When to Prevent Frozen Pipes in Kenner, LA

ON TRACK173 days until first freezing night (32°F)Dec 31

In Kenner, plan for freezing nights from about December 31 onward — one year in ten by December 1 — and treat any low in the low 20s as a pipe-risk night. The early-odds date runs roughly 27 days ahead of the median, so build in that buffer.

NOAA station: New Orleans Intl AP · 0.6 mi away · 4 ft elevation.

Kenner draws its numbers from New Orleans Intl AP, 4 feet up and 0.6 miles away. Its median first-freeze dates are 32°F by Dec 31, 28°F by Jan 7, 24°F by Jan 12. Year to year the 28°F date has ranged from Dec 11 to Feb 6 — about 57 days apart. Spring's last 32°F freeze clears around Jan 30.

The freeze arrives in two steps in Kenner: 32°F around Dec 31, then a hard 28°F near Jan 7. The 32°F date swings from Dec 1 at its earliest to Jan 31 at its latest, near 61 days. The last spring freeze averages Jan 30 and as late as Feb 27, which sets the safe window for reopening outdoor water and de-winterizing gear. Snow barely registers here; the freeze date, around Jan 30, is the one that matters.

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

Compared with nearby cities, Kenner's first-freeze date near Dec 31 sits close to New Orleans (Dec 31) and later than Baton Rouge (Nov 26). Louisiana's deadlines span Nov 1 to Dec 1 statewide — one date for all of Louisiana would be off by weeks for Kenner. Once you know Kenner's freeze date, use it to shut down your sprinklers and check your car battery too.

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 Kenner?
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 Dec 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.
