The short answer
When to go to Sundarbans
November to February is the best window: dry, clear and cool, with comfortable boat days. October and March are workable, though cyclones remain possible in October and the heat builds in March. April and May are hot and humid, and June to September brings heavy monsoon rain, rough rivers and cyclone risk, so most boat trips are best avoided. Older travellers will find the cool, dry months far easier on long, open-deck days.
