ON TRACK157 days until first 1″ snow (estimated)Dec 15
Have your snow blower ready in Boston by November 24, about three weeks before the first plowable snow, estimated near December 15 from NOAA snowfall normals; fresh fuel, a test start, and spare shear pins now beat a repair-shop line after the first storm. Cold deepens quickly here — only about 12 days separate the first frost from that hard freeze.

- Boston has one of the later first freezes, so watch the live outlook for the odd early cold night.
Boston draws its numbers from Boston Logan Intl AP, 12 feet up and 2.5 miles away. Its median first-freeze dates are 32°F by Nov 9, 28°F by Nov 21, 24°F by Dec 1. The 28°F freeze has come as early as Nov 8 and as late as Dec 5, a 27-day spread. Spring's last 32°F freeze clears around Apr 4. Snowfall averages 49 inches a year, first reaching an inch near December.
The freeze arrives in two steps in Boston: 32°F around Nov 9, then a hard 28°F near Nov 21. That first freezing night has ranged from Oct 29 to Nov 22, roughly a 24-day spread. On the spring side, the last 32°F freeze clears around Apr 4 and as late as Apr 17 — the green light for reopening water and de-winterizing. Snow totals near 49 inches a year mean plowing and ice-dam control share the winter to-do list here.
Your snow blower checklist
- Change the oil and check the level; cold-thickened old oil makes the engine harder to pull over.
- 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
- 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
- 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
- Set the tire pressure to the 15–20 psi range printed on the sidewall so the machine tracks straight.
- Lubricate the auger and chute controls and confirm the chute rotates and tilts freely.
- Do a test start now, well before the first storm, so any repair happens before the shop lines form.
- 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

AriensWhat this means locally
Against its neighbors, Boston (first freeze Dec 15) runs close to Chelsea (Dec 15) and close to Cambridge (Dec 15). Across Massachusetts, local prep deadlines in our data range from Sep 24 to Nov 24, so a statewide rule of thumb would miss Boston by weeks. In Boston, that same cold is your cue to keep your roof edge clear and protect your pipes. Keeping an eye on the rest of the county? The same local math is on our Beverly and Brockton pages.

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 Boston?
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.
How much does a snow blower tune-up cost?
Expect $100–$250 at an independent small-engine shop — single-stage machines at the low end, two-stage models toward the top — and 20–40% more at authorized dealers. Book in September or October: pre-season pricing is lowest, and post-storm emergency service costs 25–50% extra with long waits. DIY materials (oil, plug, stabilizer, shear pins) run about $70.
Is a snow blower safer for your heart than shoveling?
Shoveling is one of the most cardiac-stressful chores there is — American Heart Association research found heart rates exceed 85% of maximum after just two minutes, and an estimated hundred-plus people die during or just after snow removal each year. A snow blower greatly reduces exertion, but pushing one through wet snow is still hard work: take breaks and stop at any chest pressure.
