Eagle Mtn'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 Eagle Mtn runs from a mild 45°F around December 21 to 104°F at the peak near July 15, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from May 17 through October 5, covering 142 dates. The broader mild season, normal highs of 70°F or more, runs February 26 to November 22.
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 45°F around December 21.
Where the wet dates fall
The likeliest wet date is February 19, when 10% of years recorded at least a hundredth of an inch. The driest is June 2 at 1%. Summed across the calendar, that is about 17 wet dates a year.
The widest day
June 15 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Where Eagle Mtn Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 142 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 4 inches in a normal year lands this among the driest tenth of ranked stations.
Eagle Mtn earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Eagle Mtn's wet season runs through the cold months
December, January and February carry 50% of the year's precipitation here, while June through August contribute 19%. 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 39.3°F seasonal spread.
- Wettest month
- December, 0.6"
- Driest month
- June, 0.0"
- Wettest three months
- December, February, January (50% 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 Eagle Mtn's precipitation splits across the calendar
About 17 days a year record measurable precipitation here, carrying 3.6" between them, or roughly 0.21 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.
Eagle Mtn'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 Eagle Mtn's limited precipitation lands
cooling led · dry · mid swing
Air-conditioning demand is the clearest thermal signal here. Eagle Mtn accumulates 4,237 cooling degree days, more than twice its 1,071 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: Eagle Mtn receives 3.6 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 Eagle Mtn's middle-range seasonal profile. The measured spread is 39.3°F. The annual average is 74°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A frost-free growing-season length is not available for Eagle Mtn. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.

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