72° on Nov. 14, 2025, the hottest reading for this week of the year since 1871. Next is 71° in 1953.
Sunfish Lake’s center stands about 990 ft above sea level. Within three miles the land runs from 810 ft to 1,060 ft, a difference of 250 ft: rolling country. The highest named summit within 15 miles is Buck Hill, about 1,180 ft, 14 miles southwest.
Under the town center the state geologic map shows Middle and Upper Ordovician (shale, limestone, sandstone), from the Middle Ordovician to Late Ordovician, 445 to 471 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 47×. 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, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 16 mi of the line.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 6 mi of the line.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 2 mi of the line.

A raindrop that lands in Sunfish Lake reaches the Gulf of America by way of the Mississippi: about 1,810 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Sunfish Lake; river miles along the main stem, rounded.
Sunfish Lake has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 9° in January. A normal year brings about 51 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Sunfish Lake normally reaches 43° and falls to 28°. The record high is 72°, in 2025; the record low 0°, in 1919. The most rain on this date, 0.80 in, fell in 1926.
Normals 1991–2020 and records since 1871 from the Minneapolis-St Paul Area threaded record (Minneapolis-St. Paul International Airport, 7 miles west, 160 ft lower). NOAA, through RCC-ACIS.
