Cold Winters in the month of November to February with minimum temperatures dipping to 4 centigrade during January - February. It is between the month of March and early May when sunshine is quite abundant. Though summer is officially from May to October, Sikkim is almost always wet due to the heavy monsoons, with rains at times continuing for days on ends. Longest recorded nonstop rain is 11 days. September to October is autumn.
A peculiar feature of Sikkim weather is that though there is a classification of sorts of the various seasons, actually experiences a cold winter from end of November to February and monsoons throughout the year with a little respite during May - June and October - November. Even the winter months can be irritatingly wet and damp with the unpredictable showers.
