Texas – Cool air lingers across San Antonio this New Year’s morning, with breath briefly visible and windshields cool at sunrise. By midday, jackets come off quickly as sunshine takes over and temperatures surge.
Early readings sit near 43 degrees at San Antonio International Airport, with calm winds and clear visibility. The chill fades fast. Afternoon highs climb into the low 70s, making this a comfortable start to 2026 for outdoor plans and holiday travel.
According to the National Weather Service, dry air dominates South-Central Texas today, keeping roads clear and travel smooth along I-35, Loop 410, and Highway 281. No weather-related delays are expected. Drivers should still watch for brief early-morning cool spots on bridges, especially north of downtown.
Tonight stays quiet and mild. Temperatures settle near the mid-50s with light winds and partial cloud cover. Friday turns noticeably warmer. Sunshine pushes highs near 86 degrees, an unusually warm reading for early January. Gusty afternoon breezes may kick up dust in open areas west of the city.
Saturday brings the warmest stretch of the holiday period. Highs approach 79 degrees under sunny skies, perfect for weekend travel, outdoor events, and yard work. Sunday cools slightly but remains pleasant, topping out in the mid-70s with sunshine dominating most of the day.
Meteorologists note this warmth reflects a broader early-2026 pattern across Texas and the Plains. True winter cold stays bottled north for now. Still, clear nights can cool quickly, so lighter layers help early and late.
Looking ahead, mild conditions continue into early next week, keeping energy use low and outdoor plans flexible.
