NOAA station: Newark · 1.1 mi away · 10 ft elevation.

Numbers for Newark come from Newark, 1.1 miles away at 10 feet, where the medians fall 32°F by Dec 27. Spring's last 32°F freeze clears around Jan 1.

The first frost in Newark lands near Dec 27, and temperatures seldom push down to a hard 28°F. The 32°F date swings from Dec 9 at its earliest to Jan 14 at its latest, near 36 days. The last spring freeze averages Jan 1 and as late as Jan 22, which sets the safe window for reopening outdoor water and de-winterizing gear. Snow barely registers here; the freeze date, around Jan 1, is the one that matters.

Your motorcycle checklist

  1. Fill the tank and add fuel stabilizer, then ride or idle a few minutes so treated fuel reaches the injectors or carbs.
    Helpful gear: Fuel stabilizer — Recommended pick
  2. Change the oil and filter before storage so acids in used oil do not sit on internal parts all winter.
  3. Put the battery on a tender for the whole layup rather than starting the bike for a few minutes now and then.
    Helpful gear: Battery tender — Recommended pick
  4. Set tire pressure to spec and, if you can, lift the wheels with stands so the tires do not flat-spot.
    Helpful gear: Front paddock stand — Recommended pick
  5. Lube the chain and wipe down bare metal with a light protectant to fend off corrosion.
  6. Plug the exhaust and airbox loosely so mice cannot nest, and set traps nearby as a backup.
  7. Cover the bike with a breathable cover indoors so moisture does not get trapped against the paint.
    Helpful gear: Breathable motorcycle cover — Recommended pick
  8. In spring, remove the plugs, check tire pressure and brakes, and reconnect the battery before the first ride.

What this means locally

Newark freezes later than Fremont (Dec 22) and later than Union City (Dec 22) — a reminder that even nearby towns differ by days. Statewide, California prep dates run Jan 1 through Dec 31, which is why Newark gets its own number rather than a California-wide average.

Frequently asked questions

Should I start my motorcycle during winter storage?
It is better not to. Starting the bike for a few minutes does not fully warm the oil or charge the battery, and it leaves moisture and acids inside the engine and exhaust. A battery tender keeps the battery healthy without running the engine, which is the approach most enthusiasts and manuals favor.
Do I store a motorcycle with a full or empty tank?
Store it with a full tank and fuel stabilizer added. A full tank leaves less room for the condensation that causes rust inside the tank, and stabilizer keeps the fuel from breaking down over months of storage. Ride or idle briefly after adding stabilizer so it reaches the fuel system.
How do I keep mice out of my motorcycle?
Loosely plug the exhaust outlets and the airbox intake so mice cannot get inside and nest, and remove the plugs before spring. Set traps or deterrents around the storage area, and avoid leaving food or cardboard nearby. Check periodically through the winter for signs of activity.
Battery tender vs trickle charger?
A modern battery tender, or smart charger, monitors the battery and switches to a maintenance charge when full, so it is safe to leave connected all winter. A basic trickle charger keeps pushing current and can overcharge a battery over time. For long storage, use a tender.
When does riding season end in Newark?
Riding season here tends to wind down as freezing nights arrive near Dec 27, and reliably cold, dark evenings make regular riding less practical. Watch the live outlook above; a run of sub-45°F nights is a good signal to fuel-stabilize and put the bike on the tender.
How do I prep a motorcycle for spring?
Reconnect the charged battery, check tire pressure and tread, test the brakes, and look for leaks before the first ride. In Newark the last freeze averages near Jan 1, a reasonable target for shaking off storage. Clean and lube the chain, and take an easy first ride to re-familiarize yourself.
