72° on Nov. 14, 1999, the hottest reading for this week of the year since 1954. Next is 71° in 2001.
Harrisville’s center stands about 820 ft above sea level. Within three miles the land runs from 810 ft to 950 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Observatory Hill, about 1,110 ft, 12 miles south-southeast.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 42×. 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 24 mi of the line.

A raindrop that lands in Harrisville reaches Lake Michigan by way of the Montello and the Fox River: about 150 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lakes on the way: Lake Winnebago 6124, Lake Butte des Morts and Puckaway Lake.
50 miles of the trip are on the Fox River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Harrisville; river miles along the main stem, rounded.
Harrisville has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 8° in January. A normal year brings about 42 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 Harrisville normally reaches 45° and falls to 27°. The record high is 72°, in 1999; the record low 3°, in 1986. The most rain on this date, 1.53 in, fell in 1956.
Normals 1991–2020 and records since 1954 at Montello Wwtp, 8 miles south-southeast. NOAA, through RCC-ACIS.
