Weather in Sikkim

Picking the right time of the year to visit Sikkim is vital, or your primary reason for travelling to this tiny Indian state - the mountains - will be rendered futile. Your best bet is to plan a trip between late September and mid-November, when the fury of the monsoons has abated and the winter is yet to set in. Weather apart, autumn is also the season to witness some of Sikkim's fabulous festivals. In April and May the weather in Sikkim is also relatively good for exploring the state's natural treasures. This is when the state's official flower, the rhododendron is in full bloom across mountainsides. Pack light woollens for use even during these less chilly seasons.

We're here to answer any questions about the best time to visit Sikkim and are happy to recommend hotels in Gangtok.

Summer, between May and October, coincides with the monsoon season, with heavy, prolonged showers often lasting for days on end. This is followed by a brief autumn season from September to October before the bitterly cold winter sets in from around end November to February.

The maximum summer temperature in Sikkim is a very pleasant 28 °C (83 °F), but the heavy rainfall pretty much rules out travel during this time. Minimum winter temperatures dip to 0 °C (32 °F). By end November, valleys like Tsopta and Yumthang are already freezing.

Although the Sikkim climate has three marked seasons, year round rainfall (an astonishing 325 cm/128 in per annum) and a pervasive dampness often play spoilsport. It's also the reason for the existence of a thriving population of leeches!
