South Windsor’s center stands about 50 ft above sea level. Within three miles the land runs from 0 ft to 170 ft, a difference of 170 ft: gently rolling country. The highest named summit within 15 miles is Soapstone Mountain, about 1,090 ft, 14 miles northeast.
Under the town center the state geologic map shows Portland Arkose (arkose, siltstone), from the Early Jurassic, 175 to 202 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 20×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Arkose, siltstone. Age: Early Jurassic, 175 to 202 million years old. About 14 mi of the line.
Arkose. Age: Late Triassic to Early Jurassic, 175 to 237 million years old. About 3 mi of the line.
Gneiss. Age: Middle Ordovician, 459 to 471 million years old. About 2 mi of the line.
Schist, quartzite. Age: Devonian, 359 to 422 million years old. About 1 mi of the line.
Schist, gneiss. Age: Cambrian to Ordovician, 445 to 542 million years old. About 1 mi of the line.
Basalt, gabbro. Age: Early Jurassic, 175 to 202 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in South Windsor reaches Long Island Sound and the Atlantic Ocean by way of Bancroft Brook and the Connecticut: about 60 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of South Windsor; river miles along the main stem, rounded.
South Windsor has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 19° in January. A normal year brings about 52 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 South Windsor normally reaches 52° and falls to 33°. The record high is 74°, in 1973; the record low 15°, in 2019. The most rain on this date, 1.87 in, fell in 1972.
Normals 1991–2020 and records since 1905 from the Hartford Area threaded record (Hartford-Bradley International Airport, 8 miles north-northwest, 120 ft higher). NOAA, through RCC-ACIS.
