75° on Nov. 12, 2022, the hottest reading for this week of the year since 1948. Next is 70° in 2024.
Woodbridge’s center stands about 370 ft above sea level. Within three miles the land runs from 60 ft to 600 ft, a difference of 540 ft: hilly country. The highest named summit within 15 miles is Great Hill, about 1,000 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Wepawaug Schist (schist, phyllite), from the Silurian to Devonian, 359 to 445 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 23×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Schist, phyllite. Age: Silurian to Devonian, 359 to 445 million years old. About 7 mi of the line.
Gneiss, schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 4 mi of the line.
Gneiss. Age: Middle Ordovician, 459 to 471 million years old. About 3 mi of the line.
Schist, granofels. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.
Schist. Age: Silurian to Devonian, 359 to 445 million years old. About 2 mi of the line.
Greenstone. Age: Middle Ordovician, 459 to 471 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. 5 smaller units along the line are not listed.

A raindrop that lands in Woodbridge reaches Long Island Sound and the Atlantic Ocean by way of the Wepawaug: about 12 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Woodbridge; river miles along the main stem, rounded.
Woodbridge has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 23° in January. About 42 inches of rain fall in a normal year.
On November 14 Woodbridge normally reaches 54° and falls to 36°. The record high is 69°, in 1959; the record low 20°, in 2019. The most rain on this date, 2.19 in, fell in 1972.
Normals 1991–2020 and records since 1948 at New Haven Tweed Airport, 9 miles southeast, 360 ft lower. NOAA, through RCC-ACIS.
