Delhi-NCR Weather Update: Rainfall in the Delhi-NCR region on Wednesday morning brought a cool breeze, making the weather pleasant. An active western disturbance caused temperatures to drop and visibility to remain low throughout the day. The India Meteorological Department (IMD) has indicated that the rain will now subside, but minimum temperatures are expected to drop further.
According to the Meteorological Department, light rain occurred between 2 a.m. and 5 a.m. on Wednesday morning, and heavy rain was recorded between 2:30 p.m. and 5:30 p.m. During this period, the sky remained overcast. This rainfall also directly impacted flight operations—nearly 100 flights were delayed and 15 were diverted to nearby airports. Of these, eight were diverted to Jaipur, five to Lucknow, and two to Chandigarh. A flight is considered “delayed” if it is delayed by 15 minutes or more.
According to IMD data, the capital has recorded a total of 80.5 mm of rainfall this month, compared to the average October rainfall of just 15.1 mm—a figure that indicates rainfall has been nearly five times higher than normal.
In comparison, the city received no measurable rainfall in October last year, while 5.4 mm was recorded in 2023 and 128.6 mm in 2022.
According to meteorologists, the root cause of the rain was an induced low-pressure area active over northern Rajasthan and Haryana, associated with an upper cyclonic circulation extending up to about 9.6 kilometers above sea level. This system was tilted northwestward with height. The IMD forecasts that the impact of this system will diminish by Wednesday.
Regarding visibility, visibility in the Palam area was around 6,000 meters at 1:30 pm, which dropped to just 1,200 meters by 5 pm.
In conclusion, it’s fair to say that this wave of rain and cold was unusual for Delhiites, as such rainfall is rare in October. However, it’s also true that such activity is occasionally triggered by western disturbances. The weather will remain relatively clear over the next few days, but caution is advised regarding minimum temperatures.
