The best time to visit Bangladesh, season by season
Winter is the classic travel season, but the monsoon is when the haors, swamp forests and waterfalls come alive. A month-by-month guide to planning your trip.
There is no single best time to visit Bangladesh. It depends on what you want to see. The country has a cool, dry winter, a hot pre-monsoon summer and a long, very wet monsoon, and each opens different places.
The seasons at a glance

Month by month
- November to February: peak season. Saint Martin's Island opens on 1 November, the Sundarbans is at its most comfortable, and the coast and hills are dry. Book hotels early for winter holidays.
- March to May: hot and humid, with storms building in the afternoons. Travel early in the day, and watch cyclone warnings on the coast late in the season.
- June to September: the monsoon. Haors fill, Ratargul floods, and waterfalls in Sylhet and the hills are at their fullest. Roads and sea routes can be disrupted, so keep plans flexible. The Sundarbans is closed June to August.
- October: a shoulder month: rivers are still high, skies clear, and crowds are light.
