94° on Nov. 15, 2025, the hottest reading for this week of the year since 1938. Next is 89° in 1944.
Frederick’s center stands about 1,240 ft above sea level. Within three miles the land runs from 1,180 ft to 1,280 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Garber Sandstone (sandstone, conglomerate), from the Permian, 252 to 299 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 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.
Sandstone, conglomerate. Age: Permian, 252 to 299 million years old. About 15 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 9 mi of the line.

A raindrop that lands in Frederick reaches the Gulf of America by way of Suttle Creek, the Red River, the Atchafalaya and the Lower Atchafalaya: about 1,080 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Frederick; river miles along the main stem, rounded.
Frederick has a humid subtropical climate. Summer afternoons average 97° in July; winter nights fall to about 28° in January. About 28 inches of rain fall in a normal year.
On November 14 Frederick normally reaches 64° and falls to 38°. The record high is 89°, in 2025; the record low 18°, in 1940. The most rain on this date, 0.86 in, fell in 1947.
