The Dudley plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
75° on Nov. 16, 1993, the hottest reading for this week of the year since 1959. Next is 73° in 2020.
Dudley’s center stands about 650 ft above sea level. Within three miles the land runs from 360 ft to 790 ft, a difference of 430 ft: hilly country. The highest named summit within 15 miles is Burley Hill, about 1,320 ft, 14 miles west.
Under the town center the state geologic map shows Paxton Formation (granofels, schist), from the Neoproterozoic, 542 to 1,000 million years old.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 26×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granite. Age: Neoproterozoic, 542 to 1,000 million years old. About 5 mi of the line.
Granofels, schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Granite, tonalite. Age: Silurian, 428 to 445 million years old. About 3 mi of the line.
Granofels, schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Granofels, schist. Age: Cambrian to Ordovician, 445 to 542 million years old. About 3 mi of the line.
Schist. Age: Cambrian to Ordovician, 445 to 542 million years old. About 3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 4 smaller units along the line are not listed.

A raindrop that lands in Dudley reaches Long Island Sound and the Atlantic Ocean by way of the Quinebaug, the Shetucket and the Thames: about 70 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Dudley; river miles along the main stem, rounded.
Dudley has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 15° in January. A normal year brings about 47 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Dudley normally reaches 51° and falls to 30°. The record high is 68°, in 1964; the record low 11°, in 1986. The most rain on this date, 1.12 in, fell in 1988.
