Painted Rock 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
The year in Painted Rock Dam runs from a mild 39°F around December 21 to 108°F at the peak near July 4, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from April 28 through October 18, covering 174 dates. The broader mild season, normal highs of 70°F or more, runs January 22 to December 5.
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 39°F around December 21.
Where the wet dates fall
The likeliest wet date is August 18, when 11% of years recorded at least a hundredth of an inch. The driest is June 1 at 1%. Summed across the calendar, that is about 20 wet dates a year.
The widest day
June 8 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Painted Rock Dam Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 174 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.
Painted Rock Dam earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Painted Rock Dam spreads its precipitation across the year
Neither half of the year dominates here: June through August take 29% of the annual total and December through February 30%, with neither reaching the 35% that would mark a distinct wet season. Painted Rock Dam has no dry season to plan around, though it does carry a 40.6°F seasonal spread.
The gap between the wettest and driest month still matters: July averages 0.9" and June 0.0". The three wettest months together take 40% 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.
How Painted Rock Dam's precipitation splits across the calendar
About 20 days a year record measurable precipitation here, carrying 6.1" 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.
Painted Rock Dam's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Scarce-water calendar
Where Painted Rock Dam's limited precipitation lands
cooling led · dry · mid swing
Air-conditioning demand is the clearest thermal signal here. Painted Rock Dam accumulates 4,366 cooling degree days, more than twice its 1,063 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: Painted Rock Dam receives 6.1 inches in a normal year, inside PlainClimate's dry range. Recorded annual snowfall is negligible. 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 Painted Rock Dam's middle-range seasonal profile. The measured spread is 40.6°F. The annual average is 74°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Painted Rock Dam has a long frost-free window of roughly 328 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.

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 Painted Rock Dam; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
