2° on Nov. 13, 2019, the coldest reading for this week of the year since 1981. Next is 9° in 1986.
Cayuga’s center stands about 530 ft above sea level. Within three miles the land runs from 480 ft to 690 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Raccoon Creek Group (shale, sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 12 mi of the line.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 5 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Shale, sandstone, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 3 mi of the line.
Siltstone. Age: Carboniferous, 324 to 359 million years old. About 0.9 mi of the line.

A raindrop that lands in Cayuga reaches the Gulf of America by way of Dry Branch, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,350 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Cayuga; river miles along the main stem, rounded.
Cayuga has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 17° in January. A normal year brings about 19 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Cayuga normally reaches 53° and falls to 32°. The record high is 73°, in 1989; the record low 8°, in 2019. The most rain on this date, 1.07 in, fell in 1993.
Normals 1991–2020 and records since 1981 at Perrysville 4 WNW, 9 miles north-northwest. NOAA, through RCC-ACIS.
