82° on Nov. 15, 1993, the hottest reading for this week of the year since 1915. Next is 79° in 1973.
Richboro’s center stands about 270 ft above sea level. Within three miles the land runs from 90 ft to 370 ft, a difference of 280 ft: rolling country. The highest named summit within 15 miles is Buckingham Mountain, about 570 ft, 7 miles north-northwest.
Under the town center the state geologic map shows Stockton Formation (arkose), from the Triassic, 202 to 252 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 34×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Arkose. Age: Triassic, 202 to 252 million years old. About 10 mi of the line.
Sand. Age: Miocene, 5.3 to 23 million years old. About 3 mi of the line.
Gneiss. Age: Precambrian. About 2 mi of the line.
Argillite. Age: Triassic, 202 to 252 million years old. About 2 mi of the line.
Mudstone. Age: Triassic, 202 to 252 million years old. About 2 mi of the line.
Mica-schist. Age: Paleozoic, 252 to 542 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 6 smaller units along the line are not listed.

A raindrop that lands in Richboro reaches Delaware Bay and the Atlantic Ocean by way of Neshaminy Creek and the Delaware: about 100 river miles.
85 miles of the trip are on the Delaware.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Richboro; river miles along the main stem, rounded.
Richboro has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 22° in January. A normal year brings about 20 inches of snow; with the rain, that comes to about 51 inches of water.
On November 14 Richboro normally reaches 55° and falls to 33°. The record high is 76°, in 1973; the record low 17°, in 1920. The most rain on this date, 2.23 in, fell in 1972.
Normals 1991–2020 and records since 1915 at Neshaminy Falls, 6 miles south-southeast, 230 ft lower. NOAA, through RCC-ACIS.
