Webster’s center stands about 470 ft above sea level. Within three miles the land runs from 420 ft to 830 ft, a difference of 410 ft: hilly country. The highest named summit within 15 miles is Coye Hill, about 1,130 ft, 13 miles west-southwest.
The section below crosses 13 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 28×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granofels, schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 6 mi of the line.
Granite, tonalite. Age: Silurian, 428 to 445 million years old. About 5 mi of the line.
Gneiss. Age: Ordovician to Middle Ordovician, 459 to 487 million years old. About 4 mi of the line.
Gneiss, schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 2 mi of the line.
Metasedimentary, muscovite-schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 2 mi of the line.
Schist, gneiss. Age: Neoproterozoic, 542 to 1,000 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 7 smaller units along the line are not listed.

A raindrop that lands in Webster reaches Long Island Sound and the Atlantic Ocean by way of the French, the Quinebaug, the Shetucket and the Thames: about 75 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Webster; river miles along the main stem, rounded.
Webster 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 Webster 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.
Normals 1991–2020 and records since 1959 at Buffumville Lake, 5 miles north-northwest. NOAA, through RCC-ACIS.
