Climate & seasons
Most of West Bengal is low delta country running down to the Bay of Bengal, while the far north rises into the Himalayan foothills around Darjeeling, which stay much cooler. On the plains, summer is hot and humid and peaks in April and May, with Kalbaishakhi thunderstorms on many spring afternoons. Most of the year's rain falls from June to September, heaviest in July and August, and cyclones from the Bay occasionally reach the coast.
When to visit West Bengal
The most comfortable months to visit the plains are November to February, when the air is drier and the days mild; December and January are the coolest months. Darjeeling and the hills are at their best in spring and autumn.
