IMD’s Weather Forecast and Alerts
The IMD has explained the present weather conditions due to a monsoon trough extending from Suratgarh to the northeast Bay of Bengal, and the presence of an upper-air cyclonic circulation over Himachal Pradesh and Punjab at an altitude of around 1.5 km above sea level. It has also forecasted light to moderate rain, thunderstorms, and lightning to continue in Delhi-NCR until July 12, 2025, with temperatures between 31 °C and 33 °C, a minimum of 22.9 °C, which is cooler than in recent days.

Air Quality Improvement
A great benefit of the rain is the improvement in air quality in Delhi. On July 6, 2025, the Air Quality Index (AQI) reported a value of 88 (moderate), mainly due to the recent rainfall (AQI.in). This represents a significant improvement over the city’s ordinary air quality, which should come as a relief, especially for those who are particularly susceptible to these contaminants.
Precautions and Advisories
As the rain continues, precautionary alerts and public safety advisories have been made. The application for positions at the Delhi airport has now recommended that people use public transportation, i.e., the metro, due to significant road congestion in getting to the airport, which may affect maintaining a flight schedule. People are being advised to refrain from travel in waterlogged areas, stay indoors during thunderstorms, and keep emergency kits ready. Checking flight statuses and making allowances for extended travel times can also reduce some of the interruptions we are all facing.

Regional Weather Context
Rainfall in the Delhi-NCR region is one component of a larger monsoon weather system that spans Northwest India. Himachal Pradesh has faced severe consequences of the monsoon, including landslides and flooding, which resulted in 75 official fatalities due to rain-related incidents. Although Delhi-NCR has not suffered severe consequences, the connection and interaction of weather patterns remind us of the current monsoon, for which we need to be prepared across the region.
Delhi-NCR experiences heavy rainfall, which improves air quality and brings down temperatures, but also causes significant disruptions. Residents are urged to remain alert until the monsoon season passes in mid-July.
