September to March are the best months to visit Sundarbans, the winters being the most pleasant period in the region. Summers can be pretty hot and with temperatures and humidity increasing as the months roll on, but can accommodate travel to some extent. The monsoons bring heavy and long showers which makes travelling somewhat difficult but does see tourists who can brave the rains.
Winter is the ideal time to witness the beauty of the Sundarban National Park. While summers and monsoons are accompanied with blistering heat and humidity, the climate in the winter months is quite pleasant and even provides relief to the animals living in the premises. This is the best time to explore the forests and experience the natural beauty of the region. This also means that there is more chance for visitors to spot the animals and bird species as they come out of hiding. The famous boat safari is also a possibility as the river is not over flooded and therefore not dangerous. The temperatures during the winter season range from 10 degree Celsius to 30 degree Celsius, which is doubly good for tourists as they can walk around and participate in activities without worrying about the climate.

Sundarbans in Monsoon (June - October)
The monsoons months of June to September are laden with heavy rains. The monsoon rains bring back life to the delta after the scorching summers. This makes the mangroves, which are another famous attraction of the park, thrive and rejoice in the showers. The animals as well get relief from the summer heat by way of the rainfall during these months. The temperatures also drop down to a pleasant 25 to 35 degree Celsius. However, one of the main disadvantages of visiting the Sundarban National Park in the monsoon months is the fact that the river, which is the primary mode of transport to the park, is overflowing with rainwater. This makes it extremely risky for transportation and access to the park premises, and hence, monsoons are not ideal to visit the park. Sundarbans National Park in Monsoon Source
Sundarbans in Summer (March-May)
The summers in the Sundarban National Park area is hot, humid and all around uncomfortable. Most visitors and locals alike tend to avoid this season for visiting the park. The temperatures in the summer months range from 30 to 42 degree Celsius. There is a dearth of water in the region in this season too. Tremendous heat waves also accompany these temperatures. All of these factors together make the animals, especially the tigers; take shade in the high trees which makes them invisible to the naked eye.
