76° on Nov. 11, 2022, the hottest reading for this week of the year since 1928. Next is 74° in 2020.
Fairgrove’s center stands about 660 ft above sea level. Within three miles the land runs from 610 ft to 690 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Saginaw Formation (sandstone, shale), from the Carboniferous, 299 to 324 million years old.
The section below crosses 3 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.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 18 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

Fairgrove has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 15° in January. A normal year brings about 42 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Fairgrove normally reaches 47° and falls to 31°. The record high is 67°, in 2009; the record low 9°, in 1986. The most rain on this date, 1.10 in, fell in 1959.
Normals 1991–2020 and records since 1928 at Caro Wwtp, 8 miles east-southeast. NOAA, through RCC-ACIS.
