3.95 inches of rain fell in two days, the most for this week of the year since records began in 1961. The next wettest, 3.67 inches, fell in 2004.
Wimberley’s center stands about 870 ft above sea level. Within three miles the land runs from 820 ft to 1,190 ft, a difference of 370 ft: rolling country. The highest named summit within 15 miles is Mount Sharp, about 1,510 ft, 10 miles northwest.
Under the town center the state geologic map shows Glen Rose Limestone (limestone, marlstone), from the Early Cretaceous, 100 to 145 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 22×. 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, marlstone. Age: Early Cretaceous, 100 to 145 million years old. About 15 mi of the line.
Limestone. Age: Early Cretaceous, 100 to 113 million years old. About 8 mi of the line.
Clay, limestone. Age: Late Cretaceous, 66 to 100 million years old. About 0.9 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.3 mi of the line.

A raindrop that lands in Wimberley reaches the Gulf of America by way of Pierce Creek, the Blanco, the San Marcos, the Guadalupe and the South Guadalupe: about 280 river miles.
180 miles of the trip are on the Guadalupe.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wimberley; river miles along the main stem, rounded.
Wimberley has a humid subtropical climate. Summer afternoons average 95° in August; winter nights fall to about 40° in January. About 38 inches of rain fall in a normal year.
On November 14 Wimberley normally reaches 70° and falls to 50°. The record high is 86°, in 2011; the record low 27°, in 2018. The most rain on this date, 0.60 in, fell in 2004.
Normals 1991–2020 and records since 1961 at Canyon Dam, 11 miles south-southwest, 130 ft higher. NOAA, through RCC-ACIS.
