Mumbai: The lowest weather temperature (15.8 ° C) was recorded in Mumbai on Wednesday morning at the Santa Cruz station of the Indian Meteorological Department (IMD), a senior IMD official said.
While the temperature in Santacruz was 2.2 degrees below normal, the minimum temperature at the Colaba station was 19.6 degrees Celsius, 1.6 degrees above normal. KS Hosalikar, deputy director-general of the western region, IMD, said that this season recorded the lowest temperature at both stations.
“This is the second consecutive day the temperature has dropped. It is a little more-windy today,” he said. The lowest minimum temperature was recorded at 16.4 ° C in December 2019. A year ago, the minimum temperature dropped to 14.4 ° C.
According to IMD, the temperature is likely to remain low for the next few days. Meanwhile, the air quality has deteriorated further as the winter conditions persist.
As opposed to an air quality index (AQI) —a pollutant measuring indicator — a 183 (medium) reading was recorded on Tuesday, an AQI reading of 200 on Wednesday. AQI was calculated by the System of Air Quality Weather Forecasting And Research (SAFAR) as the average of the indices recorded at 10 locations in the city and suburbs. SAFAR categorizes 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.
AQI 341 was recorded in Navi Mumbai, which falls in a very poor category. Bandra Kurla Complex recorded an AQI of 337. SAFAR experts said that poor air quality in the winter season is a regular occurrence and can be attributed to changes in wind direction.
“As the air begins to flow from the land instead of the sea, pollution levels rise because the air coming from the land is more polluted,” a spokesperson said.
