When to Store Your Motorcycle in Juneau, AK
As freezing nights reach Juneau around October 22, riding gets impractical and it's time to store the motorcycle properly instead of idling it now and then. Riding tends to open again after the last freeze near April 20. The early-odds date runs roughly 18 days ahead of the median, so build in that buffer.

Juneau draws its numbers from Juneau Dwtn, 50 feet up and 0.4 miles away. Its median first-freeze dates are 32°F by Oct 22, 28°F by Nov 8, 24°F by Nov 22. Year to year the 28°F date has ranged from Oct 21 to Nov 26 — about 36 days apart. Spring's last 32°F freeze clears around Apr 20. Snowfall averages 88 inches a year, first reaching an inch near November.
The freeze arrives in two steps in Juneau: 32°F around Oct 22, then a hard 28°F near Nov 8. The 32°F date swings from Oct 5 at its earliest to Nov 7 at its latest, near 33 days. The last spring freeze averages Apr 20 and as late as May 5, which sets the safe window for reopening outdoor water and de-winterizing gear. Roughly 88 inches of snow fall in an average year, so a clear roof edge and a running snow blower matter as much as the freeze itself.
Your motorcycle checklist
- 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
- Change the oil and filter before storage so acids in used oil do not sit on internal parts all winter.
- 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
- 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
- Lube the chain and wipe down bare metal with a light protectant to fend off corrosion.
- Plug the exhaust and airbox loosely so mice cannot nest, and set traps nearby as a backup.
- Cover the bike with a breathable cover indoors so moisture does not get trapped against the paint.Helpful gear: Breathable motorcycle cover — Recommended pick
- In spring, remove the plugs, check tire pressure and brakes, and reconnect the battery before the first ride.
