The year, day by day
Summer here tops out rather than builds: the warmest normal high is 78°F around July 21, short of 90°F on every date, while 184 dates carry a normal low at or below freezing, the coldest 3°F near January 18.
The freezing stretch
The normal low stays at or below 32°F into April 25, then returns to freezing around October 25, covering 184 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.
The widest day
June 26 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Where Bayfield Fish Hatchery Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 184 nights a year, more than most ranked stations.
Days and nights track unusually close together; the widest normal swing, about 22°F, is narrower than most stations record.
Bayfield Fish Hatchery earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Bayfield Fish Hatchery spreads its precipitation across the year
Neither half of the year dominates here: June through August take 35% of the annual total and December through February 15%, with neither reaching the 35% that would mark a distinct wet season. Bayfield Fish Hatchery has no dry season to plan around, though it does carry a wide 53.6°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: June averages 3.9" and February 1.3". The three wettest months together take 35% 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.

Data-derived climate profile
How Bayfield Fish Hatchery's climate pattern fits together
heating led · moderate · mid swing
Bayfield Fish Hatchery's energy balance leans toward cold weather: 8,905 annual heating degree days against 210 for cooling. Its 53.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 132 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 Bayfield Fish Hatchery's middle-range seasonal profile. The measured spread is 53.6°F. The annual average is 41°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Bayfield Fish Hatchery's 32.6 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 Bayfield Fish Hatchery'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 Bayfield Fish Hatchery, 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 Bayfield Fish Hatchery's primary station: BAYFIELD FISH HATCHERY (USC00470604). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Bayfield Fish Hatchery; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Bayfield Fish Hatchery comes from its primary NOAA station record.
