78° on Nov. 15, 1993, the hottest reading for this week of the year since 1858. Next is 74° in 1902.
Flying Hills’s center stands about 420 ft above sea level. Within three miles the land runs from 170 ft to 840 ft, a difference of 670 ft: hilly country. The highest named summit within 15 miles is Eagle Peak, about 1,320 ft, 15 miles west-northwest.
Under the town center the state geologic map shows Hammer Creek conglomerate (conglomerate, sandstone), from the Triassic, 202 to 252 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 24×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mudstone. Age: Triassic, 202 to 252 million years old. About 9 mi of the line.
Conglomerate, sandstone. Age: Triassic, 202 to 252 million years old. About 7 mi of the line.
Sandstone. Age: Triassic, 202 to 252 million years old. About 5 mi of the line.
Basalt. Age: Jurassic, 145 to 202 million years old. About 3 mi of the line.

A raindrop that lands in Flying Hills reaches Delaware Bay and the Atlantic Ocean by way of the Schuylkill and the Delaware: about 130 river miles.
70 miles of the trip are on the Schuylkill.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Flying Hills; river miles along the main stem, rounded.
Flying Hills has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 23° in January. About 45 inches of rain fall in a normal year.
On November 14 Flying Hills normally reaches 54° and falls to 36°. The record high is 74°, in 1955; the record low 16°, in 1986. The most rain on this date, 1.37 in, fell in 1995.
