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

The year, day by day
Bullfrog Basin works both ends of the calendar. Normal highs climb to 100°F by July 13 and hold at or above 90°F on 99 dates, then normal lows drop to freezing or below on 98 dates, bottoming at 25°F around December 25.
When the heat sits
Normal highs reach 90°F from June 5 through September 11, covering 99 dates. The broader mild season, normal highs of 70°F or more, runs April 9 to October 23.
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 26, then returns to freezing around November 21, covering 98 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.
Where the wet dates fall
The likeliest wet date is February 23, when 15% of years recorded at least a hundredth of an inch. The driest is June 20 at 4%. Summed across the calendar, that is about 40 wet dates a year.
The widest day
June 13 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Where Bullfrog Basin Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 99 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 6 inches in a normal year lands this among the driest tenth of ranked stations.
Bullfrog Basin earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Bullfrog Basin spreads its precipitation across the year
Neither half of the year dominates here: June through August take 20% of the annual total and December through February 25%, with neither reaching the 35% that would mark a distinct wet season. Bullfrog Basin has no dry season to plan around, though it does carry a wide 49.6°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: September averages 0.8" and June 0.1". The three wettest months together take 35% 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.
Bullfrog Basin is dry, and what does fall arrives gently
Only about 40 days a year record measurable precipitation here, 11% of the calendar, and they carry 6.4" between them. At roughly 0.16 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 January at about 4 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.
Snow reaches Bullfrog Basin, but rarely amounts to much
The normals record 4.0 inches of snow a year here, most likely in December. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 3 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Scarce-water calendar
Where Bullfrog Basin's limited precipitation lands
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 6.4 inches annually, within PlainClimate's dry band. Annual snowfall totals 4.0 inches. 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 Bullfrog Basin's middle-range seasonal profile. The measured spread is 49.6°F. The annual average is 60°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Bullfrog Basin's normal, at 4,009 and 2,069 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 230-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.

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 Bullfrog Basin; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
