Delhi Air Pollution: Severe Zone Hits Before Diwali

Delhi air pollution is turning the days before Diwali into a health scare, with the capital's air quality index sitting in the very poor band and a dozen monitoring stations tipping into the severe zone on Thursday morning. If you have been scrolling photos of the city wrapped in grey smog, this is the story behind them.

According to The Indian Express, the overall index was three hundred seventy at eight in the morning, with Jahangirpuri the worst spot at four hundred fifty-nine. Punjabi Bagh, Narela, Alipur and Rohini were all above four hundred thirty. Anything between four hundred one and five hundred counts as severe on the national scale.

How bad is the air right now?

The city's average has climbed for days. The Indian Express reported that the reading was three hundred fifty on Tuesday afternoon and three hundred seventy-nine on Wednesday morning, before easing slightly on Thursday. That small dip is not real relief, because the official early warning system expects the air to slide into the severe category on Friday and Saturday.

The picture also depends on who is counting. A private monitoring site put the reading at five hundred fifty-two, but that figure is unofficial and uses different parameters from the national pollution board. Either way, the message is the same: breathing in Delhi right now is rough, especially for kids, older people and anyone with asthma.

Data cited by The Hindu BusinessLine shows how uneven the damage is. Out of fifty-nine stations in Delhi, nineteen sat at four hundred or above at noon, while another nineteen were between three hundred fifty and three hundred ninety-nine. Next door, some sectors of Noida were below three hundred.

Work from home, but traffic did not budge

The regulator for the region, the Commission for Air Quality Management, ordered government and private offices in Delhi and nearby districts to run at up to half their staff in the office. The order covers the period from November fifth to November twentieth, a stretch that has historically seen some of the worst air of the year.

On day one, it did not seem to help much. Delhi, Noida and Gurugram all saw heavy traffic because of festival shopping and the usual office rush, according to The Hindu BusinessLine. One daily commuter, Rajesh Singh, said the jam near Film City was normal for a Thursday morning.

The commission had already brought in the first stage of its graded response plan on October twenty-first and the second stage on November second. Construction limits and other curbs rise with each stage, which is why further tightening is possible if the numbers keep climbing.

The farm fire blame game

Politics is now part of the smog. Delhi's environment minister Manjinder Singh Sirsa accused the Punjab government of misleading people about stubble burning and said smoke from Punjab was drifting toward the capital on winds linked to a western disturbance.

The satellite numbers tell a more complicated story. The Hindu BusinessLine reported that, according to the agricultural research institute's monitoring lab, Punjab recorded two thousand three hundred forty-seven burning cases up to November fourth, compared with two thousand eight hundred thirty-nine in the same period last year. That is a fall of more than seventeen per cent, though farm fires are only one ingredient alongside traffic, dust and festival fireworks.

Will Diwali make it worse?

Diwali falls on Sunday, November eighth, and fireworks are the wild card. Green firecracker sales have resumed in parts of Delhi after a court allowed them, according to a live blog from The Economic Times, though cleaner crackers still release smoke.

Meteorologist Navdeep Dahiya said winds could pick up from under five kilometres an hour to between ten and twenty on Friday and Saturday, which might improve the index by twenty to thirty per cent in the afternoon and evening. He warned that winds could weaken again between November eighth and thirteenth because of an approaching western disturbance, trapping pollutants once more.

The Delhi government is also reportedly preparing artificial rain through cloud seeding if the air worsens after Diwali and Chhath Puja, though campaigners note it only washes the air briefly and does not fix the sources of emissions.

What you can actually do

If you live in the region, check the live index before heading outside, keep windows shut in the early morning and late night when the smog is thickest, and wear a well-fitted mask rated for fine particles if you must travel. Running an air purifier indoors helps, and skipping fireworks helps everyone.

The bigger fix is slower and harder: cleaner transport, less burning and better planning across several states. For more coverage of the planet's biggest stories, browse the climate emergency section, and keep an eye on Delhi air pollution as the festival weekend arrives.
