We cannot read conditions right now

We could not reach the wildfire feed for this page, so we cannot tell you what conditions are. That is a problem on our end, not a report of clear air. Check InciWeb and the local agency before you drive out.

Why: Could not read the wildfire feed for this page, so this is not an all-clear

Wind from the N at 11 mph, 70°F — blowing the nearby fire’s smoke across, not at, the park

PM2.5: 3.2 µg/m³

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 U.S. Fish & Wildlife 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.
