20° on Nov. 14, 1963, the coldest reading for this week of the year since 1913. Next is 25° in 1969.
Perdido’s center stands about 240 ft above sea level. Within three miles the land runs from 170 ft to 300 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Miocene Series undifferentiated (sand, clay), from the Miocene to Pliocene, 2.6 to 23 million years old.
The section below crosses 3 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 to Pliocene, 2.6 to 23 million years old. About 12 mi of the line.
Sand. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 10 mi of the line.
Sand. Age: Holocene, less than 12,000 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.

A raindrop that lands in Perdido reaches Perdido Bay and the Gulf of America by way of Bushy Creek, Dyas Creek and the Perdido: about 60 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Perdido; river miles along the main stem, rounded.
Perdido has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 41° in January. About 72 inches of rain fall in a normal year.
On November 14 Perdido normally reaches 70° and falls to 49°. The record high is 85°, in 1955; the record low 20°, in 1963. The most rain on this date, 5.70 in, fell in 1961.
Normals 1991–2020 and records since 1913 at Bay Minette, 12 miles southwest. NOAA, through RCC-ACIS.
