78° on Nov. 16, 1993, the hottest reading for this week of the year since 1931. Next is 76° in 1973.
Short Hills’s center stands about 290 ft above sea level. Within three miles the land runs from 100 ft to 610 ft, a difference of 510 ft: hilly country. The highest named summit within 15 miles is Calais Mountain, about 1,120 ft, 15 miles west-northwest.
Under the town center the state geologic map shows Preakness Basalt, from the Early Jurassic, 175 to 202 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 29×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, siltstone, mudstone. Age: Early Jurassic, 175 to 202 million years old. About 8 mi of the line.
Sandstone-mudstone, siltstone-mudstone. Age: Early Jurassic to Late Jurassic, 145 to 202 million years old. About 5 mi of the line.
Sandstone, siltstone. Age: Early Jurassic to Late Jurassic, 145 to 202 million years old. About 2 mi of the line.
Siltstone, shale. Age: Early Jurassic to Late Jurassic, 145 to 202 million years old. About 2 mi of the line.
Basalt. Age: Early Jurassic, 175 to 202 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. 6 smaller units along the line are not listed.

A raindrop that lands in Short Hills reaches New York Harbor and the Atlantic Ocean by way of Taylor Brook, Canoe Brook and the Passaic: about 60 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Short Hills; river miles along the main stem, rounded.
Short Hills has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 22° in January. A normal year brings about 24 inches of snow; with the rain, that comes to about 50 inches of water.
On November 14 Short Hills normally reaches 55° and falls to 35°. The record high is 71°, in 1964; the record low 11°, in 1986. The most rain on this date, 1.51 in, fell in 1937.
