The year, day by day
Summer here tops out rather than builds: the warmest normal high is 65°F around August 5, short of 90°F on every date, while 112 dates carry a normal low at or below freezing, the coldest 30°F near February 19.
The freezing stretch
The normal low stays at or below 32°F into March 24, then returns to freezing around December 4, covering 112 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
Where the wet dates fall
The likeliest wet date is October 17, when 78% of years recorded at least a hundredth of an inch. The driest is July 30 at 57%. Summed across the calendar, that is about 245 wet dates a year.
The widest day
April 30 carries the biggest normal gap between afternoon and dawn, 16°F between the normal high and the normal low.

Where Klawock Stands Nationally
This is one of the wettest normals climates ranked: about 89 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 16°F.
Klawock earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Klawock spreads its precipitation across the year
Neither half of the year dominates here: June through August take 16% of the annual total and December through February 28%, with neither reaching the 35% that would mark a distinct wet season. Klawock has no dry season to plan around, though it does carry an unusually narrow 22.2°F seasonal spread.
The gap between the wettest and driest month still matters: October averages 12.3" and June 3.4". The three wettest months together take 37% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
When it rains in Klawock, it arrives in quantity
89.2" of precipitation falls across only about 244 wet days here, averaging 0.36 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 244 a year, 67% of all days
- Average depth per wet day
- 0.36 inches
- Most wet days
- October, about 24
- Fewest wet days
- June, about 18
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Data-derived climate profile
How Klawock's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Klawock, at 7,216 degree days versus 6 for cooling. Unlike a strongly continental record, however, its 22.2°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Klawock's frost-free season lasts about 170 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Klawock's 22.2°F seasonal spread is compact even though precipitation is abundant. August and January mark the typical warm and cold ends of the calendar. The annual average is 45°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
Alongside its heating load, Klawock carries 89.2 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Klawock's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Klawock, not an official NOAA class or a year-ahead forecast.
