17° on Nov. 15, 1996, the coldest reading for this week of the year since 1946. Next is 18° in 1967.
Blauvelt’s center stands about 230 ft above sea level. Within three miles the land runs from 20 ft to 600 ft, a difference of 580 ft: hilly country. Open water lies within three miles. The highest named summit within 15 miles is Jackie Jones Mountain, about 1,310 ft, 12 miles north-northwest.
Under the town center the state geologic map shows Brunswick Formation (mudstone, sandstone, arkose), from the Late Triassic, 202 to 237 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 36×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mudstone, sandstone, arkose. Age: Late Triassic, 202 to 237 million years old. About 10 mi of the line.
Sandstone, siltstone. Age: Early Jurassic to Late Jurassic, 145 to 202 million years old. About 6 mi of the line.
Arkose. Age: Late Jurassic, 145 to 164 million years old. About 2 mi of the line.
Plutonic. Age: Early Jurassic, 175 to 202 million years old. About 1 mi of the line.
Basalt. Age: Early Jurassic, 175 to 202 million years old. About 1 mi of the line.
Argillite. Age: Late Jurassic, 145 to 164 million years old. About 0.4 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 Blauvelt reaches New York Harbor and the Atlantic Ocean by way of the Hackensack: about 40 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Blauvelt; river miles along the main stem, rounded.
Blauvelt has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 23° in January. About 48 inches of rain fall in a normal year.
On November 14 Blauvelt normally reaches 53° and falls to 37°. The record high is 71°, in 1993; the record low 20°, in 1986. The most rain on this date, 1.92 in, fell in 1972.
Normals 1991–2020 and records since 1946 at Westchester Co Airport, 13 miles east, 140 ft higher. NOAA, through RCC-ACIS.
