13° on Nov. 16, 1996, the coldest reading for this week of the year since 1892. Next is 14° in 1933.
Boonton’s center stands about 410 ft above sea level. Within three miles the land runs from 190 ft to 840 ft, a difference of 650 ft: hilly country. The highest named summit within 15 miles is Bowling Green Mountain, about 1,420 ft, 10 miles northwest.
The section below crosses 15 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 16×. 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 4 mi of the line.
Sandstone, siltstone-mudstone. Age: Early Jurassic, 175 to 202 million years old. About 3 mi of the line.
Granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Granite. Age: Mesoproterozoic, 1.1 to 1.1 billion years old. About 2 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.

A raindrop that lands in Boonton reaches New York Harbor and the Atlantic Ocean by way of the Rockaway and the Passaic: about 55 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Boonton; river miles along the main stem, rounded.
Boonton has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 21° in January. About 49 inches of rain fall in a normal year.
On November 14 Boonton normally reaches 53° and falls to 33°. The record high is 80°, in 1931; the record low 19°, in 2019. The most rain on this date, 2.10 in, fell in 1937.
