35° on Nov. 17, 2007, the coldest reading for this week of the year since 1995. Next is 36° in 1997.
Apalachicola’s center stands about 17 ft above sea level. Within three miles the land runs from 0 ft to 50 ft, a difference of 50 ft: nearly flat ground. Open water lies within three miles.
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.
Clay, sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 11 mi of the line.
Sand, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.6 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 0.5 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 Apalachicola reaches the Gulf of America by way of Scipio Creek and the Apalachicola: about 1 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Apalachicola; river miles along the main stem, rounded.
Apalachicola has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 44° in January. About 58 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1995 at Apalachicola Airport, 2 miles west. NOAA, through RCC-ACIS.
