80° on Nov. 15, 1993, the hottest reading for this week of the year since 1894. Next is 78° in 1973.
Chesapeake City’s center stands about 6 ft above sea level. Within three miles the land runs from 0 ft to 150 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Egg Hill, about 450 ft, 10 miles north-northwest.
The section below crosses 7 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, 66 to 100 million years old. About 5 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 4 mi of the line.
Gravel, sand. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Sand. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
Silt, sand. Age: Cretaceous, 66 to 145 million years old. About 2 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 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. 1 smaller unit 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 Chesapeake City reaches Chesapeake Bay and the Atlantic Ocean by way of Back Creek and the Elk River: about 14 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Chesapeake City; river miles along the main stem, rounded.
Chesapeake City has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 26° in January. A normal year brings about 20 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Chesapeake City normally reaches 56° and falls to 38°. The record high is 76°, in 1955; the record low 20°, in 1986. The most rain on this date, 2.42 in, fell in 1972.
Normals 1991–2020 and records since 1894 from the Wilmington Area threaded record (Wilmington Airport, 15 miles northeast). NOAA, through RCC-ACIS.
