78° on Nov. 15, 1993, the hottest reading for this week of the year since 1948. Next is 72° in 2022.
Orange’s center stands about 210 ft above sea level. Within three miles the land runs from 30 ft to 350 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is Mount Sanford, about 930 ft, 13 miles north-northeast.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 25×. 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.
Schist, granofels. Age: Early Ordovician, 471 to 487 million years old. About 3 mi of the line.
Gneiss. Age: Middle Ordovician, 459 to 471 million years old. About 2 mi of the line.
Schist. Age: Silurian to Devonian, 359 to 445 million years old. About 1 mi of the line.
Greenstone. Age: Middle Ordovician, 459 to 471 million years old. About 0.9 mi of the line.
Greenstone, schist. Age: Middle Ordovician, 459 to 471 million years old. About 0.6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Orange reaches Long Island Sound and the Atlantic Ocean by way of Race Brook and the Wepawaug: about 7 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Orange; river miles along the main stem, rounded.
Orange has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 25° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Orange normally reaches 54° and falls to 39°. The record high is 68°, in 1959; the record low 20°, in 1986. The most rain on this date, 2.84 in, fell in 1972.
Normals 1991–2020 and records since 1948 from the Bridgeport Area threaded record (Igor I Sikorsky Memorial Airport, 10 miles south-southwest, 200 ft lower). NOAA, through RCC-ACIS.
