At 4.2 degrees Celsius temperature on Tuesday morning, Delhi matched the record of its lowest minimum temperature for this season, the weather department said. The city had witnessed a similar dip in temperature on Saturday.

But with the wind speed picking up, visibility was at a decent 400 metres at 8.30am, an official with the weather department said.

“Over this week, there is unlikely to be dense fog. There will be shallow or moderate fog in the morning hours, but the wind will dissipate it during the day,” said the weatherman.

However, railway commuters leaving from Delhi were still affected as 26 trains departing from the city’s stations were cancelled and 23 rescheduled until 6.30am on Tuesday, a list issued by the railways said. According to news agency, ANI, two arriving and six departing flights were delayed due to fog on Tuesday.

The air pollution also turned worse on Tuesday and the air quality index (AQI) — a measure of pollutants in the air — was recorded at 322 that classifies as ‘very poor’, said the Central Pollution Control Board (CPCB). This reading was made at 8.30am. On Monday, the AQI was 297 which falls in ‘poor’ category.

The AQI is calculated on a scale of 0-500. An AQI between 0-0 is considered good, 51-100 satisfactory, 101-200 moderate, 201-300 poor, 301-400 very poor and 401-500 severe.

The worsening air pollution can be gauged from the reading of Shadipur station. On Monday, it had recorded the best air with a moderate AQI of 143, but on Tuesday it spiked to very poor levels with an AQI of 346.

On Tuesday, the minimum and maximum temperature stood at 4.2 and 21.7 degrees Celsius, the weather official said. That put the minimum temperature more than two degrees below the normal at this time of the season.

“The temperature on Wednesday will oscillate between 5 degree and 21 degree Celsius. The morning hours will witness shallow or moderate fog but it will be clear sky in the day,” the weather official said.
