ON TRACK157 days until first 1″ snow (estimated)Dec 15

NOAA station: Boston Logan Intl AP · 6.3 mi away · 12 ft elevation · est. first 1" snow: Dec 15.

The reference station for Medford is Boston Logan Intl AP (6.3 mi, 12 ft). First freeze there: 32°F by Nov 9, 28°F by Nov 21, 24°F by Dec 1. Year to year the 28°F date has ranged from Nov 8 to Dec 5 — about 27 days apart. Spring's last 32°F freeze clears around Apr 4. Snowfall averages 49 inches a year, first reaching an inch near December.

Expect the first frost near Nov 9 in Medford and the first hard freeze by about Nov 21. Year to year, the first 32°F night has fallen anywhere from Oct 29 to Nov 22 — about 24 days apart. Spring's final freeze lands near Apr 4 and as late as Apr 17, so that is when outdoor water and stored gear can safely come back online. With about 49 inches of snow a year, roof, snow-blower, and ice-dam prep all belong on the same calendar.

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

Medford freezes close to Malden (Dec 15) and close to Somerville (Dec 15) — a reminder that even nearby towns differ by days. Statewide, Massachusetts prep dates run Sep 24 through Nov 24, which is why Medford gets its own number rather than a Massachusetts-wide average. The same freeze also decides when 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 Dec 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 Medford?
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.
