Ho Chi Minh City has been blanketed by smog over the past days as unseasonal rain resulted in an increase in humidity, causing pollutants to remain longer in the atmosphere, a weather pundit said.

The smog usually appears in the late morning and lingers until the evening.

Local residents have been unable to see the city’s skyline due to the phenomenon.

According to Le Thi Xuan Lan, former official at the southern hydro-meteorological station, air pollution is a common problem in all big cities.

As unseasonal rain has been dampening Ho Chi Minh City in the past days, humidity in the air has increased, causing dust and pollutants to remain longer in the atmosphere, which resulted in the smog.

“The smog starts becoming thicker in the late morning and afternoon after vehicles and production release a large volume of pollutants into the air,” Lan elaborated.

The weather expert advised people to wear jackets, sunglasses, and face masks when outside to protect their health during this period.
