85° on Nov. 14, 2025, the hottest reading for this week of the year since 1895. Next is 82° in 1999.
Aurora’s center stands about 1,800 ft above sea level. Within three miles the land runs from 1,740 ft to 1,820 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Niobrara Formation (limestone, shale), from the Late Cretaceous, 66 to 100 million years old.
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 24 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Aurora reaches the Gulf of America by way of Lincoln Creek, the Big Blue, the Kansas, the Missouri and the Mississippi: about 2,000 river miles.
Lake on the way: Tuttle Creek Lake.
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 Aurora; river miles along the main stem, rounded.
Aurora 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 Aurora 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.
Normals 1991–2020 and records since 1895 from the Grand Island Area threaded record (Grand Island Central Ne Regional Airport, 17 miles west-northwest). NOAA, through RCC-ACIS.
