5° on Nov. 17, 1996, the coldest reading for this week of the year since 1904. Next is 6° in 1924.
Newington’s center stands about 100 ft above sea level. Within three miles the land runs from 50 ft to 350 ft, a difference of 300 ft: rolling country. The highest named summit within 15 miles is Johnnycake Mountain, about 1,190 ft, 14 miles west-northwest.
Under the town center the state geologic map shows Portland Arkose (arkose, siltstone), from the Early Jurassic, 175 to 202 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 20×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Arkose, siltstone. Age: Early Jurassic, 175 to 202 million years old. About 13 mi of the line.
Arkose. Age: Late Triassic to Early Jurassic, 175 to 237 million years old. About 5 mi of the line.
Siltstone, shale. Age: Early Jurassic, 175 to 202 million years old. About 3 mi of the line.
Basalt, gabbro. Age: Early Jurassic, 175 to 202 million years old. About 2 mi of the line.
Schist, granofels. Age: Silurian to Devonian, 359 to 445 million years old. About 0.8 mi of the line.
Shale. Age: Early Jurassic, 175 to 202 million years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Newington reaches Long Island Sound and the Atlantic Ocean by way of Mill Brook, Piper Brook, the South Branch Park and the Connecticut: about 60 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Newington; river miles along the main stem, rounded.
Newington has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 20° in January. About 43 inches of rain fall in a normal year.
On November 14 Newington normally reaches 53° and falls to 35°. The record high is 71°, in 1959; the record low 15°, in 1996. The most rain on this date, 1.07 in, fell in 1940.
Normals 1991–2020 and records since 1904 at Hartford Brainard Field, 5 miles east-northeast. NOAA, through RCC-ACIS.
