Houston woke up Monday to a thin, smoky haze that made whole neighborhoods smell like a campfire and turned the skyline into a washed‑out backdrop. Meteorologists say the murky start comes from seasonal agricultural burning in Mexico, with smoke pulled north and puffed up by the muggy spring air.
According to KHOU, satellite imagery and viewer reports point to agricultural fires in Mexico as the source of the haze hanging over the city. Forecasters at KBTX explain that a steady onshore flow, combined with elevated humidity, is swelling fine smoke particles into a visible haze, and most local monitors are showing air quality in the “Moderate” range.
State forecast and satellite confirmation
The Texas Commission on Environmental Quality’s daily forecast notes that light‑density smoke and aerosols from southern and central Mexico, including the Bay of Campeche, can drift north into eastern Texas and push PM2.5 into the lower‑moderate range for Houston today, according to TCEQ. NOAA’s Satellite Services Division has analyzed visible imagery and smoke products that show plumes tracking north over the Gulf in step with the onshore winds meteorologists have described, and the agency’s smoke text product singles out agricultural fire smoke from Mexico and Central America as a contributor. NOAA’s analysis underlines how those distant burns can end up clouding Texas skies.
Who should be careful
The U.S. Environmental Protection Agency warns that fine particulate matter (PM2.5) in smoke can aggravate asthma, heart disease and other respiratory conditions, and that children, older adults and people with lung or heart issues should ease up on outdoor exertion when the Air Quality Index is in the Moderate range or worse. The EPA offers specifics on masks, indoor air cleaning and other ways to protect yourself when smoke rolls in.
