Houston, Texas – Drivers, joggers, and outdoor workers across Houston could face breathing risks this week as an air quality alert remains in effect while temperatures climb into the low 90s through Wednesday. The combination of ozone buildup and lingering fall heat poses health concerns for sensitive groups, especially children, seniors, and those with asthma. Officials urge residents to limit outdoor activity during the afternoon hours and to use Metro transit or carpooling to cut emissions.
According to the National Weather Service, skies will stay clear and winds light, locking in higher ozone levels and adding to Houston’s air quality strain. The Texas Commission on Environmental Quality warns that exposure during peak afternoon hours may cause coughing, throat irritation, and difficulty breathing for vulnerable groups.
Daytime highs Monday through Wednesday will range from 90 to 92 degrees across Harris County, with little cloud cover to provide relief. North winds near 5 mph will not be strong enough to disperse pollution. Morning lows will sit in the low 70s, keeping the region warm around the clock.
For those traveling on I-45, I-10, and U.S. 59, expect visibility to stay good, but heat on pavement and vehicle emissions may worsen localized air quality during rush hours. Doctors advise keeping inhalers nearby and ensuring air conditioning units recycle indoor air.
Conditions may shift by late week as scattered showers develop Friday into Saturday, bringing modest cooling and a chance for cleaner air. Until then, residents should expect continued hazy skies and high ozone levels through Wednesday night.
