Pecos's normals sit in a dry climate class: BSh
Precipitation is low relative to temperature but above true desert thresholds: hot semi-arid steppe (BSh). Class BSh is the Peel et al. (2007) label for this station's monthly mean temperature and precipitation normals: dry (arid or semi-arid), specifically hot semi-arid steppe.

The year, day by day
Pecos works both ends of the calendar. Normal highs climb to 99°F by June 15 and hold at or above 90°F on 128 dates, then normal lows drop to freezing or below on 63 dates, bottoming at 30°F around January 12.
When the heat sits
Normal highs reach 90°F from May 11 through September 15, covering 128 dates. The broader mild season, normal highs of 70°F or more, runs February 28 to November 12.
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 February 9, then returns to freezing around December 9, covering 63 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 12, when 14% of years recorded at least a hundredth of an inch. The driest is April 16 at 4%. Summed across the calendar, that is about 28 wet dates a year.
The widest day
April 24 carries the biggest normal gap between afternoon and dawn, 36°F between the normal high and the normal low.

Where Pecos Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 128 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 10 inches in a normal year lands this among the driest tenth of ranked stations.

Pecos spreads its precipitation across the year
Neither half of the year dominates here: June through August take 34% of the annual total and December through February 15%, with neither reaching the 35% that would mark a distinct wet season. Pecos has no dry season to plan around, though it does carry a 37.5°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 1.9" and April 0.2". The three wettest months together take 44% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
When it rains in Pecos, it arrives in quantity
10.1" of precipitation falls across only about 28 wet days here, averaging 0.36 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 28 a year, 8% of all days
- Average depth per wet day
- 0.36 inches
- Most wet days
- September, about 4
- Fewest wet days
- April, about 1
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Scarce-water calendar
Where Pecos's limited precipitation lands
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 10.1 inches annually, within PlainClimate's dry band. Snowfall is not added to the interpretation because its annual value is missing. The monthly distribution matters because the total alone does not reveal the timing.
July and January mark the typical warm and cold ends of the calendar in Pecos's middle-range seasonal profile. The measured spread is 37.5°F. The annual average is 65°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Pecos's normal, at 2,351 and 2,535 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
A roughly 237-day frost-free season sits inside this mixed heating-and-cooling profile. Start and end dates matter because both sides of the thermostat register during a normal year.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Pecos's primary station: PECOS 8W (USC00416893). 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 Pecos; 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 Pecos comes from its primary NOAA station record.
