When to Store Your Motorcycle in Auburn, WA

ON TRACK122 days until first 32°F freezeNov 10

Layup time in Auburn tracks the first 32°F freeze, which averages November 10: stabilize the fuel, change the oil, and keep the battery on a tender through the cold. Riding tends to open again after the last freeze near March 20. Year to year the date swings about 44 days, which is why the live outlook beats the calendar.

NOAA station: Kent · 7.6 mi away · 30 ft elevation.

The reference station for Auburn is Kent (7.6 mi, 30 ft). First freeze there: 32°F by Nov 10, 28°F by Nov 24, 24°F by Dec 8. The 28°F freeze has come as early as Nov 6 and as late as Dec 20, a 44-day spread. Spring's last 32°F freeze clears around Mar 20. Snowfall averages 6 inches a year, first reaching an inch near December.

In Auburn, freezing nights (32°F) typically begin around Nov 10 and the first hard freeze (28°F) follows near Nov 24. Year to year, the first 32°F night has fallen anywhere from Oct 26 to Nov 26 — about 31 days apart. Spring's final freeze lands near Mar 20 and as late as Apr 8, so that is when outdoor water and stored gear can safely come back online. Snow is light here, near 6 inches a year, so pipe and battery cold usually matters more than plowing.

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

Against its neighbors, Auburn (first freeze Nov 10) runs about a week ahead of Federal Way (Nov 14) and close to Kent (Nov 10). Across Washington, local prep deadlines in our data range from Oct 4 to Nov 23, so a statewide rule of thumb would miss Auburn by weeks. In Auburn, that same cold is your cue to test your car battery and winterize a boat.

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 Auburn?
Riding season here tends to wind down as freezing nights arrive near Nov 10, 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 Auburn the last freeze averages near Mar 20, a reasonable target for shaking off storage. Clean and lube the chain, and take an easy first ride to re-familiarize yourself.
