Boquillas Ranger Station's normals sit in a dry climate class: BWh
Annual precipitation falls well below the aridity threshold for this temperature regime, so the normals classify as hot desert (BWh). Class BWh is the Peel et al. (2007) label for this station's monthly mean temperature and precipitation normals: dry (arid or semi-arid), specifically hot desert.

The year, day by day
Boquillas Ranger Station works both ends of the calendar. Normal highs climb to 105°F by June 12 and hold at or above 90°F on 194 dates, then normal lows drop to freezing or below on 54 dates, bottoming at 29°F around January 5.
When the heat sits
Normal highs reach 90°F from April 4 through October 14, covering 194 dates. The broader mild season, normal highs of 70°F or more, runs January 16 to December 11.
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 1, then returns to freezing around December 10, covering 54 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 18, when 18% of years recorded at least a hundredth of an inch. The driest is April 11 at 6%. Summed across the calendar, that is about 39 wet dates a year.
The widest day
April 5 carries the biggest normal gap between afternoon and dawn, 41°F between the normal high and the normal low.

Where Boquillas Ranger Station Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 194 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 9 inches in a normal year lands this among the driest tenth of ranked stations.
Boquillas Ranger Station earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Boquillas Ranger Station runs a summer-peaked wet season
42% of Boquillas Ranger Station'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 1.4", on a 38.5°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, June, May, taking 44% of the annual total between them.
- Driest month: March at 0.3".
- Winter share: 13% 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 Boquillas Ranger Station's precipitation splits across the calendar
About 39 days a year record measurable precipitation here, carrying 8.7" between them, or roughly 0.22 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.
Boquillas Ranger Station's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Scarce-water calendar
Where Boquillas Ranger Station's limited precipitation lands
cooling led · dry · mid swing
Air-conditioning demand is the clearest thermal signal here. Boquillas Ranger Station accumulates 3,665 cooling degree days, more than twice its 1,530 heating total; the monthly table shows when that imbalance builds rather than treating it as a year-round condition.
Heat demand sits beside limited local precipitation: Boquillas Ranger Station receives 8.7 inches in a normal year, inside PlainClimate's dry range. Recorded annual snowfall is negligible. Month-level precipitation is the useful check on when that small annual total arrives.
June and January mark the typical warm and cold ends of the calendar in Boquillas Ranger Station's middle-range seasonal profile. The measured spread is 38.5°F. The annual average is 71°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Boquillas Ranger Station has a long frost-free window of roughly 248 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.

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 Boquillas Ranger Station; 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 Boquillas Ranger Station comes from its primary NOAA station record.
