65° on Nov. 14, 2025, the hottest reading for this week of the year since 1924. Next is 61° in 1981.
West Roy Lake’s center stands about 1,520 ft above sea level. Within three miles the land runs from 1,460 ft to 1,800 ft, a difference of 340 ft: rolling country. The highest named summit within 15 miles is Jack Pine Hill, about 1,990 ft, 6 miles southeast.
Under the town center the state geologic map shows Granitic intrusion, from the Neoarchean, 2.5 to 2.8 billion years old.
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 29×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 22 mi of the line.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 2 mi of the line.

A raindrop that lands in West Roy Lake reaches Hudson Bay by way of Roy Lake Creek, the Wild Rice, the Red River of the North and the Nelson: about 1,190 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.

West Roy Lake has a warm-summer humid continental climate. Summer afternoons average 78° in July; winter nights fall to about −2° in January. About 26 inches of rain fall in a normal year.
On November 14 West Roy Lake normally reaches 34° and falls to 20°. The record high is 65°, in 2025; the record low −8°, in 1959. The most rain on this date, 0.50 in, fell in 1951.
