when will it get cold in oklahoma

In most of Oklahoma, it reliably starts feeling cold in late October and especially November, with true winter cold settling in from December through February.

Typical cold timeline

• September: Still hot to warm; 90°F days commonly last into late September in places like Oklahoma City.

• October: Noticeable cooldown, especially late in the month; first real chilly mornings and occasional frosty nights start to show up.

• November: This is when it “gets cold” for many people—average temperatures drop into roughly the 40s–60s range, and freezes become much more common.

Winter months in Oklahoma

• December–February are the coldest months, with typical highs around the 40s–50s and lows in the 20s–30s in much of the state.

• Arctic cold snaps do happen: temperatures can briefly drop near or below 0°F during strong outbreaks, though those events are usually short-lived.

First freeze timing

• In Oklahoma City, the average first freeze of the season is around early November (about November 6 on long‑term climate records).

• Eastern Oklahoma and higher elevations can see freezes in late October, while far southern areas may be a bit later.

Recent and upcoming pattern flavor

• Recent outlooks for Oklahoma winters point to a generally “milder and drier” season overall, but still with notable cold snaps, especially from mid‑December through early February.

• Even in milder winters, brief bitter cold shots and a few snowy or icy periods remain likely, so it can feel like it “suddenly” gets cold multiple times.

  • Plan on cool-to-cold mornings by late October.
