85° on Nov. 14, 2025, the hottest reading for this week of the year since 1895. Next is 82° in 1999.
Grand Island’s center stands about 1,870 ft above sea level. Within three miles the land runs from 1,820 ft to 1,880 ft, a difference of 60 ft: nearly flat ground.
Under the town center the state geologic map shows Niobrara Formation (limestone, 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 64×. 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, shale. Age: Late Cretaceous, 66 to 100 million years old. About 11 mi of the line.
Siltstone-mudstone, conglomerate-sandstone. Age: Miocene, 5.3 to 23 million years old. About 9 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 4 mi of the line.

A raindrop that lands in Grand Island reaches the Gulf of America by way of the Wood, the Platte, the Missouri and the Mississippi: about 1,930 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Grand Island; river miles along the main stem, rounded.
Grand Island has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 16° in January. A normal year brings about 28 inches of snow; with the rain, that comes to about 27 inches of water.
On November 14 Grand Island normally reaches 52° and falls to 29°. The record high is 85°, in 2025; the record low −7°, in 1940. The most rain on this date, 0.75 in, fell in 1947.
