81° on Nov. 15, 1993, the hottest reading for this week of the year since 1945. Next is 77° in 2006.
Eddington’s center stands about 80 ft above sea level. Within three miles the land runs from 0 ft to 140 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Camp Hill, about 360 ft, 14 miles west-northwest.
Under the town center the state geologic map shows Pensauken and Bridgeton Formations, undifferentiated (sand), from the Miocene, 5.3 to 23 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 49×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mica-schist. Age: Paleozoic, 252 to 542 million years old. About 8 mi of the line.
Sand. Age: Miocene, 5.3 to 23 million years old. About 4 mi of the line.
Sand, clay. Age: Pleistocene, less than 2.6 million years old. About 4 mi of the line.
Clay, silt. Age: Late Cretaceous, 72 to 84 million years old. About 3 mi of the line.
Sand. Age: Late Cretaceous, 84 to 87 million years old. About 2 mi of the line.
Sand, clay. Age: Late Cretaceous, 94 to 100 million years old. About 1 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.
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 Eddington reaches Delaware Bay and the Atlantic Ocean by way of Poquessing Creek and the Delaware: about 85 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Eddington; river miles along the main stem, rounded.
Eddington has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 27° in January. About 45 inches of rain fall in a normal year.
On November 14 Eddington normally reaches 57° and falls to 39°. The record high is 74°, in 1993; the record low 20°, in 1986. The most rain on this date, 2.30 in, fell in 1972.
Normals 1991–2020 and records since 1945 at Northeast Philadelphia Airport, 4 miles west. NOAA, through RCC-ACIS.
