10° on Nov. 16, 1996, the coldest reading for this week of the year since 1937. Next is 14° in 1956.
Brewster Heights’s center stands about 650 ft above sea level. Within three miles the land runs from 310 ft to 770 ft, a difference of 460 ft: hilly country. The highest named summit within 15 miles is Depot Hill, about 1,340 ft, 11 miles north-northwest.
Under the town center the state geologic map shows Biotite-quartz-plagioclase gneiss (biotite-gneiss), from the Mesoproterozoic, 1 to 1.6 billion years old.
The section below crosses 10 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.
Pelitic-schist, gneiss, amphibolite. Age: Early Cambrian to Middle Ordovician, 459 to 542 million years old. About 8 mi of the line.
Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Biotite-gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Gneiss. Age: Precambrian to Mesoproterozoic. About 2 mi of the line.
Gneiss. Age: Precambrian to Mesoproterozoic. 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. 4 smaller units along the line are not listed.

A raindrop that lands in Brewster Heights reaches New York Harbor and the Atlantic Ocean by way of the East Branch Croton, the Croton and the Hudson: about 60 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Brewster Heights; river miles along the main stem, rounded.
Brewster Heights has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 21° in January. A normal year brings about 49 inches of snow; with the rain, that comes to about 53 inches of water.
On November 14 Brewster Heights normally reaches 51° and falls to 34°. The record high is 73°, in 1993; the record low 16°, in 1939. The most rain on this date, 2.42 in, fell in 1937.
Normals 1991–2020 and records since 1937 at Danbury, 11 miles east, 240 ft lower. NOAA, through RCC-ACIS.
