The AQI was recorded at 346 on Saturday, at 366 on Friday and at 302 the previous day. SAFAR said the air quality in Delhi worsened mainly because the extremely calm local surface winds, which were prevailing since the last few days, are likely to increase slightly and may further pick-up by October 26.  "Slow improvement in the current condition is expected by October 26, leading to a middle range of 'very poor'," it said.
