74° on Nov. 15, 1993, the hottest reading for this week of the year since 1957. Next is 72° in 1964.
Hudson’s center stands about 100 ft above sea level. Within three miles the land runs from 0 ft to 390 ft, a difference of 390 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Stoppel Point, about 3,430 ft, 14 miles west.
Under the town center the state geologic map shows Glacial and Alluvial Deposits (unconsolidated), from the Quaternary, less than 2.6 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 16×. 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, sandstone. Age: Middle Devonian, 384 to 394 million years old. About 5 mi of the line.
Shale. Age: Cambrian to Ordovician, 445 to 542 million years old. About 4 mi of the line.
Graywacke, shale. Age: Middle Ordovician, 459 to 471 million years old. About 3 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Shale, siltstone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Shale, conglomerate, limestone. Age: Cambrian, 487 to 542 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. 6 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 Hudson reaches New York Harbor and the Atlantic Ocean by way of the Hudson: about 120 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hudson; river miles along the main stem, rounded.
Hudson has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 18° in January. A normal year brings about 31 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Hudson normally reaches 52° and falls to 34°. The record high is 71°, in 1989; the record low 14°, in 1986. The most rain on this date, 1.20 in, fell in 1972.
