74° on Nov. 11, 2020, the hottest reading for this week of the year since 1969. Next is 71° in 1989.
Waterloo’s center stands about 460 ft above sea level. Within three miles the land runs from 440 ft to 570 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Locust Hill, about 1,030 ft, 14 miles southwest.
Under the town center the state geologic map shows Onondaga Limestone, from the Early Devonian to Middle Devonian, 388 to 410 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 38×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Early Devonian to Middle Devonian, 388 to 410 million years old. About 10 mi of the line.
Shale. Age: Silurian, 422 to 428 million years old. About 7 mi of the line.
Shale, limestone. Age: Middle Devonian, 384 to 388 million years old. About 3 mi of the line.
Dolostone. Age: Silurian, 422 to 428 million years old. About 2 mi of the line.
Shale. Age: Middle Devonian, 384 to 394 million years old. About 1 mi of the line.
Shale. Age: Middle Devonian, 384 to 388 million years old. About 0.8 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 Waterloo reaches Lake Ontario by way of Gem Creek, the Seneca and the Oswego: about 85 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Lake on the way: Cayuga Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Waterloo; river miles along the main stem, rounded.
Waterloo has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 16° in January. A normal year brings about 57 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Waterloo normally reaches 47° and falls to 32°. The record high is 65°, in 2005; the record low 14°, in 2019. The most rain on this date, 0.62 in, fell in 1972.
Normals 1991–2020 and records since 1969 at Geneva Research Farm, 9 miles west-southwest, 260 ft higher. NOAA, through RCC-ACIS.
