The answer depends on your travel preferences, weather conditions, and what kind of experience you are looking for. In this detailed seasonal guide, we’ll break down every aspect of Sundarban travel month by month, season by season – so you can plan a perfect trip in 2025 and beyond.

Why Does Season Matter in Sundarban Travel?

Unlike typical tourist spots, Sundarban has dramatic seasonal variations. A tour in June feels entirely different from one in December.

Here’s why:

Weather Impact: Hot summers may limit your comfort, while heavy monsoon rains can make boat rides risky.
Wildlife Behaviour: Animals behave differently depending on the season – in dry months, they gather near water, while during monsoon they retreat deeper into the jungle.
Photography & Scenery: From misty winter mornings to lush green monsoon landscapes – every season has its own charm.
Tour Costs & Availability: Winter is peak season, meaning high demand and higher prices, while monsoon offers budget deals.

So, choosing the right season is the difference between an average trip and a memorable, once-in-a-lifetime experience.
