It usually starts to feel genuinely cold in Texas from late November through January, but it depends a lot on which part of Texas you mean and what you call “cold.”

Big picture: Texas “cold”

  • The astronomical start of winter is around December 21, but many parts of Texas start cooling down in November, with the coldest stretch typically in January.
  • Because Texas is huge, there can be roughly a 20-degree difference between the north and south of the state on a typical winter day.

By region

  • North Texas (Dallas, Amarillo, Lubbock)
    • Noticeably cooler days often show up in October–November.
* Winter highs usually run in the 40s–50s, with nights at or below freezing and occasional snow or ice.
  • Central Texas (Austin, San Antonio, Hill Country)
    • Truly cool fronts start rolling in from October, but many days stay mild into December.
* Typical January days are in the 60s with nights in the 40s, and brief cold snaps can drop temps near or below freezing.
  • South / Southeast Texas (Houston, Corpus Christi, Rio Grande Valley)
    • “Cold” is late December through February, and even then days often stay in the 60s.
* Freezing nights are rare; in many winters they never happen or only occur briefly.
  • West Texas (El Paso, Midland/Odessa)
    • December–February brings daytime highs mainly in the 50s–60s and colder, often windy nights.
* Snow is less common than in the Panhandle, but strong cold fronts can still make it feel sharply colder.

What people in Texas say it feels like

  • Locals around Dallas often describe “real winter” as late January into February, with lows in the 30s and 40s and recurring cold snaps and ice rather than constant deep cold.
  • Many residents think of “winter” more like extended fall: a chilly front for a few days, then back to 60s or even 70s before the next front.

If you’re wondering about this year

Forecasts shift week by week, but the pattern most years is:

  1. First noticeable cool fronts: September–October (it stops being brutally hot, especially in North and Central Texas).
  1. Consistently cool to cold: late November through February, coldest overall in January.
  1. Occasional extreme Arctic blasts, like the February 2021 event, can make it much colder than normal for a few days but are not every year events.

If you share your nearest city and what “cold” means for you (50s? 30s? freezing?), a more tailored temperature window can be outlined for your area.
