71° on Nov. 17, 1953, the hottest reading for this week of the year since 1893. Next is 71° in 2001.
Havana’s center stands about 1,290 ft above sea level. Within three miles the land runs from 1,250 ft to 1,310 ft, a difference of 60 ft: gently rolling country. The highest named summit within 15 miles is Pleasant Peak, about 2,060 ft, 12 miles southeast.
Under the town center the state geologic map shows Carlile Formation (shale), from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 28×. 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 14 mi of the line.
Chalk, marlstone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 9 mi of the line.
Shale, bentonite. Age: Late Cretaceous, 66 to 100 million years old. About 1 mi of the line.

A raindrop that lands in Havana reaches Hudson Bay by way of the Wild Rice, the Red River of the North and the Nelson: about 1,350 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: Lake Winnipeg.
470 miles of the trip are on the Red River of the North.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Havana; river miles along the main stem, rounded.
Havana has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 0° in January. About 23 inches of rain fall in a normal year.
On November 14 Havana normally reaches 39° and falls to 20°. The record high is 67°, in 2016; the record low −13°, in 1940. The most rain on this date, 0.55 in, fell in 1971.
Normals 1991–2020 and records since 1893 at Forman 5 SSE, 6 miles north-northeast. NOAA, through RCC-ACIS.
