74° on Nov. 14, 1999, the hottest reading for this week of the year since 1938. Next is 72° in 2022.
Zumbro Falls’s center stands about 970 ft above sea level. Within three miles the land runs from 830 ft to 1,120 ft, a difference of 290 ft: rolling country. The highest named summit within 15 miles is Kohn Hill, about 1,160 ft, 14 miles north.
Under the town center the state geologic map shows Lower Ordovician (dolostone, sandstone), from the Early Ordovician, 471 to 487 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 49×. 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, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 21 mi of the line.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 3 mi of the line.

A raindrop that lands in Zumbro Falls reaches the Gulf of America by way of the Zumbro and the Mississippi: about 1,770 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Zumbro Falls; river miles along the main stem, rounded.
Zumbro Falls has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 4° in January. A normal year brings about 48 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 Zumbro Falls normally reaches 44° and falls to 25°. The record high is 74°, in 1999; the record low 3°, in 1996. The most rain on this date, 0.69 in, fell in 1951.
Normals 1991–2020 and records since 1938 at Theilman 1 SSW, 12 miles east, 220 ft lower. NOAA, through RCC-ACIS.
