The Santacruz observatory recorded a minimum temperature of 14.8° Celsius on Friday morning, making it the season's lowest so far.

“Northerly winds have pushed down the mercury levels. There will be no large change in the temperature for the next 24 to 48 hours, but a gradual rise in temperature is expected in the coming days,” the official added.
On Wednesday, the city had recorded the lowest temperature for January 2021, at 15.3° Celsius.
“Mumbai Santacruz recorded the lowest minimum temperature of this season on Friday morning from December 2020.

Meanwhile, the air quality index (AQI) continues to remain poor in Mumbai and the adjoining areas:
In Mumbai, the air quality was 'very poor' on Friday, with an overall AQI of 300, according to the System of Air Quality Weather Forecasting and Research (SAFAR).
A spokesperson of SAFAR said: "Due to calm winds in Mumbai and around, polluted continental air coming into the region is not getting dispersed. This condition is leading to poor AQI in Mumbai. Even with the change in wind conditions, the decrease of ventilation will add to local emission with continental pollution, keeping the AQI from poor to very poor for Mumbai in the next two days.”
With AQIs of over 300, places like Malad (332), Andheri (318), Mazgaon (314) and Chembur (309) remained under the 'very poor' category. The Bandra-Kurla Complex (BKC), with an AQI of 286, followed by Colaba (283), Borivli (273) slipped to 'poor', while Bhandup and Worli recorded moderate air quality on Friday with AQIs of 173 and 145 respectively.
SAFAR categorises AQI levels for PM2.5 in the 0-50 range as good; 51-100 as satisfactory; 101-200 as moderate; 201-300 as poor; 301-400 as very poor and above 400 as severe.
