The city recorded its cleanest air day so far this year, on Friday, after the air quality index (AQI) fell to 55, under the ‘satisfactory’ category.

The city recorded its lowest pollution levels since cyclone Ockhi brushed past Mumbai on December 6 last year, when AQI levels had plunged to 43 (good).

The cleanest air day, however, over the past two years and since air monitoring began in Mumbai was recorded on October 12, 2017 when the AQI was 32 (good).

Researchers from the system of air quality weather forecasting and research (SAFAR) said that clean air was expected to continue till Wednesday. SAFAR predicted an AQI of 62 (satisfactory) for Saturday.

“Since parts of central and north India are reeling under high temperatures, coastal areas such as Mumbai are experiencing an increase in wind speed. This is a seasonal phenomenon, and is expected to continue. As a result, pollutants are dispersed fast and there is no time for them to settle close to the surface. Pollution levels are expected to further drop in coming days,” said Gufran Beig, project director, SAFAR.

All 10 locations in Mumbai, where air quality is monitored, recorded either ‘good’ or ‘satisfactory’ air quality.

While BKC had comparatively high pollution levels as compared to other locations, the station still recorded an AQI of 95. The cleanest air in the city was recorded at Malad with an AQI of 22 (good), followed by Andheri and Worli at 24 and 29, both falling under the ‘good’ category. The weather bureau said the sea breeze was setting in at the right time and keeping temperatures close to the normal mark. While Santacruz and Colaba recorded the day temperature at 33 and 32.4 degrees Celsius on Friday, both close to normal, the night temperature was a degree Celsius below normal at Colaba, and 2.3 degree celsius below normal at Santacruz, which recorded 23 degrees Celsius.

A clear sky with day and night temperatures expected at 33 and 23 degrees Celsius has been predicted for Saturday.
