79° on Nov. 17, 2016, the hottest reading for this week of the year since 1879. Next is 78° in 1955.
Spaulding’s center stands about 590 ft above sea level. Within three miles the land runs from 520 ft to 610 ft, a difference of 90 ft: gently rolling country. The highest named summit within 15 miles is Elkhart Hill, about 820 ft, 11 miles north-northeast.
Under the town center the state geologic map shows Shelburn-Patoka Formations undivided (shale, limestone), from the Late Pennsylvanian, 304 to 307 million years old.
The section below crosses 2 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.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 22 mi of the line.
Shale, sandstone, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 2 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 Spaulding reaches the Gulf of America by way of Wolf Creek, the Sangamon, the Illinois and the Mississippi: about 1,360 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Spaulding; river miles along the main stem, rounded.
Spaulding has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 20° in January. A normal year brings about 22 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Spaulding normally reaches 53° and falls to 35°. The record high is 78°, in 2025; the record low 12°, in 1940. The most rain on this date, 0.91 in, fell in 1993.
Normals 1991–2020 and records since 1879 from the Springfield Area threaded record (Springfield Abraham Lincoln Capital Airport, 8 miles west). NOAA, through RCC-ACIS.
