72° on Nov. 11, 2020, the hottest reading for this week of the year since 1958. Next is 71° in 2012.
East Side’s center stands about 1,270 ft above sea level. Within three miles the land runs from 1,090 ft to 1,690 ft, a difference of 600 ft: hilly country. The highest named summit within 15 miles is Big Pine Hill, about 2,260 ft, 14 miles north-northeast.
Under the town center the state geologic map shows Mauch Chunk Formation (shale, siltstone, sandstone), from the Carboniferous, 324 to 359 million years old.
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 15×. 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. Age: Carboniferous, 324 to 359 million years old. About 8 mi of the line.
Shale, siltstone, sandstone. Age: Carboniferous, 324 to 359 million years old. About 7 mi of the line.
Sandstone, siltstone. Age: Late Devonian, 359 to 384 million years old. About 4 mi of the line.
Sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 4 mi of the line.
Conglomerate-sandstone, clastic. Age: Late Devonian, 359 to 384 million years old. About 0.8 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.3 mi of the line.

A raindrop that lands in East Side reaches Delaware Bay and the Atlantic Ocean by way of the Lehigh and the Delaware: about 220 river miles.
150 miles of the trip are on the Delaware.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of East Side; river miles along the main stem, rounded.
East Side has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 16° in January. About 49 inches of rain fall in a normal year.
On November 14 East Side normally reaches 48° and falls to 30°. The record high is 65°, in 1964; the record low 10°, in 1997. The most rain on this date, 0.91 in, fell in 1972.
Normals 1991–2020 and records since 1958 at Francis E Walter Dam, 4 miles north-northeast, 240 ft higher. NOAA, through RCC-ACIS.
