West Bengal
A tea plantation in Western Dooars, northern West Bengal, India.
In West Bengal, the monsoon seasonāreferred to as the hot and wet seasonāoccurs from mid-June to September. During this period, rain-bearing monsoon winds blow from the southwest, bringing significant precipitation to the state.1
While this timeframe defines the primary wet season, it is important to note that the state also experiences pre-monsoon activity in April and May, known as Kalbaisakhi or Nor'westers, which bring thunderstorms and rain.2
