73° on Nov. 16, 1993, the hottest reading for this week of the year since 1962. Next is 73° in 2020.
Monson Center’s center stands about 730 ft above sea level. Within three miles the land runs from 340 ft to 1,140 ft, a difference of 800 ft: hilly country. The highest named summit within 15 miles is Burley Hill, about 1,320 ft, 7 miles southeast.
Under the town center the state geologic map shows Partridge Formation (includes Brimfield Schist of Emerson, 1917) (mica-schist), from the Late Ordovician, 449 to 453 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 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.
Mica-schist. Age: Late Ordovician, 449 to 453 million years old. About 8 mi of the line.
Conglomerate, arkose. Age: Early Jurassic, 175 to 202 million years old. About 5 mi of the line.
Gneiss. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Schist, phyllite. Age: Early Devonian, 394 to 422 million years old. About 2 mi of the line.
Gneiss, amphibolite. Age: Late Ordovician to Silurian, 440 to 454 million years old. About 2 mi of the line.
Granofels, schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 2 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 Monson Center reaches Long Island Sound and the Atlantic Ocean by way of Chicopee Brook, the Quaboag, the Chicopee and the Connecticut: about 110 river miles.
80 miles of the trip are on the Connecticut.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Monson Center; river miles along the main stem, rounded.
Monson Center has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 16° in January. A normal year brings about 64 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Monson Center normally reaches 51° and falls to 32°. The record high is 69°, in 2010; the record low 12°, in 1986. The most rain on this date, 0.97 in, fell in 2018.
Normals 1991–2020 and records since 1962 at East Brimfield Lake, 9 miles east. NOAA, through RCC-ACIS.
