Average temperature across Bangladesh in March.
Rangpur, Rajshahi, Dinajpur
Crispness fades quickly as pre‑summer sun intensifies; daytime heat steps up into the mid-to-high 20s°C and fields begin to brown. Farmers prepare for irrigation and the river sandbars rise; dust storms are possible on exposed roads near the Himalayan foothills. It’s a shoulder season for visitors - quieter hotels and cheaper trains - but bring sun protection and light, breathable clothing for long walks.
Dhaka, Mymensingh, Gazipur
The transition to summer becomes clear in March when humidity creeps up and afternoon temperatures frequently hit the high 20s°C. Flowers and early mangoes appear in markets around Gazipur, and Pahela Boishakh preparations begin in earnest. Traffic is dry but thick; if you are planning river trips to Sonargaon or nearby rural spots, late afternoons are best to avoid heating and congested city travel.
Sylhet, Srimangal, Bandarban, Chittagong Hill Tracts
The shift toward summer brings a noticeable rise in humidity by March, though the hills stay cooler than the plains; daytime highs reach the mid-to-high 20s°C. Rhododendrons and early blossoms appear on higher paths, and this is the start of the trekking season in the Hill Tracts before the heavy rains. Roadside tea stalls become lively; carry a rain shell for sudden showers at altitude.
Khulna, Sundarbans, Kuakata, Patuakhali
The onset of spring is noticeable in March as temperatures edge into the high 20s°C and tidal creeks warm; migratory birds may still be present in the Sundarbans. Local markets in Patuakhali and Dhanmondi fill with fresh catches and preparations for Pahela Baishakh start on the coast. Expect hotter afternoons and increase in humidity; keep water and sun protection for beach walks.
Southeast coast, Teknaf, Himchari
March sees the air warming and the sea staying inviting; daytime highs rise into the high 20s°C and vendors set up more beachfront services. This is a good time for longer boat trips and for visiting nearby attractions like Inani Beach and Ramu’s Buddhist temples. Expect increasing local weekend crowds and bring sun protection for long riverbank and shore excursions.
Independence Day on March 26 is observed nationally with ceremonies and public events.
