SAN ANTONIO – December will begin fittingly with temps tumbling below freezing. Here’s what you need to know:

  • With clear skies, light winds, and bone-dry air in place Monday night, temperatures will drop like a rock
  • By early Tuesday morning, temperatures will be near 30° in San Antonio - two degrees below the freezing mark
  • It’s expected to be even colder in the Hill Country, where temperatures could dip into the mid-to upper 20s for several hours early Tuesday, resulting in a hard freeze
Temps are expected to dip below freezing for most of the KSAT-12 viewing area by sunrise Tuesday morning (Copyright 2020 by KSAT - All rights reserved.)

How to Prepare for a Freeze

When preparing for a freeze, there are a few things to remember. Be sure to bring any small, potted plants inside and cover larger ones with a sheet. Prepare a warm shelter for your outdoor pets - or better yet, bring them inside! Finally, if you live outside of the city center and have exposed pipes, make sure to cover them. San Antonio is only expecting a light freeze Tuesday morning, so if you live in the Alamo City, wrapping plumbing pipes is not necessary.

First Freeze Climatology

This first freeze will be right on schedule, at least according to climate norms. Central Bexar County, including the San Antonio metro, typically sees its first freeze in late November.
