Boat column rule: in the water at a 65°F high and 45°F low or warmer; launch or haul-out from a 52°F high; laid up below.
By that rule a boat at Anchorage has 1 month in the water (July to July), 4 of launch or haul-out and 7 laid up. By that rule a boat at Fairbanks has 3 months in the water (June to August), 2 of launch or haul-out and 7 laid up.
Alaska is severe-freeze country for a boat: Fairbanks averages -17.2°F on January nights and about 113.8 nights a year at or below 0°F, so full winterization is mandatory and heated space is worth pricing.
36 live listings in 11 cities; by listed type: 28 indoor, 19 covered and 33 outdoor (types overlap). No Alaska boat storage listing publishes a rate on StowHelp.

NOAA's 1991-2020 median first 32°F night is October 1 at Anchorage and September 13 at Fairbanks; winterize by August 30, two weeks ahead of the earlier date. By our boat rule Anchorage stays in the water through July and Fairbanks through August, then 4 months of launch or haul-out follow at Anchorage. 28 Alaska listings offer indoor or climate-controlled space.
7 at Anchorage (August to June) and 7 at Fairbanks (September to May), plus 4 and 2 months of launch or haul-out. Those laid up months hold 77.2 of the 77.9 inches of snow Anchorage averages a year (99%), which is the load on a cover or carport roof. At Anchorage a boat is in the water from July to July (1 month), against 3 at Fairbanks.
Of 36 live Alaska listings, 28 list indoor space and 0 climate-controlled units, against 33 outdoor and 19 covered. By city: Anchorage (17 listed, 14 indoor), Eagle River (4 listed, 4 indoor), Soldotna (4 listed, 4 indoor) and Palmer (3 listed, 3 indoor). Most indoor listings: Anchorage (14), Eagle River (4) and Soldotna (4). Ask whether indoor means heated; listings span 11 cities in all.
At Fairbanks, 7 months average a low at or below 32°F, all of them laid up months by our boat rule. Fairbanks logs 221.7 nights at or below 32°F and 113.8 at or below 0°F a year; January, the coldest month, averages -17.2°F and is laid up for a boat.
After the last frost. The median last 32°F night is May 5 at Anchorage and May 13 at Fairbanks; the last 28°F hard freeze comes around April 22 and May 4. Our rule makes July the first month in the water at Anchorage and June at Fairbanks. That month Anchorage averages a 52.9°F low and a 66.2°F high. Reverse each winterization step first.
