Gurugram recorded a most temperature of 26.8°C and a minimal of 11.1°C. Low wind pace contributed to pollutant buildup. “As a result of very gradual wind pace, pollution have accrued and are usually not getting dispersed… no western disturbance or rainfall is anticipated for the following week,” mentioned Mahesh Palawat of Skymet Climate.
