NOAA station: Westchester Co AP · 3.7 mi away · 379 ft elevation.

Numbers for White Plains come from Westchester Co AP, 3.7 miles away at 379 feet, where the medians fall 32°F by Oct 31, 28°F by Nov 13, 24°F by Nov 25. That hard freeze has landed anywhere from Oct 29 to Nov 29, a swing of roughly 31 days. Spring's last 32°F freeze clears around Apr 12. Snowfall averages 33 inches a year, first reaching an inch near December.

White Plains usually sees its first 32°F night about Oct 31, with the first 28°F hard freeze close behind near Nov 13. That first freezing night has ranged from Oct 15 to Nov 14, roughly a 30-day spread. On the spring side, the last 32°F freeze clears around Apr 12 and as late as Apr 27 — the green light for reopening water and de-winterizing. With around 33 inches of snow annually, plan for a handful of plowable storms each winter.

Your frozen pipes checklist

  1. Disconnect, drain, and store garden hoses, then shut off and drain any interior valves that feed outdoor faucets.
  2. 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
  3. On nights in the low 20s, let a pencil-thin stream of water drip from the faucet farthest from where the line enters.
  4. Open cabinet doors under kitchen and bathroom sinks on outside walls so household heat reaches the plumbing.
  5. 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
  6. Cap outdoor faucets with insulated covers once the hoses are off.
    Helpful gear: Outdoor faucet covers — Recommended pick
  7. Know where your main shutoff is and confirm it turns; a fast shutoff limits water damage if a line lets go.
  8. 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

What this means locally

White Plains freezes about a week ahead of New Rochelle (Nov 16) and about a week ahead of Mount Vernon (Nov 16) — a reminder that even nearby towns differ by days. Statewide, New York prep dates run Sep 28 through Nov 6, which is why White Plains gets its own number rather than a New York-wide average. The same freeze also decides when to shut down your sprinklers and check your car battery.

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 White Plains?
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 Oct 31.
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.
