The city witnessed a slight increase in the maximum and minimum temperatures as the year 2020 drew to an end on Thursday, December 31.

Meanwhile, according to the System of Air Quality Weather Forecasting And Research (SAFAR), on the first day of the Year 2021, the city recorded the highest January 1 pollution levels in four years. However, it was still lower than that of Thursday, December 31. Mumbai's overall air quality index of 307 was in the very poor category on New Years’ eve, according to the SAFAR.

Besides, it was also observed that the air quality in and around Mumbai deteriorated from ‘poor’ to ‘very poor’ for the first time in 2020 on New Year's Eve, December 31. Experts attributed the very poor quality of air to the inflow of air from the land (continental air) instead of that from the sea.

Apart from that, 2020's second-worst AQI was recorded on March 17 at 272. According to the reports, on January 1, among the 10 locations monitored by SAFAR, four-Malad, Mazgaon, Chembur and Bandra-Kurla Complex- were the most polluted with an AQI over 300. Borivli was the least polluted with an AQI of 86.

Moreover, in spite of the state's standard operating procedure that called for citizens to not burst firecrackers on New Year's Eve, crackers were burst in most parts of the city and even old man effigies were being burnt.

SAFAR had predicted an AQI of 293 for January 1. Even as temperatures rose on Friday morning, January 1, the AQI dipped only marginally to 303 but deteriorated to 307 by evening. This is considered to be in a very poor category triggering a health alert for everyone. Though, the worst AQI on January 1 since SAFAR began monitoring pollution levels, in 2015, was recorded in 2016 at 323. 

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.

As on January 2, IMD’s Mumbai regional representative at Santacruz and Colaba recorded a minimum temperature of 22.7 and 23 degree Celsius, respectively. Similarly, the maximum temperature of 33.6 and 31.6 degrees at the two weather stations was higher than normal by 2.6 and 2.7 degrees. Besides, the department also stated that the sky is likely to be partly cloudy for the next 24 hours. Also, SAFAR had predicted the AQI to be 305 on Saturday, January 2.
