Delhi breathed its best air this year on Saturdaythanks to a combination of overnight rain across the city and lower vehicular emissions owing to restriction on movement due to the G20 Summit.

Water sprinklers deployed to check pollution levels during the international event also likely helped, claimed civic officials, in bringing the air quality index (AQI) to 54. This was also a significant improvement over Friday's reading of 83.

Prior to Saturday, July 29 saw the lowest AQI this year at 59, according to the Central Pollution Control Board (CPCB).

Rainfall in the early hours of Saturday and then towards afternoon kept the city cool, with below-normal temperatures.
