Barrington Hills’s center stands about 860 ft above sea level. Within three miles the land runs from 770 ft to 910 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Maquoketa Formation or Group (shale, limestone), from the Late Ordovician, 445 to 454 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 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, limestone. Age: Silurian, 422 to 445 million years old. About 14 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 454 million years old. About 10 mi of the line.

A raindrop that lands in Barrington Hills reaches the Gulf of America by way of Spring Creek, the Fox River, the Illinois and the Mississippi: about 1,520 river miles.
Lake on the way: Peoria Lake.
1,190 miles of the trip are on the Mississippi.

Barrington Hills has a hot-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 13° in January. A normal year brings about 38 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Barrington Hills normally reaches 47° and falls to 31°. The record high is 72°, in 1989; the record low 5°, in 1986. The most rain on this date, 0.54 in, fell in 2024.
