Florence’s center stands about 1,000 ft above sea level. Within three miles the land runs from 910 ft to 1,090 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Pilot Knob, about 1,220 ft, 8 miles southwest.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 42×. 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, dolostone. Age: Early Cretaceous, 100 to 145 million years old. About 11 mi of the line.
Limestone, shale. Age: Early Cretaceous, 100 to 145 million years old. About 10 mi of the line.
Limestone, marlstone. Age: Early Cretaceous, 100 to 145 million years old. About 3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Florence reaches the Gulf of America by way of South Salado Creek, Salado Creek, the Little River and the Brazos: about 450 river miles.
320 miles of the trip are on the Brazos.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Florence; river miles along the main stem, rounded.
Florence has a humid subtropical climate. Summer afternoons average 97° in August; winter nights fall to about 36° in January. About 37 inches of rain fall in a normal year.
On November 14 Florence normally reaches 70° and falls to 47°. The record high is 86°, in 2006; the record low 26°, in 2018. The most rain on this date, 0.41 in, fell in 1998.
Normals 1991–2020 and records since 1980 at Georgetown Lake, 12 miles south-southeast, 130 ft lower. NOAA, through RCC-ACIS.
