Houston's air quality is heavily influenced by its massive petrochemical industry and heavy vehicle traffic. The city frequently experiences elevated ozone levels, especially during the hot and humid summer months. PM2.5 from industrial sources and vehicle emissions is a year-round concern.
Houston's AQI typically ranges from 40 to 90, with summer ozone episodes frequently reaching the Moderate to Unhealthy for Sensitive Groups range. Industrial areas in the east tend to have worse readings.
Early mornings before sunrise offer the best air quality, as ozone hasn't formed yet and temperatures are lower. Winter months generally have better overall air quality than summer.
