SEASON PASSED188 days until first 1″ snow (estimated)Jan 15

In Beaverton, get the snow blower serviced by December 25, about three weeks before the first plowable snow the normals put near January 15; do the fuel, oil, plug, and a test start early. Year to year the date swings about 73 days, which is why the live outlook beats the calendar.

Numbers for Beaverton come from Nature Park-Beaverton, 1.9 miles away at 185 feet, where the medians fall 32°F by Dec 5, 28°F by Dec 21, 24°F by Dec 30. Year to year the 28°F date has ranged from Nov 24 to Feb 5 — about 73 days apart. Spring's last 32°F freeze clears around Feb 11. Snowfall averages 4 inches a year, first reaching an inch near January.

In Beaverton, freezing nights (32°F) typically begin around Dec 5 and the first hard freeze (28°F) follows near Dec 21. Year to year, the first 32°F night has fallen anywhere from Nov 11 to Jan 12 — about 62 days apart. Spring's final freeze lands near Feb 11 and as late as Mar 5, so that is when outdoor water and stored gear can safely come back online. Snow is light here, near 4 inches a year, so pipe and battery cold usually matters more than plowing.

Your snow blower checklist

  1. Change the oil and check the level; cold-thickened old oil makes the engine harder to pull over.
  2. Drain summer-old fuel and refill with fresh gasoline, then add stabilizer so it stays good through the season.
    Helpful gear: Fuel stabilizer — Recommended pick
  3. Inspect the spark plug and swap it if the tip is dark or worn; a fresh plug is a cheap no-start fix.
    Helpful gear: Replacement spark plug — Recommended pick
  4. Check the shear pins and keep spares on hand — they break on purpose to protect the auger gearbox.
    Helpful gear: Shear pin kit — Recommended pick
  5. Set the tire pressure to the 15–20 psi range printed on the sidewall so the machine tracks straight.
  6. Lubricate the auger and chute controls and confirm the chute rotates and tilts freely.
  7. Do a test start now, well before the first storm, so any repair happens before the shop lines form.
  8. Keep a good shovel by the door for steps and for the day the machine still will not cooperate.
    Helpful gear: Backup snow shovel — Recommended pick

What this means locally

Against its neighbors, Beaverton (first freeze Jan 15) runs close to Tigard (Jan 15) and close to Portland (Jan 15). Across Oregon, local prep deadlines in our data range from Oct 25 to Dec 25, so a statewide rule of thumb would miss Beaverton by weeks. In Beaverton, that same cold is your cue to keep your roof edge clear and protect your pipes.

Frequently asked questions

When should I get my snow blower serviced?
Service the machine about three weeks before the first plowable snow, which here is estimated near Jan 15 from NOAA snowfall normals. Servicing early means fresh fuel, oil, a good plug, and spare shear pins are in place before repair shops fill up after the first storm.
How old can gas be in a snow blower?
Untreated gasoline can start to break down in about 30 days, gumming the carburetor and making the engine hard to start. Use fresh fuel and add stabilizer if it will sit, or run the tank dry at the end of the season. Ethanol-blend fuel is especially prone to trouble in small engines.
Why won't my snow blower start after summer?
The usual culprit is stale fuel that varnished the carburetor over the off-season. A fouled spark plug, old oil, or a clogged fuel line can also be to blame. Draining old gas, fitting a fresh plug, and adding clean, stabilized fuel solves most first-storm no-starts.
What are shear pins and how many spares do I need?
Shear pins are small bolts that connect the auger to its shaft and are designed to break if the auger hits something solid, protecting the gearbox. Keep at least two to four spares and the right size for your model, since a broken pin in mid-storm stops the machine until you replace it.
Electric vs gas snow blower for Beaverton?
Electric and battery machines are quiet, low-maintenance, and fine for lighter, shallower snow and smaller drives. Gas machines handle deep, heavy, wet snow and long driveways better. Match the choice to your typical snowfall and driveway length; heavier-snow areas usually favor gas.
How many inches of snow before using a snow blower?
Most single-stage blowers work best on about two inches or more; below that a shovel or broom is faster. Two-stage machines handle deeper accumulations. Clearing in stages during a big storm, rather than waiting for it to finish, keeps the load on the machine manageable.
