The wider picture
The rainfall is part of a western disturbance system, typical for this time of year in northern India. The India Meteorological Department (IMD) has forecasted rain starting March 18, 2026, accompanied by thunderstorms and gusty winds. This weather pattern is expected to bring much-needed relief from the high daytime temperatures that have hovered around 33°C.
A yellow alert has been issued for Delhi from March 18 to 20, warning residents of potential weather disruptions. “The yellow alert indicates potential weather disturbances over the next three days, urging citizens to remain cautious while commuting or planning outdoor activities,” an IMD spokesperson stated.
As the rain begins, daytime temperatures are expected to drop to around 29°C on March 19, with nighttime lows dipping to 19°C. By March 20, maximum temperatures are likely to fall further to 27°C, while minimums could reach 17°C. This marks a significant shift in the weather pattern for Delhi.
On March 19, the average precipitation recorded was 9.4 mm, making it the wettest March since 2023. The maximum temperature that day was noted at 26.8 degrees Celsius, the lowest so far this month. Following the rainfall, Delhi’s Air Quality Index (AQI) improved to 137, falling into the ‘moderate’ category.
Fog was also reported in various parts of Delhi due to a mix of rain-soaked air and overnight cooling. Minimum temperatures dropped sharply to 13 degrees Celsius, creating an unusual overlap of winter-like mornings and pre-summer afternoons. “Overnight the sky remained clear, which led to cooling of the ground,” explained Mahesh Palawat, a senior meteorologist.
Looking ahead, the IMD predicts that another spell of rain could hit the capital early next week. Temperatures in Delhi are currently running below what is typical for late March, indicating a shift in seasonal patterns. “The pre-monsoon activity has also arrived earlier than usual,” Palawat added, highlighting the unusual weather trends.
As residents prepare for the upcoming weather changes, officials urge caution and preparedness. The IMD continues to monitor the situation closely, with updates expected as the weather develops.
