−3° on Nov. 17, 1959, the coldest reading for this week of the year since 1929. Next is −3° in 1986.
Washington’s center stands about 1,060 ft above sea level. Within three miles the land runs from 1,040 ft to 1,160 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Bald Hill, about 1,730 ft, 14 miles northwest.
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 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 36×. 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 17 mi of the line.
Metavolcanic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 4 mi of the line.
Gneiss. Age: Mesoarchean to Neoarchean, 2.5 to 2.9 billion years old. About 2 mi of the line.
Quartzite, conglomerate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 1 mi of the line.

A raindrop that lands in Washington reaches the Gulf of America by way of the Flambeau, the Chippewa and the Mississippi: about 1,860 river miles.
Lakes on the way: Lake Wissota and Holcombe Flowage.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Washington; river miles along the main stem, rounded.
Washington has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 2° in January. About 33 inches of rain fall in a normal year.
On November 14 Washington normally reaches 40° and falls to 24°. The record high is 65°, in 1990; the record low 3°, in 1959. The most rain on this date, 0.75 in, fell in 2005.
Normals 1991–2020 and records since 1929 at Holcombe, 9 miles southeast. NOAA, through RCC-ACIS.
