The year, day by day
The year in Stony Gorge Rsvr runs from a mild 33°F around December 21 to 97°F at the peak near July 20, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 19 through September 17, covering 91 dates. The broader mild season, normal highs of 70°F or more, runs April 16 to November 2.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
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 33°F around December 21.
Where the wet dates fall
The likeliest wet date is January 8, when 38% of years recorded at least a hundredth of an inch. The driest is July 25 at 1%. Summed across the calendar, that is about 68 wet dates a year.
The widest day
September 6 carries the biggest normal gap between afternoon and dawn, 37°F between the normal high and the normal low.

Where Stony Gorge Rsvr Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 37°F, sharper than nine in ten ranked stations see.
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 91 days a year, more than four out of five ranked stations record.
Stony Gorge Rsvr earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Stony Gorge Rsvr's wet season runs through the cold months
December, January and February carry 59% of the year's precipitation here, while June through August contribute 3%. 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 a 34.1°F seasonal spread.
- Wettest month
- January, 4.5"
- Driest month
- August, 0.1"
- Wettest three months
- January, February, December (59% 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 Stony Gorge Rsvr's precipitation splits across the calendar
About 68 days a year record measurable precipitation here, carrying 21.4" between them, or roughly 0.32 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.
Stony Gorge Rsvr's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Data-derived climate profile
How Stony Gorge Rsvr's climate pattern fits together
heating led · moderate · mid swing
Stony Gorge Rsvr's energy balance leans toward cold weather: 3,190 annual heating degree days against 1,364 for cooling. Its 34.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Stony Gorge Rsvr's frost-free season lasts about 222 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and December mark the typical warm and cold ends of the calendar in Stony Gorge Rsvr's middle-range seasonal profile. The measured spread is 34.1°F. The annual average is 60°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Stony Gorge Rsvr's 21.4 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Recorded annual snowfall is negligible. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Stony Gorge Rsvr'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 Stony Gorge Rsvr, not an official NOAA class or a year-ahead forecast.

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 Stony Gorge Rsvr; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
