Mumbai, August 19, 2025 — The India Meteorological Department (IMD) has issued an orange alert for Mumbai on Wednesday, August 20, forecasting heavy to very heavy rainfall accompanied by gusty winds reaching speeds of 45–55 kmph. After several days of extremely heavy rainfall, the city is expected to continue experiencing severe weather conditions that may cause significant disruptions across the metropolitan area.
According to multiple weather sources, Mumbai will see temperatures ranging from approximately 26 to 27 degrees Celsius, with a high likelihood of heavy rain accumulating up to 122 mm on August 20. The swollen reservoirs supplying drinking water to the city are near critical levels, with water storage surpassing 90% capacity. The ongoing monsoon saturation has already resulted in waterlogging, traffic jams, and delays affecting local transport systems, including the suburban railway network and road traffic.
Due to the prevailing extreme weather, the Maharashtra government is closely monitoring the situation. A school holiday on August 20 is highly probable, with a 70% chance in Mumbai and adjacent districts expected to be affected as well. The final decision is subject to the rainfall conditions overnight on August 19 and early morning hours of August 20. The district collector will announce definitive school closure status early Wednesday morning.
Maharashtra Chief Minister Devendra Fadnavis has urged citizens to stay cautious during this period of intense rainfall and warned of heightened flood risks, particularly during the high tides scheduled for the day. The IMD alerts and local government advisories emphasize public safety and recommend minimizing unnecessary travel to avoid congestion and hazards caused by waterlogging.
In summary, heavy rainfall and strong winds are forecasted for Mumbai on August 20, with substantial impacts on daily life. A likely holiday for schools aims to prioritize safety for students and families amid disrupted transportation and flood-prone conditions. Residents are advised to stay informed through official weather updates and follow municipal guidance.
