Rainfall is likely to be below normal over the country, it said.
Besides, one to two Low Pressure Systems are likely to form over the Bay of Bengal and one of them may intensify into a depression or cyclone.
It also predicted five to seven days of light or moderate thunderstorms with hail and one to three days of severe thunderstorms with hail at places over the country during the period.
Day and night temperatures are likely to be above normal over the country.
A meeting was held on 27 March with an expert team for providing Long Range Weather Forecast at Storm Warning Centre, Dhaka with a hybrid platform, it said.
BMD forecasts the weather of April after appropriate analysis of weather observations, weather patterns of the upper level, different types of atmospheric weather charts, climate model, SOI (El Nino & La Nino condition), and the weather forecast of April 2025 from the World Meteorological Organization (WMO) recognised institutes, Global Producing Centers (GPCs), ECMWF, JMA, NOAA, IRI-Columbia University, APEC Climate Centre (APCC), RIMES and C3S etc, it added.
The water flow of the main rivers may be normal in this month.
The water levels of the rivers in the northeastern region of the country may increase rapidly due to moderate to heavy rainfall in the northeastern region and adjacent catchment areas during the second half of this month.
The water flow of the main rivers may be normal elsewhere over the country, said the Met office.
Bangladesh, already grappling with a range of climate-induced challenges, now faces heightened risks from intensifying heatwaves.
In 2024, heatwaves with temperatures soaring above 42°C have forced authorities to shut down schools nationwide, affecting the education of an estimated 33 million children.
