7° on Nov. 12, 2019, the coldest reading for this week of the year since 1994. Next is 13° in 2018.
Wooldridge’s center stands about 590 ft above sea level. Within three miles the land runs from 560 ft to 810 ft, a difference of 250 ft: rolling country.
Under the town center the state geologic map shows Kinderhookian Series (limestone, siltstone), 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 60×. 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: Carboniferous, 324 to 359 million years old. About 14 mi of the line.
Shale, sandstone, siltstone. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Limestone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.

A raindrop that lands in Wooldridge reaches the Gulf of America by way of Petite Saline Creek, the Missouri and the Mississippi: about 1,340 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wooldridge; river miles along the main stem, rounded.
Wooldridge has a hot-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 22° in January. A normal year brings about 17 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Wooldridge normally reaches 55° and falls to 37°. The record high is 79°, in 2025; the record low 13°, in 2018. The most rain on this date, 0.18 in, fell in 2024.
Normals 1991–2020 and records since 1994 at Columbia U Of M, 11 miles east-northeast, 180 ft higher. NOAA, through RCC-ACIS.
