The year, day by day
Jemez Dam works both ends of the calendar. Normal highs climb to 93°F by July 4 and hold at or above 90°F on 67 dates, then normal lows drop to freezing or below on 127 dates, bottoming at 22°F around January 5.
When the heat sits
Normal highs reach 90°F from June 14 through August 19, covering 67 dates. The broader mild season, normal highs of 70°F or more, runs April 17 to October 19.
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.
The freezing stretch
The normal low stays at or below 32°F into March 12, then returns to freezing around November 7, covering 127 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 July 27, when 27% of years recorded at least a hundredth of an inch. The driest is November 10 at 7%. Summed across the calendar, that is about 49 wet dates a year.
The widest day
June 10 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Where Jemez Dam Stands Nationally
Aridity defines the water calendar: about 9 inches in a normal year lands this among the driest tenth of ranked stations.
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 67 days a year, more than four out of five ranked stations record.

Jemez Dam runs a summer-peaked wet season
41% of Jemez Dam'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 August at 1.9", on a 44°F seasonal spread. 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: August, July, October, taking 47% of the annual total between them.
- Driest month: February at 0.3".
- Winter share: 15% 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.
Jemez Dam is dry, and what does fall arrives gently
Only about 50 days a year record measurable precipitation here, 14% of the calendar, and they carry 8.9" between them. At roughly 0.18 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 July at about 8 wet days; the driest is November at about 2.
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.
Snow reaches Jemez Dam, but rarely amounts to much
The normals record 5.7 inches of snow a year here, most likely in December. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 3 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Scarce-water calendar
Where Jemez Dam's limited precipitation lands
heating led · dry · mid swing
Jemez Dam's energy balance leans toward cold weather: 4,549 annual heating degree days against 1,258 for cooling. Its 44.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Jemez Dam's frost-free season lasts about 190 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Jemez Dam's middle-range seasonal profile. The measured spread is 44.0°F. The annual average is 56°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Jemez Dam's cold-season load does not imply a wet climate. Annual precipitation is 8.9 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 5.7 inches. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

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