The year, day by day
S Lake FS works both ends of the calendar. Normal highs climb to 99°F by July 21 and hold at or above 90°F on 104 dates, then normal lows drop to freezing or below on 70 dates, bottoming at 29°F around January 1.
When the heat sits
Normal highs reach 90°F from June 9 through September 20, covering 104 dates. The broader mild season, normal highs of 70°F or more, runs April 5 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.
The freezing stretch
The normal low stays at or below 32°F into February 4, then returns to freezing around November 27, covering 70 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
October 24 carries the biggest normal gap between afternoon and dawn, 39°F between the normal high and the normal low.

Where S Lake FS Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 104 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 39°F, sharper than nine in ten ranked stations see.
S Lake FS earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Data-derived climate profile
How S Lake FS's climate pattern fits together
mixed demand · mid swing
July and December mark the typical warm and cold ends of the calendar in S Lake FS's middle-range seasonal profile. The measured spread is 37.7°F. The annual average is 61°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in S Lake FS's normal, at 3,079 and 1,723 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.
A roughly 212-day frost-free season sits inside this mixed heating-and-cooling profile. Start and end dates matter because both sides of the thermostat register during a normal year.
A moisture-range label is withheld because S Lake FS's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from S Lake FS'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 S Lake FS, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from S Lake FS's primary station: S LAKE FS (USC00048407). 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 S Lake FS; 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 S Lake FS comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
