Northampton’s center stands about 2,370 ft above sea level. Within three miles the land runs from 1,660 ft to 2,660 ft, a difference of 1,000 ft: steep hill country. The highest named summit within 15 miles is Sampson Rock, about 2,940 ft, 10 miles south-southwest.
Under the town center the state geologic map shows Foreknobs Formation (sandstone), from the Late Devonian, 359 to 384 million years old.
The section below crosses 14 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Northampton reaches Chesapeake Bay and the Atlantic Ocean by way of Wills Creek, the North Branch Potomac and the Potomac: about 340 river miles.
290 miles of the trip are on the Potomac.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Northampton; river miles along the main stem, rounded.
Northampton has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 19° in January. A normal year brings about 72 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Northampton normally reaches 49° and falls to 32°. The record high is 64°, in 2005; the record low 8°, in 1986. The most rain on this date, 0.69 in, fell in 1972.
Normals 1991–2020 and records since 1972 at Frostburg 2, 13 miles south-southwest, 200 ft lower. NOAA, through RCC-ACIS.
