86° on Nov. 11, 1946, the hottest reading for this week of the year since 1937. Next is 85° in 1958.
Pimlico’s center stands about 20 ft above sea level. Within three miles the land runs from 0 ft to 80 ft, a difference of 80 ft: gently rolling country. Open water lies within three miles.
The section below crosses 4 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, clay. Age: Quaternary, less than 2.6 million years old. About 16 mi of the line.
Limestone, sand. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Sand, clay. Age: Quaternary, less than 2.6 million years old. About 1 mi of the line.
Peat. Age: Quaternary, less than 2.6 million years old. About 0.7 mi of the line.

A raindrop that lands in Pimlico reaches Charleston Harbor and the Atlantic Ocean by way of the West Branch Cooper and the Cooper: about 35 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pimlico; river miles along the main stem, rounded.
Pimlico has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 39° in January. About 52 inches of rain fall in a normal year.
On November 14 Pimlico normally reaches 70° and falls to 47°. The record high is 82°, in 1993; the record low 27°, in 1981. The most rain on this date, 0.57 in, fell in 1957.
Normals 1991–2020 and records since 1937 from the Charleston Area threaded record (Charleston Intl. Airport, 15 miles south-southwest). NOAA, through RCC-ACIS.
