81° on Nov. 15, 1993, the hottest reading for this week of the year since 1894. Next is 78° in 1902.
North Beach’s center stands about 20 ft above sea level. Within three miles the land runs from 0 ft to 210 ft, a difference of 210 ft: rolling country. Open water lies within three miles.
Under the town center the state geologic map shows Lowland Deposits (fine-detrital, coarse-detrital), from the Pleistocene, less than 2.6 million years old.
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: Miocene, 5.3 to 23 million years old. About 7 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Sand, silt. Age: Miocene, 5.3 to 23 million years old. About 2 mi of the line.
Gravel, sand. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.

Rain that falls on North Beach runs straight into Chesapeake Bay and the Atlantic Ocean.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of North Beach; river miles along the main stem, rounded.
North Beach has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 30° in January. About 44 inches of rain fall in a normal year.
On November 14 North Beach normally reaches 57° and falls to 43°. The record high is 78°, in 1993; the record low 18°, in 1986. The most rain on this date, 1.96 in, fell in 1972.
