NOAA station: Evansville Museum · 0.5 mi away · 374 ft elevation.

For Evansville, the nearest NOAA station with freeze data is Evansville Museum, 0.5 miles out at 374 feet. Median first-freeze dates there run 32°F by Nov 10, 28°F by Nov 20, 24°F by Dec 1. The 28°F freeze has come as early as Nov 5 and as late as Dec 6, a 31-day spread. Spring's last 32°F freeze clears around Mar 29. Snowfall averages 11 inches a year, first reaching an inch near December.

Expect the first frost near Nov 10 in Evansville and the first hard freeze by about Nov 20. Year to year, the first 32°F night has fallen anywhere from Oct 27 to Nov 25 — about 29 days apart. Spring's final freeze lands near Mar 29 and as late as Apr 11, so that is when outdoor water and stored gear can safely come back online. Snow is light here, near 11 inches a year, so pipe and battery cold usually matters more than plowing.

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, Evansville's first-freeze date near Nov 10 sits later than Owensboro (Nov 2) and later than Bowling Green (Oct 31). Indiana's deadlines span Oct 4 to Oct 31 statewide — one date for all of Indiana would be off by weeks for Evansville. Once you know Evansville'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 Evansville?
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 10.
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.
