71° on Nov. 11, 2022, the hottest reading for this week of the year since 1939. Next is 70° in 1999.
Arcadia’s center stands about 730 ft above sea level. Within three miles the land runs from 710 ft to 1,090 ft, a difference of 380 ft: rolling country. The highest named summit within 15 miles is Square Bluff, about 1,300 ft, 9 miles east-northeast.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 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 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.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 14 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 11 mi of the line.

A raindrop that lands in Arcadia reaches the Gulf of America by way of the Trempealeau and the Mississippi: about 1,730 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Arcadia; river miles along the main stem, rounded.
Arcadia has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 8° in January. A normal year brings about 38 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Arcadia normally reaches 44° and falls to 30°. The record high is 70°, in 1999; the record low 3°, in 1996. The most rain on this date, 0.40 in, fell in 2010.
Normals 1991–2020 and records since 1939 at Winona Dam 5 A, 14 miles southwest. NOAA, through RCC-ACIS.
