3° on Nov. 16, 1933, the coldest reading for this week of the year since 1893. Next is 11° in 1911.
Aurora’s center stands about 1,130 ft above sea level. Within three miles the land runs from 990 ft to 1,240 ft, a difference of 250 ft: rolling country. The highest named summit within 15 miles is Sugarloaf, about 1,450 ft, 14 miles east-northeast.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 31×. 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, siltstone. Age: Carboniferous, 299 to 324 million years old. About 13 mi of the line.
Shale, siltstone, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 7 mi of the line.
Shale, black-shale. Age: Devonian, 359 to 422 million years old. About 4 mi of the line.
Sandstone, shale. Age: Devonian, 359 to 422 million years old. About 0.6 mi of the line.

A raindrop that lands in Aurora reaches Lake Erie by way of Aurora Branch and the Chagrin: about 40 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Aurora; river miles along the main stem, rounded.
Aurora has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 16° in January. A normal year brings about 63 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Aurora normally reaches 49° and falls to 31°. The record high is 79°, in 1926; the record low 13°, in 2019. The most rain on this date, 1.15 in, fell in 1972.
Normals 1991–2020 and records since 1893 at Hiram, 10 miles east, 100 ft higher. NOAA, through RCC-ACIS.
