78° on Nov. 16, 1993, the hottest reading for this week of the year since 1931. Next is 76° in 1973.
New Providence’s center stands about 230 ft above sea level. Within three miles the land runs from 190 ft to 560 ft, a difference of 370 ft: rolling country. The highest named summit within 15 miles is Calais Mountain, about 1,120 ft, 13 miles northwest.
Under the town center the state geologic map shows Towaco Formation (sandstone, siltstone-mudstone), from the Early Jurassic, 175 to 202 million years old.
The section below crosses 12 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.
Sandstone-mudstone, siltstone-mudstone. Age: Early Jurassic to Late Jurassic, 145 to 202 million years old. About 5 mi of the line.
Siltstone, shale. Age: Early Jurassic to Late Jurassic, 145 to 202 million years old. About 5 mi of the line.
Sandstone, siltstone-mudstone. Age: Early Jurassic, 175 to 202 million years old. About 4 mi of the line.
Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Sandstone, siltstone, mudstone. Age: Early Jurassic, 175 to 202 million years old. About 2 mi of the line.
Biotite-gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 6 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 New Providence reaches New York Harbor and the Atlantic Ocean by way of the Passaic: about 65 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of New Providence; river miles along the main stem, rounded.
New Providence has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 22° in January. A normal year brings about 24 inches of snow; with the rain, that comes to about 50 inches of water.
On November 14 New Providence normally reaches 55° and falls to 35°. The record high is 71°, in 1964; the record low 11°, in 1986. The most rain on this date, 1.51 in, fell in 1937.
Normals 1991–2020 and records since 1931 at Canoe Brook, 4 miles northeast. NOAA, through RCC-ACIS.
