The Bangladesh Meteorological Department has forecast that May will experience normal rainfall, following April’s 75 percent above-average precipitation. The long-term outlook indicates that rainfall may decrease during June and July due to less active monsoon winds. The department also expects intermittent rain until May 10, with temperatures remaining normal before gradually rising. A heatwave is likely to begin around May 15 and last six to seven days.

Meteorologist Kazi Zebun Nesa explained that early western low pressure and the upward movement of southern winds caused heavy cloud formation over the Sylhet and Chattogram hill regions, leading to higher-than-usual rainfall before the monsoon. The forecast also mentions one to two low-pressure systems in May, with a low chance of cyclone formation, and five to six nor’westers, including two to three severe ones.

April recorded the highest rainfall in Barishal division, 169 percent above normal, while Dhaka saw about 80 percent more rain. The department noted that this year’s heatwaves were shorter and less intense than in 2023 and 2024.
