From early morning, fog and drizzle appeared over a large area in Hanoi, limiting visibility.

High-rise buildings along Tran Phu (Ha Dong district) and Nguyen Trai (Thanh Xuan district) were covered by drizzle and fog so their roofs were invisible.

Fog limited visibility. On inner-city roads, until 9 am many vehicles still had to turn on their lights.

The air was thick with fog, rain and dust. According to data from Airvisual website, the average AQI index in Hanoi in the morning was 169 units, which is considered harmful to human health.

The cold air had weakened, while the density of pollutants from traffic activities and construction works did not decrease. Therefore, pollutants could not spread upward. At the same time, the high humidity and increasing heat in Hanoi caused smog, leading to more serious air pollution.
