78° on Nov. 15, 1993, the hottest reading for this week of the year since 1905. Next is 74° in 1909.
Windsor’s center stands about 50 ft above sea level. Within three miles the land runs from 0 ft to 200 ft, a difference of 200 ft: gently rolling country. The highest named summit within 15 miles is Pine Cone, about 1,100 ft, 13 miles west-northwest.
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 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 23×. 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 17 mi of the line.
Arkose. Age: Late Triassic to Early Jurassic, 175 to 237 million years old. About 3 mi of the line.
Basalt, gabbro. Age: Early Jurassic, 175 to 202 million years old. About 1 mi of the line.
Gneiss, granofels. Age: Middle Ordovician, 459 to 471 million years old. About 0.8 mi of the line.
Siltstone, shale. Age: Early Jurassic, 175 to 202 million years old. About 0.7 mi of the line.
Gneiss. Age: Middle Ordovician, 459 to 471 million years old. About 0.5 mi of the line.

A raindrop that lands in Windsor reaches Long Island Sound and the Atlantic Ocean by way of the Farmington and the Connecticut: about 60 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Windsor; river miles along the main stem, rounded.
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 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, 6 miles north-northwest, 120 ft higher). NOAA, through RCC-ACIS.
