, providing spectacular views of the surrounding mountain ranges. It is important to note that Nathula Pass, situated at around 14,140 feet above sea level, remains closed to tourists on Mondays and Tuesdays for maintenance works.
Travel during the monsoon season, which stretches from late June to September, is typically discouraged due to the risks of landslides and poor road conditions. Moreover, the region is prone to heavy fog, reducing visibility considerably. The winter months, from November to April, witness extreme cold with temperatures well below freezing, snowfall and icy conditions on the roads, making them inaccessible at times. If you are particularly interested in experiencing snow, late October to December can be considered, but it's imperative to check the accessibility of roads and pass closures due to snow. Always ensure to check the latest weather forecasts and the political situation before planning your trip, as Nathula is also a sensitive border area between India and China.
