Bullhead City'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
The year in Bullhead City runs from a mild 43°F around December 16 to 111°F at the peak near July 12, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from April 27 through October 14, covering 171 dates. The broader mild season, normal highs of 70°F or more, runs February 17 to November 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.
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 43°F around December 16.
Where the wet dates fall
The likeliest wet date is February 15, when 10% of years recorded at least a hundredth of an inch. The driest is June 5 at 1%. Summed across the calendar, that is about 18 wet dates a year.
The widest day
June 15 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Bullhead City Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 171 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 5 inches in a normal year lands this among the driest tenth of ranked stations.
Bullhead City earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Bullhead City's wet season runs through the cold months
December, January and February carry 49% of the year's precipitation here, while June through August contribute 13%. 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 42.2°F seasonal spread.

- February, 1.1"
- Driest month
- June, 0.0"
- Wettest three months
- February, January, March (54% of the year)
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.
How Bullhead City's precipitation splits across the calendar
About 18 days a year record measurable precipitation here, carrying 5.4" between them, or roughly 0.30 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.

Scarce-water calendar
Where Bullhead City's limited precipitation lands
cooling led · dry · mid swing
Air-conditioning demand is the clearest thermal signal here. Bullhead City accumulates 4,503 cooling degree days, more than twice its 1,100 heating total; the monthly table shows when that imbalance builds rather than treating it as a year-round condition.
Heat demand sits beside limited local precipitation: Bullhead City receives 5.4 inches in a normal year, inside PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. Month-level precipitation is the useful check on when that small annual total arrives.
July and December mark the typical warm and cold ends of the calendar in Bullhead City's middle-range seasonal profile. The measured spread is 42.2°F. The annual average is 74°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
With about 353 frost-free days, the calendar is constrained more by sustained heat than by freeze timing. This does not measure crop suitability or soil moisture; it only reports the NOAA-derived frost-free window for Bullhead City.
