84° on Nov. 11, 1949, the hottest reading for this week of the year since 1893. Next is 84° in 1989.
Havana’s center stands about 760 ft above sea level. Within three miles the land runs from 740 ft to 960 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Berry Hill, about 1,040 ft, 5 miles northeast.
Under the town center the state geologic map shows Douglas Group (shale, sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 62×. 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, sandstone. Age: Carboniferous, 299 to 324 million years old. About 12 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
Shale, limestone. Age: Carboniferous, 299 to 324 million years old. About 0.4 mi of the line.

A raindrop that lands in Havana reaches the Gulf of America by way of Bee Creek, the Little Caney, the Caney, the Verdigris, the Arkansas and the Mississippi: about 1,190 river miles.
Lakes on the way: Murray Lake, Ozark Lake and Copan Lake.
600 miles of the trip are on the Mississippi.
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 humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 22° in January. A normal year brings about 9 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Havana normally reaches 60° and falls to 35°. The record high is 83°, in 1999; the record low 8°, in 1986. The most rain on this date, 1.15 in, fell in 1924.
Normals 1991–2020 and records since 1893 at Sedan, 13 miles west-northwest, 140 ft higher. NOAA, through RCC-ACIS.
