19° on Nov. 11, 2017, the coldest reading for this week of the year since 1934. Next is 19° in 2019.
Kempton’s center stands about 410 ft above sea level. Within three miles the land runs from 410 ft to 1,020 ft, a difference of 610 ft: hilly country. The highest named summit within 15 miles is Dans Pulpit, about 1,660 ft, 5 miles west-northwest.
Under the town center the state geologic map shows Shale and graywacke of Hamburg sequence, from the Ordovician, 445 to 487 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 16×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, conglomerate. Age: Silurian, 422 to 445 million years old. About 9 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 7 mi of the line.
Shale, slate. Age: Ordovician, 445 to 487 million years old. About 5 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.

A raindrop that lands in Kempton reaches Delaware Bay and the Atlantic Ocean by way of Ontelaunee Creek, Maiden Creek, the Schuylkill and the Delaware: about 170 river miles.
85 miles of the trip are on the Schuylkill.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Kempton; river miles along the main stem, rounded.
Kempton has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 19° in January. A normal year brings about 27 inches of snow; with the rain, that comes to about 52 inches of water.
Normals 1991–2020 and records since 1934 at Lehighton 1 SSW, 16 miles north-northeast. NOAA, through RCC-ACIS.
