Live U.S. AQI for inland Poway with particulate readings, the next 24-hour peak, and what it means for your day.
Summer inland heat & ozone
Poway's inland valley setting means hotter, stiller summer air than the coast, which lets ozone build up on sunny afternoons.
Best air of the day
Mornings usually have the lowest ozone — the sweet spot for hiking Lake Poway, Iron Mountain or Mt. Woodson before it heats up.
Wildfire smoke season
During Santa Ana wind events in fall, nearby wildfire smoke can push AQI up sharply within hours. Check before outdoor sports or trail plans.
