ON TRACK157 days until first 1″ snow (estimated)Dec 15
The first plowable snow in Annapolis is estimated near December 15 (NOAA snowfall normals), so service the machine by November 24 — roughly three weeks ahead — with fresh, stabilized fuel and a test start. The early-to-late range spans roughly 40 days, so treat the median as a midpoint, not a promise.

- Annapolis has one of the later first freezes, so watch the live outlook for the odd early cold night.
- With about 40 days separating the early and late dates, watch the live outlook rather than banking on the median.
Numbers for Annapolis come from Annapolis Police Brks, 1.3 miles away at 25 feet, where the medians fall 32°F by Nov 13, 28°F by Nov 28, 24°F by Dec 13. The 28°F freeze has come as early as Nov 9 and as late as Dec 19, a 40-day spread. Spring's last 32°F freeze clears around Mar 27. Snowfall averages 19 inches a year, first reaching an inch near December.
Annapolis usually sees its first 32°F night about Nov 13, with the first 28°F hard freeze close behind near Nov 28. The 32°F date swings from Nov 1 at its earliest to Dec 1 at its latest, near 30 days. The last spring freeze averages Mar 27 and as late as Apr 9, which sets the safe window for reopening outdoor water and de-winterizing gear. About 19 inches of snow a year is enough to justify servicing the snow blower and watching the eaves.
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
Annapolis freezes close to Bowie (Dec 15) and close to Baltimore (Dec 15) — a reminder that even nearby towns differ by days. Statewide, Maryland prep dates run Nov 24 through Dec 25, which is why Annapolis gets its own number rather than a Maryland-wide average. The same freeze also decides when 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 Rockville page.

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 Annapolis?
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.
