SmogRank / World / United States / Texas / February 2023

Most polluted cities in Texas, United States, February 2023

19 cities in Texas, United States ranked by their average PM2.5 over the 28 days. Worst: Houston at 12.8 µg/m³, #491 of 1,088 cities in the world. Cleanest: Amarillo at 4.8. A city needs measurements on 70% of the days to be ranked.

OpenAQ's archive, where our readings come from, has almost none for 25 of these 28 days. Cities in the United States and Europe have them from the EPA's and the European Environment Agency's own records of the same monitors; many cities elsewhere are missing from this board, not clean. Why.

Ranked by unhealthy days: the share of each city's measured days with a daily mean over 35.4 µg/m³ (US AQI 101+), Unhealthy for Sensitive Groups or worse on the US EPA's scale. Ties go to the higher average.
