67° on Nov. 15, 2025, the hottest reading for this week of the year since 1930. Next is 66° in 2001.
Larimore’s center stands about 1,140 ft above sea level. Within three miles the land runs from 1,050 ft to 1,140 ft, a difference of 90 ft: gently rolling country.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 32×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 7 mi of the line.

A raindrop that lands in Larimore reaches Hudson Bay by way of the South Branch Turtle, the Turtle, the Red River of the North and the Nelson: about 990 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: Lake Winnipeg.
400 miles of the trip are on the Nelson.

Larimore has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about −4° in January. A normal year brings about 42 inches of snow; with the rain, that comes to about 20 inches of water.
On November 14 Larimore normally reaches 35° and falls to 18°. The record high is 65°, in 1953; the record low −10°, in 1959. The most rain on this date, 0.97 in, fell in 1944.
