87° on Nov. 11, 2020, the hottest reading for this week of the year since 1892. Next is 86° in 1958.
Vienna’s center stands about 330 ft above sea level. Within three miles the land runs from 310 ft to 390 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Suwannee Limestone and its residuum, from the Oligocene, 23 to 34 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 64×. 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. Age: Oligocene, 23 to 34 million years old. About 11 mi of the line.
Sandstone, shale. Age: Eocene, 34 to 56 million years old. About 5 mi of the line.
Limestone. Age: Eocene, 34 to 56 million years old. About 5 mi of the line.
Fine-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Sandstone, claystone. Age: Tertiary Neogene, 2.6 to 23 million years old. About 1 mi of the line.

A raindrop that lands in Vienna reaches the Gulf of America by way of Pennahatchee Creek, Turkey Creek, the Flint and the Apalachicola: about 270 river miles.
150 miles of the trip are on the Flint.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Vienna; river miles along the main stem, rounded.
Vienna has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 36° in January. About 50 inches of rain fall in a normal year.
On November 14 Vienna normally reaches 69° and falls to 44°. The record high is 83°, in 1955; the record low 26°, in 1984. The most rain on this date, 1.25 in, fell in 2008.
Normals 1991–2020 and records since 1892 at Cordele, 7 miles south. NOAA, through RCC-ACIS.
