Grover’s center stands about 690 ft above sea level. Within three miles the land runs from 620 ft to 760 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Mount LeBett, about 1,000 ft, 14 miles west.
Under the town center the state geologic map shows Sinnipee Group (dolostone), from the Ordovician, 445 to 487 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 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.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 11 mi of the line.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 7 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.
Sandstone. Age: Ordovician, 445 to 487 million years old. About 1 mi of the line.

A raindrop that lands in Grover reaches Lake Michigan by way of Bundy Creek, Trout Creek and the Peshtigo: about 19 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Grover; river miles along the main stem, rounded.
Grover has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 10° in January. A normal year brings about 44 inches of snow; with the rain, that comes to about 33 inches of water.
On November 14 Grover normally reaches 44° and falls to 29°. The record high is 67°, in 1958; the record low 10°, in 1933. The most rain on this date, 0.70 in, fell in 2024.
Normals 1991–2020 and records since 1919 at Marinette, 12 miles east-northeast, 100 ft lower. NOAA, through RCC-ACIS.
