72° on Nov. 17, 1953, the hottest reading for this week of the year since 1916. Next is 69° in 1931.
Presque Isle’s center stands about 630 ft above sea level. Within three miles the land runs from 520 ft to 720 ft, a difference of 200 ft: gently rolling country.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 62×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Middle Devonian, 384 to 394 million years old. About 12 mi of the line.
Limestone. Age: Middle Devonian, 384 to 394 million years old. About 7 mi of the line.

A raindrop that lands in Presque Isle reaches Lake Huron by way of Grand Lake and the Grand Lake Outlet: about 7 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lake on the way: Grand Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Presque Isle; river miles along the main stem, rounded.
Presque Isle has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 11° in February. A normal year brings about 78 inches of snow; with the rain, that comes to about 30 inches of water.
On November 14 Presque Isle normally reaches 45° and falls to 29°. The record high is 66°, in 1994; the record low 3°, in 1940. The most rain on this date, 0.61 in, fell in 1957.
Normals 1991–2020 and records since 1916 from the Alpena Area threaded record (Alpena County Regional Airport, 14 miles south-southwest). NOAA, through RCC-ACIS.
