Delhi Weather: Rain and Cooler Temperatures Expected

The wider picture

The rainfall expected in Delhi is part of a western disturbance system, a weather pattern typical for this time of year in northern India. As the capital experiences high daytime temperatures reaching around 33°C, the Indian Meteorological Department (IMD) has issued a yellow alert for March 18-20, warning residents of potential weather disruptions. This alert encourages citizens to remain cautious while commuting or planning outdoor activities during this period.

Starting March 18, 2026, the IMD forecasts rain accompanied by thunderstorms and gusty winds. This change in weather is anticipated to bring temporary relief from the sweltering heat, with daytime temperatures expected to drop to around 29°C on March 19. Nighttime lows are projected to be around 19°C, offering a cooler respite for residents.

On March 20, temperatures are likely to decrease further, with maximums expected to reach 27°C and minimums dropping to 17°C. This shift in temperature is a welcome change, especially as the average precipitation in Delhi on March 19 is forecasted to be around 9.4 mm, marking it as the wettest March since 2023.

Mahesh Palawat, a meteorologist, noted that the current western disturbance is positioned over North Pakistan and adjoining Jammu and Kashmir, which is causing heavy rainfall in the western Himalayan regions. He also mentioned that the pre-monsoon activity has arrived earlier than usual, indicating a significant shift in the seasonal weather patterns.

After the rainfall, Delhi’s air quality index (AQI) is expected to improve, with reports indicating that it could drop to 137, falling into the ‘moderate’ category. This improvement in air quality is a positive outcome for residents who have been dealing with the adverse effects of pollution in the city.

Interestingly, the weather has created an unusual overlap of winter-like mornings and pre-summer afternoons. Fog was reported in Delhi due to a mix of rain-soaked air and overnight cooling, with minimum temperatures dropping sharply to 13°C. This phenomenon has left many residents surprised by the sudden change in weather.

Looking ahead, the IMD predicts that another spell of rain could hit the capital early next week, further altering the weather dynamics in the region. As temperatures in Delhi are currently running below what is typical for late March, residents are advised to stay updated on weather forecasts and prepare for the changes ahead.
