10° on Nov. 16, 1996, the coldest reading for this week of the year since 1937. Next is 14° in 1956.
Brookfield Center’s center stands about 510 ft above sea level. Within three miles the land runs from 190 ft to 680 ft, a difference of 490 ft: hilly country. The highest named summit within 15 miles is Observatory Hill, about 1,330 ft, 12 miles northwest.
Under the town center the state geologic map shows Ordovician? granitic gneiss, from the Early Devonian to Middle Devonian, 393 to 419 million years old.
The section below crosses 14 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 16×. 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, granofels. Age: Cambrian to Early Ordovician, 471 to 542 million years old. About 6 mi of the line.
Granofels. Age: Middle Ordovician, 459 to 471 million years old. About 3 mi of the line.
Pelitic-schist, gneiss, amphibolite. Age: Early Cambrian to Middle Ordovician, 459 to 542 million years old. About 3 mi of the line.
Gneiss, amphibolite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Gneiss. Age: Early Devonian to Middle Devonian, 393 to 419 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. 8 smaller units along the line are not listed.

A raindrop that lands in Brookfield Center reaches Long Island Sound and the Atlantic Ocean by way of the Still and the Housatonic: about 50 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Brookfield Center; river miles along the main stem, rounded.
Brookfield Center 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 Brookfield Center 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, 5 miles south-southwest, 100 ft lower. NOAA, through RCC-ACIS.
