FORECAST
This weekend (12/20 & 12/21) in San Antonio (Copyright 2025 by KSAT - All rights reserved.)
SATURDAY
We start chilly in the 40s with areas of patchy fog. Then, skies will gradually clear and the high will reach the low-70s. A beautiful day!
SUNDAY
A little more patchy fog for some, but a weak front briefly slides through Sunday morning. This will get rid of the fog and bring slightly cooler highs around 70. This cooler air doesn’t last, as it’ll quickly be replaced by a warm, humid airmass on Monday.
TRAVELING THIS WEEKEND?
There won’t be many issues across Texas this weekend and in fact, most of the country will be travel-friendly. Safe travels!

HOLIDAY WEEK
For late December, we will see an unusually consistent and warm forecast. It’ll feel more like early April, with some mugginess, warm afternoons, and well-above average mornings. Christmas Eve and Christmas Day will see highs in the upper-70s.
