79° on Nov. 16, 1993, the hottest reading for this week of the year since 1893. Next is 76° in 2020.
Laurence Harbor’s center stands about 30 ft above sea level. Within three miles the land runs from 0 ft to 160 ft, a difference of 160 ft: gently rolling country. Open water lies within three miles. The highest named summit within 15 miles is Todt Hill, about 460 ft, 12 miles northeast.
Under the town center the state geologic map shows Magothy Formation (sand), from the Late Cretaceous, 84 to 87 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.
Sand. Age: Late Cretaceous, 84 to 87 million years old. About 7 mi of the line.
Silt, sand. Age: Late Cretaceous, 94 to 100 million years old. About 4 mi of the line.
Siltstone, shale. Age: Early Jurassic to Late Jurassic, 145 to 202 million years old. About 1 mi of the line.
Sand. Age: Late Cretaceous, 72 to 84 million years old. About 0.3 mi of the line.

A raindrop that lands in Laurence Harbor reaches New York Harbor and the Atlantic Ocean by way of Cheesequake Creek: about 2 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Laurence Harbor; river miles along the main stem, rounded.
Laurence Harbor has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 23° in January. A normal year brings about 29 inches of snow; with the rain, that comes to about 50 inches of water.
On November 14 Laurence Harbor normally reaches 56° and falls to 36°. The record high is 72°, in 1955; the record low 15°, in 1986. The most rain on this date, 0.81 in, fell in 1940.
