4.30 inches of rain fell in two days, the most for this week of the year since records began in 1948. The next wettest, 2.57 inches, fell in 2009.
Elon’s center stands about 720 ft above sea level. Within three miles the land runs from 610 ft to 740 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Cane Creek Mountains, about 1,020 ft, 11 miles south-southeast.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 46×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metagabbro, metadiorite. Age: Neoproterozoic to Paleozoic, 252 to 1,000 million years old. About 8 mi of the line.
Metabasalt. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 6 mi of the line.
Metagranite. Age: Neoproterozoic to Middle Cambrian, 520 to 650 million years old. About 5 mi of the line.
Metadacite, metarhyolite, metavolcanic. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 4 mi of the line.
Metaandesite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 0.4 mi of the line.
Granitic. Age: Late Mississippian to Permian, 265 to 325 million years old. About 0.3 mi of the line.

A raindrop that lands in Elon reaches the Atlantic Ocean by way of Travis Creek, the Haw and the Cape Fear: about 250 river miles.
190 miles of the trip are on the Cape Fear.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Elon; river miles along the main stem, rounded.
Elon has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 30° in January. About 46 inches of rain fall in a normal year.
On November 14 Elon normally reaches 61° and falls to 39°. The record high is 79°, in 1955; the record low 23°, in 2019. The most rain on this date, 1.57 in, fell in 2024.
Normals 1991–2020 and records since 1948 at Greensboro Wtp, 17 miles west. NOAA, through RCC-ACIS.
