81° on Nov. 13, 1999, the hottest reading for this week of the year since 1878. Next is 76° in 2001.
New Virginia’s center stands about 1,080 ft above sea level. Within three miles the land runs from 900 ft to 1,080 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Marmaton Group (shale, limestone), from the Middle Pennsylvanian, 307 to 315 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 53×. 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: Middle Pennsylvanian, 307 to 315 million years old. About 14 mi of the line.
Shale, siltstone. Age: Middle Pennsylvanian, 307 to 315 million years old. About 5 mi of the line.
Shale, sandstone, siltstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 3 mi of the line.
Limestone, shale. Age: Middle Pennsylvanian to Late Pennsylvanian, 299 to 315 million years old. About 2 mi of the line.

A raindrop that lands in New Virginia reaches the Gulf of America by way of Squaw Creek, the South River, the Des Moines and the Mississippi: about 1,550 river miles.
Lake on the way: Roberts Creek.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of New Virginia; river miles along the main stem, rounded.
New Virginia has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 14° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 New Virginia normally reaches 49° and falls to 31°. The record high is 74°, in 2025; the record low −1°, in 1959. The most rain on this date, 0.86 in, fell in 1947.
Normals 1991–2020 and records since 1878 from the Des Moines Area threaded record (Des Moines International Airport, 25 miles north, 140 ft lower). NOAA, through RCC-ACIS.
