78° on Nov. 15, 1993, the hottest reading for this week of the year since 1871. Next is 74° in 1949.
Avalon’s center stands about 9 ft above sea level. Within three miles the land runs from 0 ft to 10 ft, a difference of 10 ft: nearly flat ground. Open water lies within three miles.
Under the town center the state geologic map shows Unnamed Formation at Cape May (sand, clay), from the Late Pliocene, 2.6 to 3.6 million years old.
The section below crosses 2 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 9 mi of the line.
Sand, clay. Age: Late Pliocene, 2.6 to 3.6 million years old. About 3 mi of the line.

Avalon has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 29° in January. A normal year brings about 15 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Avalon normally reaches 57° and falls to 41°. The record high is 74°, in 1993; the record low 20°, in 2019. The most rain on this date, 1.64 in, fell in 1995.
