The year, day by day
Summer here tops out rather than builds: the warmest normal high is 90°F around July 27, short of 90°F on every date, while 196 dates carry a normal low at or below freezing, the coldest 4°F near January 10.
The freezing stretch
The normal low stays at or below 32°F into April 24, then returns to freezing around October 12, covering 196 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 June 9, when 39% of years recorded at least a hundredth of an inch. The driest is November 25 at 18%. Summed across the calendar, that is about 91 wet dates a year.
The widest day
August 28 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Jordan Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 196 nights a year, more than most ranked stations.
A drier-than-most normal water year — around 13 inches, below what four out of five ranked stations collect.
Jordan earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Jordan runs a summer-peaked wet season
40% of Jordan'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 2.5", on a wide 53.5°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, May, July, taking 47% of the annual total between them.
- Driest month: December at 0.4".
- Winter share: 9% 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.
Jordan is dry, and what does fall arrives gently
Only about 90 days a year record measurable precipitation here, 25% of the calendar, and they carry 12.9" between them. At roughly 0.14 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 June at about 11 wet days; the driest is November 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.

Scarce-water calendar
Where Jordan's limited precipitation lands
heating led · dry · mid swing
Jordan's energy balance leans toward cold weather: 8,043 annual heating degree days against 491 for cooling. Its 53.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 125 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 Jordan's middle-range seasonal profile. The measured spread is 53.5°F. The annual average is 44°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Jordan's cold-season load does not imply a wet climate. Annual precipitation is 12.9 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 3039925). Match rule for Jordan: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
