81° on Nov. 11, 2002, the hottest reading for this week of the year since 1964. Next is 80° in 1989.
Brownsville’s center stands about 650 ft above sea level. Within three miles the land runs from 440 ft to 800 ft, a difference of 360 ft: rolling country. The highest named summit within 15 miles is Pilot Knob, about 970 ft, 12 miles south-southeast.
Under the town center the state geologic map shows Rocks of Chesterian age, lower part (limestone, sandstone), from the Carboniferous, 324 to 359 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 40×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, sandstone. Age: Carboniferous, 324 to 359 million years old. About 12 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 9 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.6 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 0.4 mi of the line.

A raindrop that lands in Brownsville reaches the Gulf of America by way of the Green River, the Ohio and the Mississippi: about 1,350 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Brownsville; river miles along the main stem, rounded.
Brownsville has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 24° in January. About 54 inches of rain fall in a normal year, with about 5 inches of snow.
On November 14 Brownsville normally reaches 61° and falls to 34°. The record high is 77°, in 1989; the record low 12°, in 1986. The most rain on this date, 2.18 in, fell in 2024.
