The maximum temperature in the city is expected to remain around 30 degrees Celsius and the minimum 22 degrees Celsius. On Thursday, the maximum temperature was 31 degrees Celsius, three degrees below the normal, and the minimum was 22.4 degrees Celsius, a notch above the normal.

According to the Central Pollution Control Board (CPCB), the hourly Air Quality Index (AQI) was 58 at 7am on Friday in the satisfactory category. The average 24-hour AQI was 79 in the same satisfactory category on Thursday.

An AQI between zero and 50 is considered “good”, 51 and 100 “satisfactory”, 101 and 200 “moderate”, 201 and 300 “poor”, 301 and 400 “very poor”, and 401 and 500 “severe”.

The government’s monitoring agency System of Air Quality and Weather Forecasting and Research said dust (size > 2.5 micrometer) contributed ~ 55% to PM10. “For the next 3 days...peak wind speed is likely to be ~ 15-16 km/h causing moderate dispersion and AQI is likely to be within ‘Moderate’ due to expected light rain spells. Moderate temperature (~ 28-33 deg C) and mixing layer height (~ 1.0 km) maintains moderate ventilation.”
