Havana’s center stands about 380 ft above sea level. Within three miles the land runs from 340 ft to 820 ft, a difference of 480 ft: hilly country. The highest named summit within 15 miles is Signal Hill, about 2,760 ft, 8 miles west-northwest.
Under the town center the state geologic map shows Atoka Formation - Lower part (sandstone, shale), from the Carboniferous, 299 to 324 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Havana reaches the Gulf of America by way of Big Piney Creek, the Petit Jean, the Arkansas and the Mississippi: about 860 river miles.
Lake on the way: Murray 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 93° in July; winter nights fall to about 28° in January. About 50 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Havana normally reaches 63° and falls to 38°. The record high is 83°, in 2007; the record low 20°, in 2019. The most rain on this date, 1.41 in, fell in 1993.
Normals 1991–2020 and records since 1939 at Blue Mountain Dam, 7 miles west. NOAA, through RCC-ACIS.
