Check first

Check conditions before you go

Open, but check conditions first. A fire is burning about 3 miles away. Easy outings are fine; save the big push for a clearer day.

Why: 3 fires within 50 mi

Wind from the SW at 16 mph, 56°F — blowing the nearby fire’s smoke away from you

PM2.5: 15.5 µg/m³ from the nearest monitor

Conditions change fast and this data can be delayed or estimated. Treat this as guidance, not a guarantee, and check official sources and agency and AirNow alerts before you go.

About this data

AQI from EPA AirNow monitors, and where none is close, the nearest EPA-corrected PurpleAir community sensor (labeled as an estimate). Refreshed through the day. Managed by National Park Service. Wind from Open-Meteo. Fire data from NIFC WFIGS. Smoke analysis from NOAA HMS. Boundaries from USGS PAD-US 4.0. Where no sensor is anywhere near, we say so rather than guess.
