Climate
West Bengal's climate varies from tropical savanna in the southern portions to humid subtropical in the north. The main seasons are summer, the rainy season, a short autumn, and winter. While the summer in the delta region is noted for
excessive humidity, the western highlands experience a dry summer like northern India, with the highest daytime temperature ranging from 38 °C (100 °F) to 45 °C (113 °F). At night, a cool southerly breeze carries moisture from the Bay of
Bengal. In early summer, brief squalls and thunderstorms known as Kalbaisakhi, or Nor'westers, often occur.
Geography
Geography of West Bengal, a state in eastern India, is diverse, of high peaks of Himalaya in the northern extremes to coastal regions down south, with regions such as plateau and Ganges delta intervening in between. West Bengal is only
state in India where Himalayas are in the north and sea is at the south, with both plains and plateaus covering the remaining region.
