74° on Nov. 13, 2012, the hottest reading for this week of the year since 1985. Next is 72° in 2002.
Windham’s center stands about 1,540 ft above sea level. Within three miles the land runs from 1,460 ft to 2,890 ft, a difference of 1,430 ft: steep hill country. The highest named summit within 15 miles is Hunter Mountain, about 4,040 ft, 9 miles south.
Under the town center the state geologic map shows Oneonta Formation (shale), from the Middle Devonian to Late Devonian, 359 to 394 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 6×. 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. Age: Middle Devonian to Late Devonian, 359 to 394 million years old. About 13 mi of the line.
Shale, sandstone. Age: Middle Devonian, 384 to 394 million years old. About 5 mi of the line.
Sandstone, conglomerate, shale. Age: Late Devonian, 359 to 384 million years old. About 4 mi of the line.
Sandstone, shale. Age: Middle Devonian, 384 to 388 million years old. About 1 mi of the line.
Shale, sandstone, conglomerate. Age: Late Devonian, 359 to 384 million years old. About 0.7 mi of the line.

A raindrop that lands in Windham reaches New York Harbor and the Atlantic Ocean by way of Batavia Kill, Schoharie Creek, the Mohawk and the Hudson: about 280 river miles.
160 miles of the trip are on the Hudson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Windham; river miles along the main stem, rounded.
Windham has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 11° in January. About 45 inches of rain fall in a normal year.
On November 14 Windham normally reaches 50° and falls to 28°. The record high is 65°, in 2011; the record low 8°, in 2019. The most rain on this date, 0.90 in, fell in 1997.
Normals 1991–2020 and records since 1985 at Lansing Manor, 15 miles northwest, 430 ft lower. NOAA, through RCC-ACIS.
