Fox Lake’s center stands about 760 ft above sea level. Within three miles the land runs from 730 ft to 880 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Gander Mountain, about 960 ft, 5 miles north.
Under the town center the state geologic map shows Silurian System undivided (dolostone, limestone), from the Silurian, 422 to 445 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, limestone. Age: Silurian, 422 to 445 million years old. About 16 mi of the line.
Dolostone. Age: Silurian, 422 to 445 million years old. About 4 mi of the line.
Shale, dolostone. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 454 million years old. About 0.8 mi of the line.

A raindrop that lands in Fox Lake reaches the Gulf of America by way of Fox Lake, the Fox River, the Illinois and the Mississippi: about 1,540 river miles.
Lakes on the way: Peoria Lake and Fox Lake.
1,190 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fox Lake; river miles along the main stem, rounded.
Fox Lake has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 13° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 Fox Lake normally reaches 49° and falls to 30°. The record high is 70°, in 1999; the record low 10°, in 1996. The most rain on this date, 0.59 in, fell in 2024.
Normals 1991–2020 and records since 1948 at Mchenry Stratton Lock/Dam, 9 miles south-southwest. NOAA, through RCC-ACIS.
