Living Well in Good Air
AQI 0–50 means air quality poses little to no risk for the general population, with comfortable conditions for outdoor activity.
Use these days to plan outdoor projects, exercise, and time-sensitive fieldwork. AQI can change quickly under wildfire smoke — check the Detection Map for active fires upwind of your location and the Weather page for wind direction. Good air days are the baseline; everything else is relative.
