According to Lao Dong, the fog phenomenon started from dawn, and after 2pm, the fog still covered the buildings. The area along the Saigon River, Ba Son Bridge or Thu Thiem Peninsula is where the fog appears most densely.
Ms. Tran Thi Thanh (residing in Hanh Thong ward) shared that it has been a long time since she has seen Ho Chi Minh City have such a thick and prolonged fog.
"Looking outside, I only see gray white, trees and high-rise buildings are all covered. It feels like the city is in winter," said Ms. Thanh.
Mr. Trong Huy (residing in Binh Trung ward) said that driving on the road in the morning feels very strange because of the thick fog.
"Many sections of the road ahead are not clear and beautiful, but I am also afraid of affecting my health because I am afraid of fine dust and quite dangerous because of limited visibility," Mr. Huy shared.
According to the Southern Hydrometeorological Station, the cause of the fog is the formation of a convergence zone in the Southern region, combined with high humidity and a drop in temperature after night rain. This condition causes low-level clouds to develop, weak morning sunlight, creating a misty feeling like fog.
Mr. Le Dinh Quyet - Head of Forecasting Department, Southern Hydrometeorological Station added that currently, storm Kalmaegi has entered the eastern sea area of the central East Sea, becoming the 13th storm in the East Sea in 2025. Storm No. 13 does not directly affect the Southern region, but is very strong when entering the East Sea.
These days, the Southern region continues to have rain due to the influence of the tropical convergence zone with an axis through the South - South Central region, connecting with the circulation of storm Kalmaegi. The rainfall may be heavy, even exceeding 100 mm on some days.
The meteorological agency warns that rainy weather, fog during the day combined with fine dust and suspended substances in the air can reduce air quality, affecting health. People are advised to limit outdoor exercise, close windows and wear masks when going out to avoid inhaling fine dust.
