4° on Nov. 16, 1933, the coldest reading for this week of the year since 1893. Next is 5° in 1911.
Rudolph’s center stands about 680 ft above sea level. Within three miles the land runs from 670 ft to 740 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Tymochtee and Greenfield Formations, Undivided (dolostone), from the Silurian, 428 to 445 million years old.
The section below crosses 2 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.
Dolostone. Age: Silurian, 425 to 445 million years old. About 13 mi of the line.
Dolostone. Age: Silurian, 428 to 445 million years old. About 12 mi of the line.

A raindrop that lands in Rudolph reaches Lake Erie by way of the Middle Branch Portage and the Portage: about 55 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 Rudolph; river miles along the main stem, rounded.
Rudolph has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 19° in January. A normal year brings about 21 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Rudolph normally reaches 50° and falls to 34°. The record high is 73°, in 2010; the record low 12°, in 1986. The most rain on this date, 1.16 in, fell in 1972.
Normals 1991–2020 and records since 1893 at Bowling Green Wwtp, 7 miles north-northeast. NOAA, through RCC-ACIS.
