The wider picture
Delhi’s weather is about to shift dramatically as the Indian Meteorological Department (IMD) forecasts rain starting March 18, 2026. This weather change comes on the heels of high daytime temperatures, which have been hovering around 33°C. The impending rain is expected to bring thunderstorms and gusty winds, prompting the IMD to issue a yellow alert for the capital from March 18 to March 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. Rainfall is anticipated to provide temporary relief from the sweltering heat, with daytime temperatures expected to drop to around 29°C on March 19, accompanied by nighttime lows of 19°C.
On March 20, temperatures are predicted to decrease further, with maximums likely reaching only 27°C and minimums dropping to 17°C. This significant drop in temperature is a stark contrast to the highs experienced earlier in the month and is indicative of the unusual weather patterns affecting the region.
Historical data reveals that the average precipitation in Delhi on March 19 was recorded at 9.4 mm, marking it as the wettest March since 2023. The maximum temperature recorded on that day was 26.8 degrees Celsius, the lowest so far this month. Such fluctuations in temperature are not uncommon during this period, as the region often experiences the effects of western disturbances.
Mahesh Palawat, a meteorologist, noted that the western disturbance is currently positioned over North Pakistan and adjoining Jammu and Kashmir, causing heavy rainfall in the western Himalayan regions. He also mentioned that the pre-monsoon activity has arrived earlier than usual this year, contributing to the current weather conditions.
In addition to the rain, Delhi’s air quality index (AQI) improved to 137 in the ‘moderate’ category following the rainfall. This improvement is a welcome change for residents who have been grappling with poor air quality in recent months. Fog was also reported in the city, attributed to a mix of rain-soaked air and overnight cooling, creating an unusual overlap of winter-like mornings and pre-summer afternoons.
As temperatures continue to run below what is typical for late March, the IMD predicts another spell of rain could hit the capital early next week. This ongoing weather pattern suggests that residents should remain prepared for further fluctuations in temperature and weather conditions in the days ahead.
Overall, the upcoming rain and cooler temperatures are expected to bring a much-needed respite from the heat, but residents are advised to stay informed about the latest weather updates and alerts from the IMD.
