Average temperature across Bangladesh in December.
Rangpur, Rajshahi, Dinajpur
A return to clear, crisp winter conditions closes the year; daytime highs sit in the high teens to low 20s°C while nights drop to near 10°C. This is prime time to visit orchards around Chapainawabganj and the mango relics of Rajshahi short of the summer crush. Expect lively markets, dry roads and reliable transport - pack a warm layer for early mornings and river fogs that may linger in low areas.
Dhaka, Mymensingh, Gazipur
December returns cooler mornings and mild days, with low rainfall and festive urban energy as people prepare for year-end holidays. Nights can be pleasantly chilly at 12-15°C; a light jacket is useful for rooftop dining. This is peak time for foreign visitors, so expect higher prices and crowded hotels, but travel logistics around Dhaka are typically the most reliable all year.
Sylhet, Srimangal, Bandarban, Chittagong Hill Tracts
December is cooler, with fresh nights and mild daytime temperatures - a fine month for trekking the easier hill routes and for visiting the Sylhet tea country. Festivals and holiday travel increase, so expect more bookings around popular lodges. Pack layers for cold dawns on ridge walks and bring insect repellent for lower-elevation forested sections where mosquitoes may persist.
Khulna, Sundarbans, Kuakata, Patuakhali
December cools and dries further; mornings can be crisp on the beach and the low humidity makes outdoor photography and boat trips enjoyable. Holiday travel picks up, especially over end-of-year weekends, so popular Sundarbans boat tours fill quickly. Pack light layers for early dawns on deck and a windproof layer for blustery evenings along the exposed coast.
Southeast coast, Teknaf, Himchari
December cools to comfortable levels with low humidity, making it one of the most pleasant months to visit Cox’s Bazar and St. Martin’s. Daytime temperatures sit in the low-to-mid 20s°C and nights can be breezy; family travel picks up around the holidays. Book early for beachfront rooms and expect crowds, but also reliable boat services and clear water for late-year snorkels.
Victory Day on December 16 commemorates Bangladesh's 1971 independence and is marked by formal ceremonies and memorial events.
