71° on Nov. 16, 1927, the hottest reading for this week of the year since 1893. Next is 70° in 1909.
Jay’s center stands about 390 ft above sea level. Within three miles the land runs from 330 ft to 950 ft, a difference of 620 ft: hilly country. The highest named summit within 15 miles is Saddleback Mountain, about 2,540 ft, 11 miles northwest.
Under the town center the state geologic map shows Silurian Sangerville Formation, Anasagunticook member (metasandstone), from the Silurian, 434 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 12×. 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. Age: Silurian, 428 to 434 million years old. About 5 mi of the line.
Metasandstone. Age: Silurian, 434 to 445 million years old. About 4 mi of the line.
Metasiltstone, pelitic-schist. Age: Early Devonian, 394 to 422 million years old. About 4 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 2 mi of the line.
Metasandstone, pelitic-schist, metasiltstone. Age: Early Devonian, 394 to 422 million years old. About 2 mi of the line.
Granite. Age: Devonian, 359 to 422 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 Jay reaches the Atlantic Ocean by way of Mosquito Brook, the Androscoggin and the Kennebec: about 85 river miles.
65 miles of the trip are on the Androscoggin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Jay; river miles along the main stem, rounded.
Jay 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 Jay 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.
Normals 1991–2020 and records since 1893 at Farmington, 14 miles north. NOAA, through RCC-ACIS.
