Stratford’s center stands about 930 ft above sea level. Within three miles the land runs from 850 ft to 1,860 ft, a difference of 1,010 ft: steep hill country. The highest named summit within 15 miles is Mount Cabot, about 4,150 ft, 12 miles southeast.
The section below crosses 7 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, metasiltstone, phyllite. Age: Middle Cambrian to Early Ordovician, 485 to 500 million years old. About 9 mi of the line.
Metasedimentary, metavolcanic. Age: Silurian, 422 to 445 million years old. About 4 mi of the line.
Granite. Age: Middle Jurassic to Late Jurassic, 145 to 175 million years old. About 4 mi of the line.
Granite. Age: Late Ordovician to Silurian, 438 to 446 million years old. About 3 mi of the line.
Metaclastic. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Syenite. Age: Jurassic, 145 to 202 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Stratford reaches Long Island Sound and the Atlantic Ocean by way of Bog Brook and the Connecticut: about 340 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Stratford; river miles along the main stem, rounded.
Stratford has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 0° in January. A normal year brings about 81 inches of snow; with the rain, that comes to about 41 inches of water.
On November 14 Stratford normally reaches 42° and falls to 22°. The record high is 64°, in 1989; the record low −6°, in 2019. The most rain on this date, 0.60 in, fell in 1975.
Normals 1991–2020 and records since 1960 at Colebrook 3 SW, 14 miles north, 190 ft higher. NOAA, through RCC-ACIS.
