The Tupman plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
87° on Nov. 11, 1973, the hottest reading for this week of the year since 1940. Next is 86° in 2016.
Tupman’s center stands about 340 ft above sea level. Within three miles the land runs from 280 ft to 960 ft, a difference of 680 ft: hilly country. The highest named summit within 15 miles is Twentyfive Hill, about 1,710 ft, 14 miles south-southwest.
Under the town center the state geologic map shows Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 18×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 15 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 9 mi of the line.

Tupman has a hot desert climate. Summer afternoons average 98° in July; winter nights fall to about 36° in December. About 6 inches of rain fall in a normal year.
On November 14 Tupman normally reaches 68° and falls to 41°. The record high is 82°, in 1990; the record low 30°, in 1985. The most rain on this date, 0.39 in, fell in 1953.
