Bangladesh in December

November through March offers the sweet spot – cool, dry weather perfect for exploring. Temperatures hover around 70-80°F with minimal rain. This is peak season, so book accommodations early, especially in Dhaka and Chittagong. April and May bring intense heat – we're talking 95°F+ with crushing humidity. Only visit during these months if you handle heat well and want to avoid crowds. Some attractions reduce hours or close midday. Monsoon season (June-October) transforms the country. Rivers swell, rural areas flood, and transportation becomes unpredictable. But the landscape turns emerald green, and you'll have tourist sites mostly to yourself. Just pack serious rain gear and build flexibility into your itinerary. The Sundarbans actually become more accessible during early monsoon when water levels rise.
