Delhiites on Saturday woke up to a cold morning with shallow fog, while the air quality remained in the 'poor' category. 

At 9 am on Saturday, the average PM2.5 reading was recorded at 70 micrograms per cubic metre while the average PM10 readings at the time were 138 micrograms per cubic metre.

The humidity at 8.30 a.m. was 97 per cent.

"The sky will remain clear throughout the day, with mist or shallow fog in the morning and haze or smog thereafter," an India Meteorological Department (IMD) official said. 

The minimum temperature was recorded at 8.2 degrees Celsius, the season's average, while the maximum temperature was likely to hover around 22 degrees Celsius.

On Friday, the maximum temperature settled at 21.7 degrees Celsius while the minimum temperature was recorded at 8 degrees Celsius, both a notch below the season's average.

Due to meteorological conditions, Monday and Tuesday in Delhi-NCR were the worst breathing days of the month with air quality levels reaching "severe" category, between 401-500. 

The air quality had improved to "poor" on Thursday after overnight rains.

On Friday, as many as nine flights of various airlines were diverted due to low visibility and fog that engulfed the Delhi airport for about two hours in the morning.

Delhi airport is CAT IIIB compliant, where flights can land in visibility as low as 50 metre. However, the diversions on Friday were on account of non-compliant aircraft and flights crew, low-fuel and ATC congestion, the Delhi airport official said.
