Weathersfield’s center stands about 1,250 ft above sea level. Within three miles the land runs from 490 ft to 1,680 ft, a difference of 1,190 ft: steep hill country. The highest named summit within 15 miles is Ludlow Mountain, about 3,350 ft, 14 miles west.
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 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Biotite-gneiss. Age: Mesoproterozoic, 1.4 to 1.6 billion years old. About 4 mi of the line.
Paragneiss. Age: Mesoproterozoic, 1.2 to 1.2 billion years old. About 4 mi of the line.
Gneiss. Age: Mesoproterozoic, 1.2 to 1.6 billion years old. About 3 mi of the line.
Phyllite, limestone. Age: Silurian to Early Devonian, 394 to 425 million years old. About 3 mi of the line.
Syenite. Age: Early Cretaceous, 120 to 122 million years old. About 3 mi of the line.
Slate, phyllite, mica-schist. Age: Silurian to Early Devonian, 394 to 425 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 Weathersfield reaches Long Island Sound and the Atlantic Ocean by way of the Black River and the Connecticut: about 200 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Weathersfield; river miles along the main stem, rounded.
Weathersfield has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 11° in January. About 40 inches of rain fall in a normal year.
On November 14 Weathersfield normally reaches 47° and falls to 28°. The record high is 62°, in 2016; the record low 11°, in 2019. The most rain on this date, 1.12 in, fell in 2009.
