−12° on Nov. 12, 1966, the coldest reading for this week of the year since 1945. Next is −8° in 1959.
Langhei’s center stands about 1,200 ft above sea level. Within three miles the land runs from 1,070 ft to 1,380 ft, a difference of 310 ft: rolling country.
Under the town center the state geologic map shows Granitoid gneiss with dioritic to amphibolitic enclaves (orthogneiss), from the Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 54×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Orthogneiss, migmatite. Age: Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old. About 8 mi of the line.
Orthogneiss. Age: Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old. About 8 mi of the line.
Orthogneiss. Age: Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old. About 6 mi of the line.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 3 mi of the line.

A raindrop that lands in Langhei reaches the Gulf of America by way of the East Branch Chippewa, the Chippewa, the Minnesota and the Mississippi: about 2,160 river miles.
Lake on the way: Lake Pepin.
1,750 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Langhei; river miles along the main stem, rounded.
Langhei has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 1° in January. A normal year brings about 43 inches of snow; with the rain, that comes to about 28 inches of water.
On November 14 Langhei normally reaches 42° and falls to 22°. The record high is 69°, in 1990; the record low −5°, in 2014. The most rain on this date, 0.40 in, fell in 2024.
Normals 1991–2020 and records since 1945 at Benson, 10 miles south-southwest, 170 ft lower. NOAA, through RCC-ACIS.
