HOUSTON, Texas – A crisp fall morning in southeast Texas begins under hazy sunshine, but air quality remains a growing concern as the state rolls into the Columbus Day weekend. The Texas Commission on Environmental Quality has declared an Ozone Action Day for Houston, Galveston, and Brazoria Counties through Saturday evening. The alert signals potentially unhealthy air levels for sensitive groups due to lingering high pressure and light winds.
According to the National Weather Service in Houston/Galveston, stagnant conditions will trap pollutants across the metro area through Saturday. Commuters are urged to share rides or use public transit along I-45 and the Sam Houston Tollway to reduce emissions. The agency also advises residents to limit driving, postpone yard work using gas-powered tools, and conserve energy during peak afternoon hours.
While air quality is the weekend’s primary concern, the weather itself will remain bright and unseasonably warm for mid-October. Sunshine will dominate skies through Columbus Day, with afternoon highs reaching the upper 80s to near 90°F. Light southeast winds will bring a humid touch, but conditions stay ideal for pumpkin patches, outdoor markets, and fall festivals across Harris County.
Forecasters say cooler air could edge into the region late next week, offering a more autumn-like feel just in time for mid-October events. Until then, residents can expect continued sunshine and mild nights — perfect for early holiday decorating or late-evening strolls once ozone levels drop.
