85° on Nov. 11, 1994, the hottest reading for this week of the year since 1957. Next is 83° in 1958.
Darien’s center stands about 40 ft above sea level. Within three miles the land runs from 0 ft to 70 ft, a difference of 70 ft: gently rolling country. Open water lies within three miles.
The section below crosses 2 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.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 12 mi of the line.
Fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 Darien reaches the Atlantic Ocean by way of the Altamaha: about 7 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Darien; river miles along the main stem, rounded.
Darien has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 42° in January. About 50 inches of rain fall in a normal year.
On November 14 Darien normally reaches 71° and falls to 52°. The record high is 80°, in 1989; the record low 33°, in 1968. The most rain on this date, 0.29 in, fell in 1972.
Normals 1991–2020 and records since 1957 at Sapelo Island, 9 miles east-northeast. NOAA, through RCC-ACIS.
