San Antonio, Texas – Texas starts October with an unusual twist: plenty of sunshine, highs in the mid-90s, and an air quality warning in effect for San Antonio and surrounding counties. Residents face lingering heat well above seasonal norms, and sensitive groups are urged to limit outdoor activity as ozone levels spike.
According to the National Weather Service, San Antonio will reach 94°F Tuesday, climbing to 96°F by Thursday before holding near the mid-90s through Friday. The Air Quality Alert remains in place Tuesday, especially for commuters along I-35, where traffic contributes to ozone buildup during peak hours. Calm winds and stagnant conditions may worsen air quality in urban centers.
Drivers should reduce idling in traffic, and families are advised to limit strenuous outdoor activity during the afternoon when ozone levels peak. Cooling centers remain available across Bexar County for those needing relief.
Sunny skies dominate through Saturday, keeping conditions dry but unusually hot for early October. Light winds offer little relief, though evenings will cool into the low 70s, providing comfortable nights.
Heat stress remains possible for outdoor workers and athletes as temperatures linger in the 90s. Hydration and shaded breaks are key.
The pattern shows no major storm systems through early next week, with high pressure anchoring in place over Central Texas. Expect another stretch of dry, sunny days heading into the weekend.
Warnings remain in effect for air quality through Tuesday evening, with updates expected midweek.
