81° on Nov. 15, 1993, the hottest reading for this week of the year since 1864. Next is 78° in 1990.
Shamong’s center stands about 90 ft above sea level. Within three miles the land runs from 50 ft to 160 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Cohansey Formation (sand), from the Middle Miocene, 12 to 14 million years old.
The section below crosses 6 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: Middle Miocene, 12 to 14 million years old. About 19 mi of the line.
Clay, sand. Age: Early Miocene, 16 to 23 million years old. About 2 mi of the line.
Sand. Age: Middle Paleocene, 59 to 62 million years old. About 1 mi of the line.
Sand, marl. Age: Early Eocene, 48 to 56 million years old. About 0.9 mi of the line.
Sand. Age: Late Cretaceous, 66 to 72 million years old. About 0.5 mi of the line.
Sand. Age: Early Paleocene, 62 to 66 million years old. About 0.3 mi of the line.

A raindrop that lands in Shamong reaches the Atlantic Ocean by way of Bard Branch, Springers Brook, the Batsto and the Mullica: about 30 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Shamong; river miles along the main stem, rounded.
Shamong has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 26° in January. About 49 inches of rain fall in a normal year.
On November 14 Shamong normally reaches 57° and falls to 38°. The record high is 75°, in 1993; the record low 18°, in 1986. The most rain on this date, 0.93 in, fell in 1972.
Normals 1991–2020 and records since 1864 at Moorestown 4 E, 15 miles north-northwest. NOAA, through RCC-ACIS.
