Currently the air is at 127 AQI for PM2.5 in District 4 of Saigon. Looking at the picture below, you can tell it is much higher in Phu My Hung (District 8). As usual, when the air is bad, you cannot see the Phu My Bridge which is around 5 km away. It will be another bad air day in Saigon.
Wear your masks.
