The year, day by day
The calendar barely moves in Grizzly Creek State Park: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 37°F near December 14 and 74°F near July 24.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 37°F around December 14.
Where the wet dates fall
The likeliest wet date is January 22, when 52% of years recorded at least a hundredth of an inch. The driest is July 30 at 6%. Summed across the calendar, that is about 114 wet dates a year.
The widest day
September 13 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Grizzly Creek State Park's wet season runs through the cold months
December, January and February carry 54% of the year's precipitation here, while June through August contribute 2%. 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 20.2°F seasonal spread.
- Wettest month
- December, 10.7"
- Driest month
- August, 0.1"
- Wettest three months
- December, February, January (54% 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.
When it rains in Grizzly Creek State Park, it arrives in quantity
52.3" of precipitation falls across only about 112 wet days here, averaging 0.46 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 112 a year, 31% of all days
- Average depth per wet day
- 0.46 inches
- Most wet days
- January, about 16
- Fewest wet days
- August, about 2
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.
Snow reaches Grizzly Creek State Park, but rarely amounts to much
The normals record 0.7 inches of snow a year here, most likely in March. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 1 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Grizzly Creek State Park's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Grizzly Creek State Park, at 4,430 degree days versus 34 for cooling. Unlike a strongly continental record, however, its 20.2°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
The frost-free window extends for about 263 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
Grizzly Creek State Park's 20.2°F seasonal spread is compact even though precipitation is abundant. August and December mark the typical warm and cold ends of the calendar. The annual average is 53°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
Alongside its heating load, Grizzly Creek State Park carries 52.3 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 0.7 inches. 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 Grizzly Creek State Park'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 Grizzly Creek State Park, 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 Grizzly Creek State Park's primary station: GRIZZLY CREEK SP (USC00043647). 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 Grizzly Creek State Park; 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 Grizzly Creek State Park comes from its primary NOAA station record.
