Delhi recorded a minimum temperature of 23.2 degrees Celsius, and the city's air quality index stood at 171, in the 'moderate' category, according to a local report. Sensitive groups should still limit prolonged outdoor exertion.

The expected rain from October 6 could be a temporary cleanser for the city's air. Weather alerts forecast thunderstorms and rain in the capital through October 7, which may wash out pollutants and push the AQI lower.

If the rain is light or delayed, the AQI could creep back toward 'poor' levels. Real-time monitors showed some stations in the unhealthy range on Monday morning, underscoring how uneven the city's air remains across neighbourhoods.

For now, Delhi is enjoying a rare moderate day. But the broader seasonal trend points to tougher air ahead, when stubble burning and festive emissions typically push the city into the 'very poor' zone. Residents can breathe a little easier, but not for long.
