Elm Grove’s center stands about 750 ft above sea level. Within three miles the land runs from 690 ft to 930 ft, a difference of 240 ft: rolling country.
Under the town center the state geologic map shows Silurian, undivided (dolostone), from the Silurian, 422 to 445 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 39×. 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: Silurian, 422 to 445 million years old. About 21 mi of the line.
Limestone, shale. Age: Middle Devonian, 384 to 394 million years old. About 0.9 mi of the line.

A raindrop that lands in Elm Grove reaches Lake Michigan by way of Underwood Creek, the Menomonee, the Milwaukee and the Kinnickinnic: about 14 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 Elm Grove; river miles along the main stem, rounded.
Elm Grove has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 15° in January. A normal year brings about 52 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Elm Grove normally reaches 48° and falls to 31°. The record high is 71°, in 1971; the record low 12°, in 1959. The most rain on this date, 1.02 in, fell in 1957.
Normals 1991–2020 and records since 1948 at West Allis, 4 miles southeast. NOAA, through RCC-ACIS.
