12° on Nov. 16, 1996, the coldest reading for this week of the year since 1956. Next is 14° in 1956.
Noank’s center stands about 50 ft above sea level. Within three miles the land runs from 0 ft to 230 ft, a difference of 230 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Chapel Hill, about 650 ft, 15 miles northwest.
Under the town center the state geologic map shows Rope Ferry Gneiss, from the Neoproterozoic, 617 to 623 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 37×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Quartzite. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Gneiss. Age: Neoproterozoic, 542 to 1,000 million years old. About 2 mi of the line.

Rain that falls on Noank runs straight into Long Island Sound and the Atlantic Ocean.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Noank; river miles along the main stem, rounded.
Noank has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 21° in January. A normal year brings about 28 inches of snow; with the rain, that comes to about 52 inches of water.
On November 14 Noank normally reaches 54° and falls to 35°. The record high is 72°, in 1993; the record low 17°, in 1986. The most rain on this date, 2.25 in, fell in 1972.
Normals 1991–2020 and records since 1956 at Norwich Public Utility Plant, 14 miles north-northwest. NOAA, through RCC-ACIS.
