From early morning, many roads, alleys, and buildings in Ho Chi Minh City were engulfed in dense fog, and vehicles running on the road had to turn on their lights.

In the early morning of July 22, throughout the roads and buildings from the center to the outskirts of Ho Chi Minh City, fog covered the scene like Da Lat. In Thu Duc City, the row of houses was covered with fog at 6 o’clock.

Fog covers the apartment blocks in District 8, standing a few tens of meters away but can’t see clearly. “Fog like this is actually not rare in Saigon, but it’s very dense like today. It’s cool, it’s natural to see life slow down,” said Mr. Nghia, who lives in District 8.

Mist covered the small alleys.

At the intersection of Vo Van Kiet – An Duong Vuong (District 8) at 6 o’clock, thick fog obscured the signboard on the feather gate, and the red light limited the visibility of pedestrians. All vehicles must have their lights on.

Binh Loi Bridge is blurred in the fog.

At 7 a.m., when the sun rises, the dew gradually dissipates. It is more convenient for people to run across Thu Thiem 2 bridge, no longer having limited visibility.

The fog and cool weather make many people participate in outdoor activities excited. “It’s very foggy today, it’s strange, usually in Ho Chi Minh City until the end of the year, this phenomenon occurs. I feel less tired when I jog,” said Mr. Hoang.

Ms. Lan happily feeds the pigeons on Nguyen Hue pedestrian street, district 1. “This morning there was fog all over the street that I thought was in Da Lat”, she said.

Weather expert Le Thi Xuan Lan said that thick fog set in plains like Ho Chi Minh City this morning is very rare, appearing only a few times a year. The reason is due to heavy rain lasting for many days, especially yesterday it rained from noon to night, making the air humidity up to 100% and the level of air pollution high.

“Smoke and dust from motorbikes, cars, exhaust gases cause water vapor particles to cling to form fog, plus light winds cause the fog to hover at a low level,” said Ms. Lan. In addition, the temperature this morning dropped to low, some places below 24 degrees Celsius, causing strong condensation.
