76° on Nov. 14, 1999, the hottest reading for this week of the year since 1893. Next is 73° in 2012.
Sharon’s center stands about 990 ft above sea level. Within three miles the land runs from 900 ft to 1,030 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Klondike Hill, about 1,180 ft, 14 miles south-southeast.
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 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 54×. 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 14 mi of the line.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 7 mi of the line.
Shale, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 3 mi of the line.

A raindrop that lands in Sharon reaches the Gulf of America by way of Le Sueur Creek, the Minnesota and the Mississippi: about 1,900 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Sharon; river miles along the main stem, rounded.
Sharon has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 3° in January. A normal year brings about 38 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Sharon normally reaches 43° and falls to 23°. The record high is 76°, in 1999; the record low −8°, in 1959. The most rain on this date, 1.50 in, fell in 1997.
Normals 1991–2020 and records since 1893 at St. Peter, 10 miles southwest, 200 ft lower. NOAA, through RCC-ACIS.
