1° on Nov. 17, 1959, the coldest reading for this week of the year since 1896. Next is 4° in 1933.
North Bay’s center stands about 630 ft above sea level. Within three miles the land runs from 570 ft to 700 ft, a difference of 130 ft: gently rolling country.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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. Age: Silurian, 422 to 445 million years old. About 12 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

Rain that falls on North Bay runs straight into Lake Michigan. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of North Bay; river miles along the main stem, rounded.
North Bay has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 14° in January. A normal year brings about 41 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 North Bay normally reaches 47° and falls to 32°. The record high is 72°, in 1971; the record low 7°, in 1986. The most rain on this date, 1.50 in, fell in 1899.
Normals 1991–2020 and records since 1896 at Racine Wwtp, 4 miles south. NOAA, through RCC-ACIS.
