It’s been 328 days since San Antonio temperatures last dipped to 32 degrees or colder, with the most recent freeze day occurring on Feb. 22, 2025. That streak could finally come to an end this weekend, courtesy of a strong cold front sweeping through Texas on Friday.
The coldest air won’t arrive until late Saturday night, but it could bring a brief freeze to the San Antonio metro area. To the north, including much of the Hill Country, a likely hard freeze could affect indoor and outdoor plumbing. Here’s an overview of what you can expect this weekend.
Friday’s forecast
Another chilly start is expected across South-Central Texas on Friday, similar to what we’ve seen over the past few days. Temperatures are expected to sit in the lower 40s in San Antonio between 4 and 8 a.m., rising to 50 degrees by 9 a.m.
Before the cold front arrives, you can expect warm weather through the middle of the day. San Antonio temps will reach 60 degrees by 11 a.m., likely touching the 70-degree mark by around 1 p.m. Afternoon temps are expected to peak at 72 degrees in San Antonio, just before the cold front plunges through the city by 3 p.m.
Upon the front’s arrival, temperatures will likely drop into the 50s by 6 p.m. Winds will turn gusty, coming in from the north at 15 to 20 mph. Temps will drop into the 40s after midnight, eventually sinking to the lower 40s early Saturday.
When will temps fall below freezing?
With northeast winds continuing to blow in at 10 to 15 mph, temperatures will stay below average all day Saturday. Temps will top out only in the mid-50s under partly cloudy skies. An isolated shower remains possible, especially south of San Antonio, but rain chances will be quite low…
