81° on Nov. 15, 1993, the hottest reading for this week of the year since 1960. Next is 80° in 1985.
Nokesville’s center stands about 260 ft above sea level. Within three miles the land runs from 180 ft to 380 ft, a difference of 200 ft: gently rolling country. The highest named summit within 15 miles is Signal Mountain, about 1,380 ft, 15 miles north-northwest.
Under the town center the state geologic map shows Newark Supergroup; Triassic shale and siltstone (shale, siltstone), from the Triassic, 202 to 252 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 30×. 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, siltstone. Age: Triassic, 202 to 252 million years old. About 6 mi of the line.
Sandstone. Age: Triassic, 202 to 252 million years old. About 3 mi of the line.
Metasandstone. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Age: Cambrian to Ordovician, 445 to 542 million years old. About 2 mi of the line.
Shale, sandstone, siltstone. Age: Triassic, 202 to 252 million years old. About 2 mi of the line.
Basalt. Age: Early Jurassic, 175 to 202 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. 6 smaller units along the line are not listed.

A raindrop that lands in Nokesville reaches Chesapeake Bay and the Atlantic Ocean by way of Slate Run, Cedar Run, the Occoquan and the Potomac: about 120 river miles.
85 miles of the trip are on the Potomac.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Nokesville; river miles along the main stem, rounded.
Nokesville has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 25° in January. A normal year brings about 21 inches of snow; with the rain, that comes to about 43 inches of water.
On November 14 Nokesville normally reaches 57° and falls to 36°. The record high is 80°, in 1985; the record low 13°, in 1986. The most rain on this date, 1.90 in, fell in 1972.
