The year, day by day
The calendar barely moves in Chisos Basin: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 38°F near January 3 and 87°F near June 9.
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 38°F around January 3.
Where the wet dates fall
The likeliest wet date is July 7, when 29% of years recorded at least a hundredth of an inch. The driest is March 24 at 8%. Summed across the calendar, that is about 60 wet dates a year.
The widest day
April 4 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Chisos Basin runs a summer-peaked wet season
51% of Chisos Basin'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 July at 3.6", on an unusually narrow 27.9°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: July, August, June, taking 51% of the annual total between them.
- Driest month: December at 0.5".
- 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.
How Chisos Basin's precipitation splits across the calendar
About 60 days a year record measurable precipitation here, carrying 18.3" between them, or roughly 0.30 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.

Data-derived climate profile
How Chisos Basin's climate pattern fits together
mixed demand · dry · low swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 18.3 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.
The calendar stays thermally compact and dry. June and January mark the typical warm and cold ends of the calendar, only 27.9°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 63°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
Chisos Basin combines a compact 27.9°F annual temperature range with meaningful demand on both sides of the thermostat: 2,198 heating and 1,456 cooling degree days. The balance matters more here than either annual total in isolation.
Chisos Basin has a long frost-free window of roughly 254 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.
These labels group NOAA 1991-2020 normals from Chisos Basin's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Chisos Basin, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Chisos Basin's primary station: CHISOS BASIN (USC00411715). 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 Chisos Basin; 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 Chisos Basin comes from its primary NOAA station record.
