71° on Nov. 16, 1927, the hottest reading for this week of the year since 1893. Next is 70° in 1909.
Farmington’s center stands about 420 ft above sea level. Within three miles the land runs from 340 ft to 1,050 ft, a difference of 710 ft: hilly country. The highest named summit within 15 miles is Mount Blue, about 3,180 ft, 10 miles west-northwest.
Under the town center the state geologic map shows Devonian - Silurian Madrid Formation (quartzite, calc-silicate-rock), from the Silurian to Devonian, 359 to 445 million years old.
The section below crosses 13 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metasandstone, pelitic-schist, metasiltstone. Age: Early Devonian, 394 to 422 million years old. About 5 mi of the line.
Shale, sandstone. Age: Silurian, 428 to 434 million years old. About 4 mi of the line.
Schist. Age: Early Devonian, 394 to 422 million years old. About 3 mi of the line.
Metasiltstone, pelitic-schist. Age: Early Devonian, 394 to 422 million years old. About 3 mi of the line.
Metasandstone. Age: Silurian, 434 to 445 million years old. About 2 mi of the line.
Quartzite, calc-silicate-rock. Age: Silurian to Devonian, 359 to 445 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. 7 smaller units along the line are not listed.

A raindrop that lands in Farmington reaches the Atlantic Ocean by way of the Sandy and the Kennebec: about 130 river miles.
95 miles of the trip are on the Kennebec.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Farmington; river miles along the main stem, rounded.
Farmington has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 6° in January. A normal year brings about 94 inches of snow; with the rain, that comes to about 50 inches of water.
On November 14 Farmington normally reaches 45° and falls to 26°. The record high is 66°, in 1930; the record low 3°, in 2019. The most rain on this date, 2.35 in, fell in 1937.
