1/5th of candidates in Bihar fray are scions

Experts have warned that smoke from farm fires in Pakistan could soon affect Delhi’s air. A western disturbance is expected between 27 and 29 October, after which winds from the northwest may carry smoke and dust towards the city. Pakistan has already recorded nearly 6,000 farm fires this month — one of the highest counts in recent years — while Punjab in India has seen fewer fires so far.

Sunil Dahiya from EnviroCatalysts said that slow and changing winds have allowed pollution from nearby areas such as Gurugram, Ghaziabad, Sonipat, and Gautam Buddha Nagar to gather over Delhi, causing a slight rise in pollution levels. Meteorologists added that once winds change, the air quality in Delhi could worsen, with hazy skies and high AQI levels expected.

Role of farm fires in Delhi’s pollution still low, for now

Despite Delhi's severe "very poor" air quality, experts note the usual spike in pollution from farm fires in Punjab and Haryana has not yet happened. Its contribution has been minimal, peaking at just 2.6%, meaning the current smog is from local sources like vehicles and industry. This delay is attributed to floods disrupting the harvest and unfavourable wind patterns, pushing the expected surge in smoke to after October 28th.
