San Antonio rolled into Friday under a blanket of patchy fog and mist that cut down visibility and kept the early-morning temperatures parked in the mid-70s. Forecasters say the fog should lift by about 8 a.m., clearing the way for mostly sunny skies and a hot, summerlike afternoon with a high near 92°F.
Afternoon Heat And Ozone Alert
The Texas Commission on Environmental Quality has called an Ozone Action Day for the San Antonio area for Friday, and the National Weather Service passed the word along, meaning ground-level ozone is expected to climb enough this afternoon that the air could become unhealthy for sensitive groups. Health officials typically urge children, older adults, and people with lung conditions to dial back outdoor exertion during the peak afternoon hours. Look for light southerly winds, sticky humidity, and overnight lows near 72°F, according to NWS Austin/San Antonio.
Weekend Outlook And Next Week
Saturday and Sunday are on track to stay warm and mostly rain-free, with afternoon highs close to 91°F and a chance for patchy fog to sneak in each morning. Rain and thunderstorm chances creep back into the forecast early next week, starting with a slight chance Monday afternoon and increasing to roughly 30–40% by Tuesday and Wednesday as humidity continues to climb. If you have outdoor events lined up for the middle of the week, it is wise to keep those plans a bit flexible.
Practical Tips For Friday
Allow extra time for the morning drive wherever the fog hangs on, and stick with your regular headlights, not high beams, when visibility drops. On an Ozone Action Day, try to postpone nonessential driving, wait until after sunset to refuel, and avoid idling; even small changes help cut down on ozone formation, according to the City of San Antonio. If you have respiratory issues, keep medication handy and steer strenuous workouts or chores indoors during the afternoon.
