76° on Nov. 11, 2020, the hottest reading for this week of the year since 1893. Next is 74° in 1902.
Spencer’s center stands about 1,010 ft above sea level. Within three miles the land runs from 970 ft to 1,690 ft, a difference of 720 ft: hilly country. The highest named summit within 15 miles is Connecticut Hill, about 2,140 ft, 15 miles northwest.
Under the town center the state geologic map shows Upper Walton Formation (shale, sandstone, conglomerate), from the Late Devonian, 359 to 384 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 18×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, sandstone, conglomerate. Age: Late Devonian, 359 to 384 million years old. About 10 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 7 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 6 mi of the line.
Shale, siltstone. Age: Late Devonian, 359 to 384 million years old. About 0.9 mi of the line.

A raindrop that lands in Spencer reaches Chesapeake Bay and the Atlantic Ocean by way of Catatonk Creek, Owego Creek and the Susquehanna: about 340 river miles.
Lake on the way: Lake Aldred.
270 miles of the trip are on the Susquehanna.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Spencer; river miles along the main stem, rounded.
Spencer has a warm-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 16° in January. About 37 inches of rain fall in a normal year.
On November 14 Spencer normally reaches 50° and falls to 30°. The record high is 74°, in 1902; the record low 7°, in 1905. The most rain on this date, 0.94 in, fell in 1997.
Normals 1991–2020 and records since 1893 at Waverly, 15 miles south, 210 ft lower. NOAA, through RCC-ACIS.
