SAN ANTONIO – Our streak of record-challenging warmth continued into the first day of 2022, but a cold front Saturday night brought the first freeze of the season to the Alamo City.

With clear skies and calm winds Sunday night, temperatures will quickly drop, and we’ll see a hard freeze Monday morning.

Here’s what you need to know:


Monday morning temps in San Antonio will be in the low-20s.

Folks in the Hill Country will be below freezing for more than 12 hours, while those around SA and Del Rio should expect to be below freezing for 8-12 hours. That’s enough to cause delicate plants to die, so keep them inside or cover them up! Make sure your pets have a warm place to stay tonight, too.

As for pipes...not really worried about them bursting in San Antonio, but those in the Hill Country should insulate any exposed pipes just in case! After the cold morning, it’ll warm into the 50s with plenty of sunshine. Winds will be light and variable.


Thereafter, temperatures will briefly warm into the 60s and 70s ahead of our next cold front, which is expected to arrive on Thursday.
