74° on Nov. 15, 1993, the hottest reading for this week of the year since 1874. Next is 73° in 1928.
Duanesburg’s center stands about 710 ft above sea level. Within three miles the land runs from 550 ft to 1,410 ft, a difference of 860 ft: hilly country. The highest named summit within 15 miles is Cannady Hill, about 2,150 ft, 12 miles south-southwest.
Under the town center the state geologic map shows Schenectady Formation (graywacke, sandstone, siltstone), from the Late Ordovician, 445 to 459 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 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Graywacke, sandstone, siltstone. Age: Late Ordovician, 445 to 459 million years old. About 17 mi of the line.
Sandstone, shale. Age: Middle Devonian, 384 to 394 million years old. About 3 mi of the line.
Limestone, dolostone. Age: Early Devonian, 394 to 422 million years old. About 2 mi of the line.
Shale. Age: Early Devonian to Middle Devonian, 388 to 410 million years old. About 2 mi of the line.
Sandstone. Age: Early Devonian, 394 to 422 million years old. About 1 mi of the line.

A raindrop that lands in Duanesburg reaches New York Harbor and the Atlantic Ocean by way of Normans Kill and the Hudson: about 180 river miles.
140 miles of the trip are on the Hudson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Duanesburg; river miles along the main stem, rounded.
Duanesburg has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 16° in January. A normal year brings about 59 inches of snow; with the rain, that comes to about 41 inches of water.
On November 14 Duanesburg normally reaches 50° and falls to 32°. The record high is 70°, in 1973; the record low 12°, in 1996. The most rain on this date, 1.79 in, fell in 1972.
