• Delhi's air quality has deteriorated sharply, with AQI readings reportedly exceeding 400 and some reports indicating levels above 500.

The capital city is catching up with the festivities of Diwali. Weather conditions are quite comfortable, with slight warmth in the afternoon and a pleasant nip in the air during late night and early morning. The day and night temperatures have been hovering around 29°C and 16°C, respectively. Base station Safdarjung normally drops to about 13°C around the mid-month mark of 15th Nov. The minimum temperature lowers to about 11°C by 23rd Nov and 10°C by the fag end of the month. Single-digit minimum temperatures are not alien during the last week of November. Last year, the lowest temperature was 8°C on 26th Nov. The day temperatures are running below normal by about 2°C and have remained confined to under 30°C so far. In the past, the maximum temperature has quite often crossed 32°C during the first week of the month. However, the maximum so far has been arrested at 29.8°C, recorded yesterday.

A western disturbance is likely to arrive on 10th Nov, impacting weather conditions over the mountains on 10th and 11th Nov 2026. Later, an induced cyclonic circulation is likely over Punjab and North Rajasthan. The spillover effect on the northern plains is likely on 12th and 13th Nov. Delhi will remain on the outer periphery of the system. However, there is a chance that Delhi/NCR may get light rainfall on these two days.

The pleasant weather conditions have been severely hampered by rising pollution levels. Over the last two days, the AQI breached the 400 mark. Today, conditions have worsened, and there are reports of AQI levels crossing the 500 mark for the first time, quite early in this season. Pollution levels, as such, worsen during the late-night and morning hours due to still wind conditions and a stable atmosphere on account of the inversion layer. These hazardous levels are unlikely to improve and may impact the festivities of Diwali. A concoction of smoke, dust, and trapped emission particles is likely to choke the city and suburbs during this week.
