Bangladesh Meteorological Department (BMD) forecasted in the monthly weather outlook that Short-term flooding may occur in the northern, northeastern, and southeastern regions of the country due to monsoon heavy rainfall.<\/p>\n
It also says, the water level of the major rivers of the country may increase overall in September, while rainfall is likely to be below normal all over the country.<\/p>\n
“1-3 Low Pressure Systems are likely to form over the Bay of Bengal and one of them may intensify into a Monsoon Depression,” said the Long Range Weather Forecast for September 2026 issued recently.<\/p>\n
Thunderstorms are likely to occur on 3-5 days over the country during this month. Both day and night temperatures are likely to remain above normal over the country.<\/p>\n
Two to three mild (36-37.9)\u00b0C to (38-39.9)\u00b0C moderate heatwaves are likely to occur over the country during this month.<\/p>\n
A meeting of the Expert Team on Long-Range Weather Forecasting was held on 01 September 2026 at the Storm Warning Centre in Dhaka.<\/p>\n
During the meeting, various data and information for August 2026 were analysed .<\/p>\n
According to official data, normal rainfall (-5.7%) was recorded over Bangladesh during August 2026. Rainfall was recorded above normal at Chattogram and Mymensingh divisions, normal at Sylhet and Barishal divisions, and below normal elsewhere over the divisions.<\/p>\n
During August 2026, four low-pressure areas formed over the Bay of Bengal, two of which intensified into Monsoon Depressions.<\/p>\n
Due to the active southwest monsoon and the influence of the Well-Marked Lows and Monsoon Depressions, heavy to very heavy rainfall occurred at many places across the country during the month.<\/p>\n
The rainfall was also accompanied by gusty and squally winds and thunderstorms.<\/p>\n
The highest daily rainfall of the month was 198 mm, recorded at Hatiya on 5 August 2026.<\/p>\n
A mild heatwave affected some areas of the country during 10-12, 22, & 26-30 August 2026. The highest maximum temperature of the month was 37.0\u00b0C, recorded at Rajshahi on 27 August 2026, while the lowest minimum temperature was 22.6\u00b0C recorded at Narayanganj on 7 August 2026.<\/p>\n
The monthly maximum, minimum, and mean temperatures were above normal by 0.8\u00b0C, 0.5\u00b0C, and 0.7\u00b0C, respectively.<\/p>\n
Overall, rainfall, observed temperature, heatwave conditions, thunderstorm activity, agro-meteorological conditions, and river conditions during August 2026 were generally consistent with the monthly weather outlook.<\/p>\n
