ON TRACK71 days until first freezing night (32°F)Sep 20
Freezing nights in Bend begin around September 20 in a typical year, and as early as September 3 one fall in ten (1991–2020 NOAA normals); pipes come under real risk once lows reach the low 20s. It's a short step from frost to a hard freeze: roughly 14 days on average.

- An early-October first freeze puts Bend ahead of most of the country, so do not wait for the leaves to finish turning.
The reference station for Bend is Bend (1.5 mi, 3,660 ft). First freeze there: 32°F by Sep 20, 28°F by Oct 4, 24°F by Oct 21. That hard freeze has landed anywhere from Sep 18 to Oct 21, a swing of roughly 33 days. Spring's last 32°F freeze clears around Jun 6. Snowfall averages 22 inches a year, first reaching an inch near November.
Bend usually sees its first 32°F night about Sep 20, with the first 28°F hard freeze close behind near Oct 4. Year to year, the first 32°F night has fallen anywhere from Sep 3 to Oct 5 — about 32 days apart. Spring's final freeze lands near Jun 6 and as late as Jun 22, so that is when outdoor water and stored gear can safely come back online. Snowfall averages roughly 22 inches a year — enough that a working snow blower and a clear roof edge earn their keep.
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
Compared with nearby cities, Bend's first-freeze date near Sep 20 sits about a week ahead of Springfield (Oct 23) and about a week ahead of Eugene (Oct 23). Oregon's deadlines span Sep 3 to Nov 11 statewide — one date for all of Oregon would be off by weeks for Bend. Once you know Bend's freeze date, use it to shut down your sprinklers and check your car battery too. Keeping an eye on the rest of the county?

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 Bend?
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 Sep 20.
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.
