Rainfall – Delhi Sees Heaviest August Downpour of the Season, Bringing Relief and Disruptions
Rainfall – The national capital experienced its heaviest rainfall of August so far on Thursday, providing welcome relief from persistent heat and humidity while causing significant disruption to daily life across several parts of the city.
Heavy showers lashed many areas throughout the day, leaving roads submerged, slowing traffic for hours, and lowering daytime temperatures considerably. The spell of rain marked the wettest day of the month so far and brought a noticeable change in weather conditions after several humid days.
Rainfall Recorded Across Monitoring Stations
According to the India Meteorological Department (IMD), Lodi Road received the highest rainfall between 8:30 am and 5:30 pm with 60.4 mm. Safdarjung, the city’s primary weather station, registered 56.0 mm, followed by Ridge with 54.4 mm. Ayanagar recorded 22.3 mm, while Palam measured 14.6 mm during the same period.
The IMD also reported cumulative rainfall recorded since 8:30 am at various locations. Lodi Road logged 43.8 mm, Palam recorded 25.2 mm, Safdarjung received 18.7 mm, Ridge measured 17.2 mm, and Ayanagar registered 14.2 mm.
Sharp Drop in Daytime Temperature
The widespread rainfall led to a significant decline in maximum temperatures across Delhi. Safdarjung recorded a daytime high of 27.6 degrees Celsius, which was 6.6 degrees below the seasonal average.
Lodi Road reported a maximum temperature of 27.8 degrees Celsius, 5.2 degrees below normal. Palam registered 27.3 degrees Celsius, nearly 7.1 degrees below average, while Ridge recorded 27.6 degrees Celsius, 6.4 degrees below normal. Ayanagar remained one of the coolest locations with a maximum of 27.2 degrees Celsius, around 6.8 degrees below the usual level.
Waterlogging Hits Major Roads
The intense rainfall resulted in water accumulation across several parts of the city, affecting traffic movement during peak hours. Commuters faced long delays as many important roads remained waterlogged for an extended period.
Areas including Sainik Farms, Shastri Park, Rohtak Road, Tughlaqabad, the vicinity of the Red Fort, and parts of the ITO corridor reported flooding on roads, making travel difficult for motorists and public transport users.
More Rain Expected Over the Coming Days
The weather department has predicted generally cloudy skies accompanied by heavy rainfall on Friday and has issued a yellow alert for Delhi. The forecast indicates that maximum temperatures are likely to remain between 27°C and 30°C, while humidity levels may stay close to 91 percent.
Mahesh Palawat, Vice President for Meteorology and Climate Change at Skymet Weather, said rainfall activity is expected to continue across Delhi and surrounding regions over the next two to three days.
He explained that multiple weather systems are influencing the current conditions, including a western disturbance over the Himalayan region, cyclonic circulations over Uttar Pradesh, Bihar, and the Darjeeling area, an active monsoon trough, and increased moisture flowing in from the Bay of Bengal.
According to Palawat, these combined systems are likely to produce widespread rainfall across the Indo-Gangetic plains, with some places expected to receive heavy showers. For Delhi, light to moderate rainfall is likely to continue until August 10.
Air Quality Remains Stable
Despite the rainfall and changing weather conditions, Delhi’s air quality remained in the “satisfactory” category as of 4 pm, indicating relatively stable pollution levels compared with previous days.
Government Seeks Long-Term Solution for NH-24 Flooding
Recurring flooding on NH-24 also came under official review. Public Works Department Minister Parvesh Sahib Singh directed the National Highways Authority of India (NHAI) to raise the road level to address repeated waterlogging on the highway.
The minister also instructed NHAI officials to prepare and submit detailed reports identifying locations that regularly experience flooding so that permanent measures can be planned before future monsoon seasons.
