The year, day by day
Summer here tops out rather than builds: the warmest normal high is 61°F around July 28, short of 90°F on every date, while 146 dates carry a normal low at or below freezing, the coldest 28°F near January 18.
The freezing stretch
The normal low stays at or below 32°F into April 8, then returns to freezing around November 15, covering 146 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
May 8 carries the biggest normal gap between afternoon and dawn, 13°F between the normal high and the normal low.

Where Hidden Falls Hatchery Stands Nationally
This is one of the wettest normals climates ranked: about 128 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 13°F.
Hidden Falls 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
Hidden Falls Hatchery spreads its precipitation across the year
Neither half of the year dominates here: June through August take 12% of the annual total and December through February 32%, with neither reaching the 35% that would mark a distinct wet season. Hidden Falls Hatchery has no dry season to plan around, though it does carry an unusually narrow 23.7°F seasonal spread.
The gap between the wettest and driest month still matters: November averages 19.0" and June 4.0". The three wettest months together take 41% 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 Hidden Falls Hatchery's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Hidden Falls Hatchery, at 8,252 degree days versus 0 for cooling. Unlike a strongly continental record, however, its 23.7°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Hidden Falls Hatchery's frost-free season lasts about 179 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Hidden Falls Hatchery's 23.7°F seasonal spread is compact even though precipitation is abundant. July and January mark the typical warm and cold ends of the calendar. The annual average is 42°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
Alongside its heating load, Hidden Falls Hatchery carries 128.1 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 Hidden Falls 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 Hidden Falls 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 Hidden Falls Hatchery's primary station: HIDDEN FALLS HATCHERY (USC00503605). 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 Hidden Falls 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 Hidden Falls Hatchery comes from its primary NOAA station record.
