Beaver Dam's normals sit in a dry climate class: BWh
Annual precipitation falls well below the aridity threshold for this temperature regime, so the normals classify as hot desert (BWh). Class BWh is the Peel et al. (2007) label for this station's monthly mean temperature and precipitation normals: dry (arid or semi-arid), specifically hot desert.

The year, day by day
Beaver Dam works both ends of the calendar. Normal highs climb to 109°F by July 16 and hold at or above 90°F on 150 dates, then normal lows drop to freezing or below on 22 dates, bottoming at 31°F around December 15.
When the heat sits
Normal highs reach 90°F from May 11 through October 7, covering 150 dates. The broader mild season, normal highs of 70°F or more, runs March 2 to November 19.
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
Freezing normal lows set in around December 9, covering 22 dates.
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.
Where the wet dates fall
The likeliest wet date is February 21, when 20% of years recorded at least a hundredth of an inch. The driest is June 15 at 4%. Summed across the calendar, that is about 42 wet dates a year.
The widest day
June 21 carries the biggest normal gap between afternoon and dawn, 40°F between the normal high and the normal low.

Where Beaver Dam Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 150 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Aridity defines the water calendar: about 7 inches in a normal year lands this among the driest tenth of ranked stations.
Beaver Dam earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Beaver Dam's wet season runs through the cold months
December, January and February carry 41% of the year's precipitation here, while June through August contribute 14%. 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 wide 45.4°F gap between its warmest and coldest month.

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.
Beaver Dam is dry, and what does fall arrives gently
Only about 42 days a year record measurable precipitation here, 12% of the calendar, and they carry 7.0" between them. At roughly 0.17 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.
The wettest month by count is February at about 6 wet days; the driest is June at about 1.
A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.

Scarce-water calendar
Where Beaver Dam's limited precipitation lands
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 7.0 inches annually, within PlainClimate's dry band. Snowfall is not added to the interpretation because its annual value is missing. The monthly distribution matters because the total alone does not reveal the timing.
July and December mark the typical warm and cold ends of the calendar in Beaver Dam's middle-range seasonal profile. The measured spread is 45.4°F. The annual average is 68°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Beaver Dam's normal, at 2,182 and 3,349 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.
Beaver Dam has a long frost-free window of roughly 257 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.
