Skies were beginning to clear across downtown San Antonio Tuesday afternoon. Bright sunshine is expected Wednesday, as a front brings dry air.
Shown are the potential low temperatures across Texas late Saturday and into early Sunday. Subfreezing predawn temps are likely for many.

Overview

  • San Antonio has yet to hit 32°F this winter, placing 2025–26 among the latest first-freeze dates on record at the airport.
  • A stronger front arriving Friday night will drop temperatures into the 30s Saturday night, with a brief, light freeze possible in the city but most models keeping lows just above 32°F.
  • Hill Country locations are expected to fall well below freezing late Saturday into Sunday, around 25–28°F from Kerrville to Fredericksburg, after multiple freezes already this season.
  • A midweek front delivered 35–45 mph wind gusts and elevated fire danger, with metro lows in the upper 30s and light freezes limited to higher terrain.
  • Since Dec. 1, San Antonio’s average low has been 49.3°F—about 7°F above normal—while NOAA’s late‑January outlook favors near‑ to above‑average temperatures if the weekend fails to produce a freeze.
