# Air Quality

**US AQI: 34 — Good** (main pollutant: ozone)

_Measured by the closest reporting Texas Commission on Environmental Quality monitor for each pollutant (per AirNow) in the Houston-Galveston-Brazoria, TX area — the nearest official monitors to Crosby, which has none of its own (PM2.5 — Baytown; ozone — Baytown Garth; PM10 — Clinton). A real reading for the area, not a Crosby-pinpoint value. Observed 2026-10-18 18:00 CDT._

## By pollutant

- ozone: 34 (Good) — Baytown Garth
- PM2.5: 31 (Good) — Baytown
- PM10: 12 (Good) — Clinton

## Nearby ozone monitor

- Channelview C15 (ozone): 38 (Good) — updated Oct 18, 5:00 PM CDT
  Nearest dedicated ozone monitor (~8.5 mi); a cross-check so a locally elevated reading isn't hidden by the closest-per-pollutant headline.

## What this means

Air quality is good — no precautions needed.
