The year, day by day
The year in Stillhouse Hollow Dam runs from a mild 35°F around January 8 to 97°F at the peak near August 4, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 8 through September 15, covering 100 dates. The broader mild season, normal highs of 70°F or more, runs March 15 to November 13.
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 35°F around January 8.
Where the wet dates fall
The likeliest wet date is March 2, when 30% of years recorded at least a hundredth of an inch. The driest is July 30 at 14%. Summed across the calendar, that is about 87 wet dates a year.
The widest day
February 5 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Where Stillhouse Hollow Dam Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 100 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Stillhouse Hollow Dam earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Stillhouse Hollow Dam spreads its precipitation across the year
Neither half of the year dominates here: June through August take 21% of the annual total and December through February 21%, with neither reaching the 35% that would mark a distinct wet season. Stillhouse Hollow Dam has no dry season to plan around, though it does carry a 36.1°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 4.8" and July 1.9". The three wettest months together take 34% 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.
When it rains in Stillhouse Hollow Dam, it arrives in quantity
37.0" of precipitation falls across only about 87 wet days here, averaging 0.43 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 87 a year, 24% of all days
- Average depth per wet day
- 0.43 inches
- Most wet days
- March, about 9
- Fewest wet days
- August, about 5
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.
Stillhouse Hollow Dam'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 Stillhouse Hollow Dam's climate pattern fits together
mixed demand · moderate · mid swing
August and January mark the typical warm and cold ends of the calendar in Stillhouse Hollow Dam's middle-range seasonal profile. The measured spread is 36.1°F. The annual average is 67°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Stillhouse Hollow Dam's normal, at 2,032 and 2,630 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
The frost-free window extends for about 251 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.
Stillhouse Hollow Dam's 37.0 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 Stillhouse Hollow Dam's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Stillhouse Hollow Dam, the bands are descriptive ranges rather than an official NOAA classification or a 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 Stillhouse Hollow Dam; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
