The year, day by day
Summer here tops out rather than builds: the warmest normal high is 63°F around July 31, short of 90°F on every date, while 180 dates carry a normal low at or below freezing, the coldest 20°F near January 9.
The freezing stretch
The normal low stays at or below 32°F into April 19, then returns to freezing around October 23, covering 180 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 September 26, when 63% of years recorded at least a hundredth of an inch. The driest is June 2 at 36%. Summed across the calendar, that is about 179 wet dates a year.
The widest day
June 5 carries the biggest normal gap between afternoon and dawn, 15°F between the normal high and the normal low.

Where Seldovia Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 15°F.
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 180 nights a year, more than most ranked stations.
Seldovia earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Seldovia's wet season runs through the cold months
December, January and February carry 35% of the year's precipitation here, while June through August contribute 13%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows an unusually narrow 29.6°F seasonal spread.
- Wettest month
- December, 6.7"
- Driest month
- June, 1.1"
- Wettest three months
- December, November, October (40% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.
How Seldovia's precipitation splits across the calendar
About 179 days a year record measurable precipitation here, carrying 40.4" between them, or roughly 0.23 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.

Data-derived climate profile
How Seldovia's climate pattern fits together
heating led · moderate · low swing
Heating is the larger measured load in Seldovia, at 9,288 degree days versus 1 for cooling. Unlike a strongly continental record, however, its 29.6°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Only about 144 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
Temperature varies within a narrow 29.6°F band across the normal year. July and January mark the typical warm and cold ends of the calendar. The annual average is 40°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
Seldovia's 40.4 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Seldovia'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 Seldovia, not an official NOAA class or a year-ahead forecast.
