89° on Nov. 17, 1978, the hottest reading for this week of the year since 1904. Next is 88° in 1989.
Hagan’s center stands about 200 ft above sea level. Within three miles the land runs from 110 ft to 220 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Pleistocene-Pliocene sands and gravels (sand, gravel), from the Pliocene to Pleistocene, less than 5.3 million years old.
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.
Sand, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 15 mi of the line.
Sandstone, claystone. Age: Tertiary Neogene, 2.6 to 23 million years old. About 10 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 Hagan reaches the Atlantic Ocean by way of Bull Creek, the Canoochee and the Ogeechee: about 100 river miles.
55 miles of the trip are on the Canoochee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hagan; river miles along the main stem, rounded.
Hagan has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 37° in January. About 50 inches of rain fall in a normal year.
On November 14 Hagan normally reaches 70° and falls to 46°. The record high is 85°, in 1916; the record low 29°, in 1906. The most rain on this date, 1.45 in, fell in 2008.
Normals 1991–2020 and records since 1904 at Glennville 3 NW, 11 miles south. NOAA, through RCC-ACIS.
