Scottsdale Muni'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 Scottsdale Muni runs from a mild 42°F around December 18 to 105°F at the peak near July 2, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from May 12 through October 8, covering 150 dates. The broader mild season, normal highs of 70°F or more, runs February 24 to November 25.
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 42°F around December 18.
Where the wet dates fall
The likeliest wet date is July 31, when 15% of years recorded at least a hundredth of an inch. The driest is June 2 at 2%. Summed across the calendar, that is about 34 wet dates a year.
The widest day
June 6 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Where Scottsdale Muni 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 9 inches in a normal year lands this among the driest tenth of ranked stations.
Scottsdale Muni earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Scottsdale Muni's wet season runs through the cold months
December, January and February carry 38% of the year's precipitation here, while June through August contribute 20%. 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 39.8°F seasonal spread.
- Wettest month
- February, 1.2"
- Driest month
- June, 0.1"
- Wettest three months
- February, January, March (40% 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 Scottsdale Muni's precipitation splits across the calendar
About 34 days a year record measurable precipitation here, carrying 8.7" between them, or roughly 0.26 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 Scottsdale Muni's limited precipitation lands
cooling led · dry · mid swing
Air-conditioning demand is the clearest thermal signal here. Scottsdale Muni accumulates 4,170 cooling degree days, more than twice its 1,139 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: Scottsdale Muni receives 8.7 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 Scottsdale Muni's middle-range seasonal profile. The measured spread is 39.8°F. The annual average is 73°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
With about 354 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 Scottsdale Muni.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Scottsdale Muni's primary station: SCOTTSDALE MUNI AP (USW00003192). 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 Scottsdale Muni; 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 Scottsdale Muni comes from its primary NOAA station record.
