Monroe Manor’s center stands about 120 ft above sea level. Within three miles the land runs from 90 ft to 290 ft, a difference of 200 ft: gently rolling country. The highest named summit within 15 miles is Rocky Hill, about 480 ft, 15 miles west-northwest.
Under the town center the state geologic map shows Englishtown Formation (sand, clay), from the Late Cretaceous, 72 to 84 million years old.
The section below crosses 14 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 63×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Late Cretaceous, 66 to 72 million years old. About 4 mi of the line.
Sand. Age: Late Cretaceous, 84 to 87 million years old. About 4 mi of the line.
Sand. Age: Middle Miocene, 12 to 14 million years old. About 3 mi of the line.
Sand, clay. Age: Late Cretaceous, 72 to 84 million years old. About 3 mi of the line.
Silt, sand. Age: Late Cretaceous, 94 to 100 million years old. About 2 mi of the line.
Sand. Age: Late Cretaceous, 72 to 84 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 8 smaller units along the line are not listed.

A raindrop that lands in Monroe Manor reaches New York Harbor and the Atlantic Ocean by way of the Millstone and the Raritan: about 55 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Monroe Manor; river miles along the main stem, rounded.
Monroe Manor has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 21° in January. A normal year brings about 24 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Monroe Manor normally reaches 56° and falls to 33°. The record high is 72°, in 1959; the record low 15°, in 2019. The most rain on this date, 1.89 in, fell in 1972.
