83° on Nov. 16, 1941, the hottest reading for this week of the year since 1938. Next is 80° in 1999.
Martin’s center stands about 3,300 ft above sea level. Within three miles the land runs from 3,120 ft to 3,440 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is Bear Hill, about 3,890 ft, 13 miles north-northwest.
Under the town center the state geologic map shows Ogallala Group or Formation (siltstone-mudstone, conglomerate-sandstone), from the Miocene, 5.3 to 23 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 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone-mudstone, conglomerate-sandstone. Age: Miocene, 5.3 to 23 million years old. About 21 mi of the line.
Clay. Age: Early Oligocene to Late Oligocene, 23 to 34 million years old. About 3 mi of the line.

A raindrop that lands in Martin reaches the Gulf of America by way of the North Platte, the Platte, the Missouri and the Mississippi: about 2,140 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 Martin; river miles along the main stem, rounded.
Martin has a dry-winter hot-summer continental climate. Summer afternoons average 87° in July; winter nights fall to about 18° in January. A normal year brings about 21 inches of snow; with the rain, that comes to about 19 inches of water.
On November 14 Martin normally reaches 49° and falls to 29°. The record high is 79°, in 2025; the record low −6°, in 1940. The most rain on this date, 0.40 in, fell in 1993.
Normals 1991–2020 and records since 1938 at Kingsley Dam, 3 miles south-southeast. NOAA, through RCC-ACIS.
