Sikkim, as a state, encompasses various elevations and climates, so the temperature can vary depending on the specific location and time of year. In general, Sikkim has a wide range of temperatures, from subtropical in the lower regions to alpine in the higher areas.
Darjeeling, on the other hand, is known for its cooler climate due to its higher elevation. It's a hill station located at an altitude of around 6,700 feet (2,042 meters) above sea level, and its climate is considered more temperate compared to many parts of Sikkim.
In terms of general temperature comparisons:
Darjeeling: Darjeeling tends to be cooler than the lower-altitude areas of Sikkim. Summers in Darjeeling are mild, with daytime temperatures ranging from 15°C to 20°C (59°F to 68°F). Winters are colder, with temperatures dropping to around 2°C to 7°C (36°F to 45°F). It can occasionally experience snowfall during the winter months.
Sikkim: The temperatures in Sikkim can vary widely based on the elevation. In places like Gangtok (the capital of Sikkim) at a lower elevation, the temperatures are milder and more moderate, similar to Darjeeling. However, in higher-altitude areas of Sikkim, such as Lachung, Lachen, or areas around Nathula Pass, temperatures can be significantly colder, especially during the winter months, often dropping below freezing.
