77° on Nov. 12, 1909, the hottest reading for this week of the year since 1898. Next is 76° in 1973.
Lamington’s center stands about 150 ft above sea level. Within three miles the land runs from 90 ft to 380 ft, a difference of 290 ft: rolling country. The highest named summit within 15 miles is Upper Pohatcong Mountain, about 1,270 ft, 15 miles north-northwest.
Under the town center the state geologic map shows Passaic Formation (siltstone, shale), from the Early Jurassic to Late Jurassic, 145 to 202 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 17×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, shale. Age: Early Jurassic to Late Jurassic, 145 to 202 million years old. About 14 mi of the line.
Dolostone. Age: Early Cambrian to Middle Cambrian, 497 to 542 million years old. About 2 mi of the line.
Biotite-gneiss. 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 1 mi of the line.
Granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 1 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 5 smaller units along the line are not listed.

A raindrop that lands in Lamington reaches New York Harbor and the Atlantic Ocean by way of the Lamington and the Raritan: about 45 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lamington; river miles along the main stem, rounded.
Lamington has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 21° in January. A normal year brings about 27 inches of snow; with the rain, that comes to about 51 inches of water.
On November 14 Lamington normally reaches 54° and falls to 34°. The record high is 72°, in 1964; the record low 15°, in 1986. The most rain on this date, 0.94 in, fell in 1940.
Normals 1991–2020 and records since 1898 at Flemington 5 NNW, 11 miles southwest, 120 ft higher. NOAA, through RCC-ACIS.
