The year, day by day
Alkali Lake works both ends of the calendar. Normal highs climb to 91°F by July 26 and hold at or above 90°F on 14 dates, then normal lows drop to freezing or below on 212 dates, bottoming at 19°F around December 14.
When the heat sits
Normal highs reach 90°F from July 21 through August 3, covering 14 dates. The broader mild season, normal highs of 70°F or more, runs May 29 to October 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.
The freezing stretch
The normal low stays at or below 32°F into May 2, then returns to freezing around October 4, covering 212 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
July 23 carries the biggest normal gap between afternoon and dawn, 41°F between the normal high and the normal low.

Where Alkali Lake Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 212 nights a year, placing this among the most frost-prone tenth of ranked stations.
Aridity defines the water calendar: about 11 inches in a normal year lands this among the driest tenth of ranked stations.
Alkali Lake earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Alkali Lake spreads its precipitation across the year
Neither half of the year dominates here: June through August take 15% of the annual total and December through February 31%, with neither reaching the 35% that would mark a distinct wet season. Alkali Lake has no dry season to plan around, though it does carry a 37.7°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 1.6" and August 0.3". The three wettest months together take 36% 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.

Scarce-water calendar
Where Alkali Lake's limited precipitation lands
heating led · dry · mid swing
Alkali Lake's energy balance leans toward cold weather: 6,939 annual heating degree days against 283 for cooling. Its 37.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 96 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and December mark the typical warm and cold ends of the calendar in Alkali Lake's middle-range seasonal profile. The measured spread is 37.7°F. The annual average is 47°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alkali Lake's cold-season load does not imply a wet climate. Annual precipitation is 11.3 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Alkali Lake's primary station: ALKALI LAKE (USC00350118). 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 Alkali Lake; 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 Alkali Lake comes from its primary NOAA station record.
