The year, day by day
Summer here tops out rather than builds: the warmest normal high is 64°F around July 25, short of 90°F on every date, while 181 dates carry a normal low at or below freezing, the coldest 18°F near January 10.
The freezing stretch
The normal low stays at or below 32°F into April 17, then returns to freezing around October 20, covering 181 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 19, when 55% of years recorded at least a hundredth of an inch. The driest is May 15 at 31%. Summed across the calendar, that is about 157 wet dates a year.
The widest day
May 15 carries the biggest normal gap between afternoon and dawn, 16°F between the normal high and the normal low.

Where Homer Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 16°F.
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 181 nights a year, more than most ranked stations.
Homer earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Homer spreads its precipitation across the year
Neither half of the year dominates here: June through August take 19% of the annual total and December through February 30%, with neither reaching the 35% that would mark a distinct wet season. Homer has no dry season to plan around, though it does carry a 30.7°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 3.3" and May 0.8". The three wettest months together take 39% 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.
Rain reaches Homer in small, frequent amounts
Homer records about 156 days with measurable precipitation a year and 23.9" in total, which works out to roughly 0.15 inches on an average wet day. Precipitation on 43% of all days, arriving that lightly, is the damp many-grey-days pattern rather than the storm-driven one.
Places in this band read as wetter than their annual totals suggest, because what people notice is the number of overcast days, not the depth in the gauge.
- Most wet days: December, about 17 of them.
- Fewest: May, about 10.
- Average depth per wet day: 0.15 inches.
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 Homer's climate pattern fits together
heating led · moderate · mid swing
Homer's energy balance leans toward cold weather: 9,084 annual heating degree days against 0 for cooling. Its 30.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 142 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.
July and January mark the typical warm and cold ends of the calendar in Homer's middle-range seasonal profile. The measured spread is 30.7°F. The annual average is 40°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Homer's 23.9 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 Homer'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 Homer, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Homer's primary station: HOMER AP (USW00025507). 3 NOAA stations are mapped to the Homer area; the primary station's record is used for consistency. For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 0233140). Match rule for Homer: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
