US EPA AQI16:30 UTC+3:30, 3 Nov Main pollutant: PM2.5
Air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
This page uses EPA’s NowCast, which follows the last few hours, as the US government’s AirNow does. On a 24-hour average of particles, as many apps show, it is 115.
Over the next 24 hours the model expects the AQI to range from 54 around 15:30 to 127 around 23:30 (3 Nov).
402nd most polluted of 849 cities worldwide right now, 2nd of 9 in Iran.
What to do today
- Long walk or run outside OK, lighter if very sensitive
- Kids playing outside OK
- Airing the house Open
- Mask outdoors Not needed
Based on the US EPA’s health statement: “Air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.” General guidance, not medical advice.

Where this number comes from
The Copernicus Atmosphere Monitoring Service (CAMS) forecasts air pollution worldwide on a grid (about 11 km over Europe, about 45 km elsewhere). We take the grid value at Shiraz’s coordinates and score it with the US EPA’s method. It is a model, not a measurement: a nearby monitoring station can read quite differently, especially next to busy roads or during fires and dust storms.
