The year, day by day
Summer here tops out rather than builds: the warmest normal high is 80°F around July 13, short of 90°F on every date, while 189 dates carry a normal low at or below freezing, the coldest 4°F near January 30.
The freezing stretch
The normal low stays at or below 32°F into April 28, then returns to freezing around October 23, covering 189 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 September 7, when 39% of years recorded at least a hundredth of an inch. The driest is February 9 at 17%. Summed across the calendar, that is about 104 wet dates a year.
The widest day
May 13 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Where Iron Mtn Ford Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 189 nights a year, more than most ranked stations.
Iron Mtn Ford earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Iron Mtn Ford runs a summer-peaked wet season
39% of Iron Mtn Ford's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is June at 3.0", on a wide 52.6°F gap between its warmest and coldest month. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: June, September, July, taking 42% of the annual total between them.
- Driest month: January at 0.5".
- Winter share: 8% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
Iron Mtn Ford is dry, and what does fall arrives gently
Only about 104 days a year record measurable precipitation here, 28% of the calendar, and they carry 20.7" between them. At roughly 0.20 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 September at about 12 wet days; the driest is February at about 5.
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.

Data-derived climate profile
How Iron Mtn Ford's climate pattern fits together
heating led · moderate · mid swing
Iron Mtn Ford's energy balance leans toward cold weather: 8,708 annual heating degree days against 296 for cooling. Its 52.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 122 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and January mark the typical warm and cold ends of the calendar in Iron Mtn Ford's middle-range seasonal profile. The measured spread is 52.6°F. The annual average is 42°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Iron Mtn Ford's 20.8 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Iron Mtn Ford's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Iron Mtn Ford, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Iron Mtn Ford's primary station: IRON MTN FORD AP (USW00094893). 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 Iron Mtn Ford; 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 Iron Mtn Ford comes from its primary NOAA station record.
