79° on Nov. 16, 1993, the hottest reading for this week of the year since 1874. Next is 78° in 1973.
Manalapan’s center stands about 160 ft above sea level. Within three miles the land runs from 80 ft to 320 ft, a difference of 240 ft: rolling country. The highest named summit within 15 miles is Beacon Hill, about 430 ft, 12 miles northeast.
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 61×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay, silt. Age: Late Cretaceous, 72 to 84 million years old. About 5 mi of the line.
Sand, clay. Age: Late Cretaceous, 72 to 84 million years old. About 3 mi of the line.
Clay, sand. Age: Early Miocene, 16 to 23 million years old. About 3 mi of the line.
Sand. Age: Early Paleocene, 62 to 66 million years old. About 3 mi of the line.
Sand. Age: Middle Miocene, 12 to 14 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. 6 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Manalapan reaches New York Harbor and the Atlantic Ocean by way of Matchaponix Brook, the South River and the Raritan: about 30 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Manalapan; river miles along the main stem, rounded.
Manalapan has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 23° in January. About 49 inches of rain fall in a normal year.
On November 14 Manalapan normally reaches 57° and falls to 36°. The record high is 76°, in 1993; the record low 20°, in 2019. The most rain on this date, 0.85 in, fell in 2008.
Normals 1991–2020 and records since 1874 at Freehold-Marlboro, 9 miles east-northeast. NOAA, through RCC-ACIS.
