An Air Quality Alert from the National Weather Service Houston/Galveston, updated September 9, 2025. Titled "Ozone Action Day Today," the graphic warns that "Atmospheric conditions are expected to be favorable for producing high levels of ozone pollution in the Houston, Galveston and surrounding areas through this evening." The alert is for "Wednesday, September 10th, 2025."
Three icons with text provide guidance for an Ozone Action Day:
An icon of an ear with a line through it, labeled "Unhealthy for Sensitive Groups."
An icon of a person walking, labeled "Limit Outdoor Activities for Early or Late in the Day."
An icon of a car, labeled "Limit Driving or Carpool."
The right side of the graphic shows a panoramic photo of the downtown Houston skyline on a clear day.
After some mildly cooler, but decidedly less humid days giving us a small taste of fall, we're back to seeing a little more humidity, keeping us solidly in a limbo between late summer and early fall...which is pretty much exactly what we'd expect this time of year!
