The year, day by day
The year in Wfo Brownsville runs from a mild 50°F around January 8 to 95°F at the peak near August 12, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 1 through September 12, covering 104 dates. The broader mild season, normal highs of 70°F or more, runs January 16 to December 29.
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.
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 50°F around January 8.
The widest day
February 1 carries the biggest normal gap between afternoon and dawn, 20°F between the normal high and the normal low.

Where Wfo Brownsville Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 104 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 20°F.
Wfo Brownsville earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Data-derived climate profile
How Wfo Brownsville's climate pattern fits together
cooling led · low swing
Warm-season load persists through a relatively even calendar in Wfo Brownsville. Cooling totals 3,920 degree days, more than double the 497 heating measure, and the 25.2°F seasonal range is compact rather than sharply divided.
A moisture-range label is withheld because Wfo Brownsville's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
Temperature varies within a narrow 25.2°F band across the normal year. August and January mark the typical warm and cold ends of the calendar. The annual average is 74°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
A frost-free growing-season length is not available for Wfo Brownsville. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
These labels group NOAA 1991-2020 normals from Wfo Brownsville's primary station, so the summer figures are a thirty-year average rather than a ceiling: individual years have run hotter and will again. For Wfo Brownsville that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Wfo Brownsville's primary station: WFO BROWNSVILLE (USC00419649). 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 Wfo Brownsville; 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 Wfo Brownsville comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
