- Late-season freezes are the norm in Winston-Salem, yet an early cold snap can jump the gun by weeks.
- There's a 39-day swing between the early and late freeze dates, meaning the forecast beats the average in any given year.
The reference station for Winston-Salem is Winston Salem Rynlds AP (2.6 mi, 970 ft). First freeze there: 32°F by Nov 9, 28°F by Nov 23, 24°F by Dec 11. That hard freeze has landed anywhere from Nov 5 to Dec 14, a swing of roughly 39 days. Spring's last 32°F freeze clears around Mar 26. Snowfall averages 7 inches a year, first reaching an inch near December.
Expect the first frost near Nov 9 in Winston-Salem and the first hard freeze by about Nov 23. That first freezing night has ranged from Oct 28 to Nov 26, roughly a 29-day spread. On the spring side, the last 32°F freeze clears around Mar 26 and as late as Apr 11 — the green light for reopening water and de-winterizing. Only about 7 inches of snow falls in a typical year, so cold protection outranks snow removal.
Your frozen pipes checklist
- Disconnect, drain, and store garden hoses, then shut off and drain any interior valves that feed outdoor faucets.
- Insulate exposed pipes in the garage, crawl space, and along exterior walls with foam sleeves rated for the pipe size.Helpful gear: Foam pipe insulation sleeves — Recommended pick
- On nights in the low 20s, let a pencil-thin stream of water drip from the faucet farthest from where the line enters.
- Open cabinet doors under kitchen and bathroom sinks on outside walls so household heat reaches the plumbing.
- Add self-regulating heat cable to the runs most likely to freeze, such as a pipe in an unheated garage.Helpful gear: Self-regulating heat cable — Recommended pick
- Cap outdoor faucets with insulated covers once the hoses are off.Helpful gear: Outdoor faucet covers — Recommended pick
- Know where your main shutoff is and confirm it turns; a fast shutoff limits water damage if a line lets go.
- If you travel, keep the thermostat at 55°F or higher and ask someone to check the house during a cold snap.Helpful gear: Wi-Fi water leak sensor — Recommended pick

American Red CrossWhat this means locally
Against its neighbors, Winston-Salem (first freeze Nov 9) runs later than High Point (Nov 5) and later than Greensboro (Nov 4). Across North Carolina, local prep deadlines in our data range from Oct 17 to Nov 5, so a statewide rule of thumb would miss Winston-Salem by weeks. In Winston-Salem, that same cold is your cue to shut down your sprinklers and check your car battery. Keeping an eye on the rest of the county? The same local math is on our Wilson and Apex pages.

Frequently asked questions
At what temperature do pipes freeze?
Pipes generally come under risk when the temperature outside falls to about 20°F, the threshold many guides use for taking action. Pipes in unheated or exterior-wall spaces freeze sooner than well-insulated interior runs. Wind and poor insulation lower the effective temperature, so a windy night in the mid-20s can be as risky as a still night in the low 20s.
Should I drip my faucets tonight in Winston-Salem?
If the overnight low is forecast at or below about 20°F, letting a thin stream run from the faucet farthest along the line is a low-cost precaution. Moving water is slower to freeze and relieves pressure. Check tonight's low against the live outlook above; freezing nights here typically begin around Nov 9.
How long does it take for pipes to freeze?
There is no fixed clock; it depends on pipe location, insulation, and how far below freezing the air drops. An exposed pipe in a windy, unheated space can freeze in a matter of hours during a hard cold snap, while a protected interior pipe may never reach freezing. The colder and windier it is, the faster it happens.
Which pipes freeze first?
The most exposed pipes freeze first: outdoor hose bibs, and lines in unheated garages, crawl spaces, attics, and along exterior walls. Pipes under sinks on outside walls are common trouble spots. That is why disconnecting hoses and opening cabinet doors on cold nights are two of the highest-value steps.
Does homeowners insurance cover burst pipes?
Sudden, accidental water damage from a frozen pipe is often covered, but insurers may deny a claim if the home was left unheated or the damage is judged to be from neglect. Coverage varies by policy. Keeping the heat on and taking reasonable precautions helps protect both your home and your claim.
What temperature should I keep my house if I'm away?
A common recommendation is to keep the thermostat no lower than 55°F while you are away so interior walls stay warm enough to protect the plumbing. Leaving cabinet doors open and having someone check the house during a cold snap adds a margin of safety, especially for pipes on exterior walls.
