April brings hot, humid weather and frequent afternoon thunderstorms toward the end of the month as pre-monsoon activity increases. Heat can be intense in inland and northern areas, so plan daytime activities accordingly.

Average temperature across Bangladesh in April.
Rangpur, Rajshahi, Dinajpur
The atmosphere turns sultry by April and the infamous Nor’westers (kalbaishakhi) begin to pop up across the plains. Temperatures routinely hit the low-to-mid 30s°C and sudden late‑afternoon thunderstorms offer dramatic relief and occasional small hail. Pahela Baishakh (Bengali New Year, mid-April) livens up towns - expect crowds in Rajshahi and special markets - and pack both sunblock and a thin rain jacket for the unpredictable storms.
Dhaka, Mymensingh, Gazipur
April is raw heat - Dhaka can feel stifling with highs in the low-to-mid 30s°C and the notorious pre-monsoon nor’westers bringing sudden, dramatic thunderstorms. These storms give brief relief and often knock out power locally; keep a small umbrella and expect rain-wash smells on the street. If you want to see Bengali New Year festivities, mid-April is vibrant but intensely hot, so plan early-morning events.
Sylhet, Srimangal, Bandarban, Chittagong Hill Tracts
April heats up in the valleys and the plains surrounding the hills, with the lower elevations touching the low 30s°C and afternoon Nor’westers sometimes sweeping down into the hills. Mornings remain pleasant for sunrise at Nilgiri or Sajek, but afternoons can feel sultry. Bengali New Year events are colorful in Sylhet town; pack light clothes and expect brief but intense storms toward late afternoons.
Khulna, Sundarbans, Kuakata, Patuakhali
April can feel hot and muggy along the coast with daytime temperatures commonly in the low 30s°C, while sudden Nor’westers bring sharp thunderstorms that cool the air. Cyclone risk rises in the pre-monsoon window - keep aware of local advisories if you are taking overnight boat trips. Kuakata gets busier around holidays; early morning is the best time for comfortable beach exploration.
Southeast coast, Teknaf, Himchari
April becomes noticeably hotter and more humid, and the risk of pre-monsoon nor’westers increases, occasionally causing afternoon squalls that roughen the sea. Pahela Baishakh festivities add local bustle in seaside towns, but beach comfort declines mid-day. If you plan to visit St. Martin’s, check boat schedules closely and be prepared for last-minute cancellations due to stormy conditions.
Bengali New Year (Pohela Boishakh) on or around April 14 is celebrated with cultural fairs, processions and traditional performances.
