94° on Nov. 15, 2025, the hottest reading for this week of the year since 1938. Next is 89° in 1944.
Elmer’s center stands about 1,310 ft above sea level. Within three miles the land runs from 1,250 ft to 1,370 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Terrace Deposits (coarse-detrital, fine-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 8 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.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Shale, siltstone. Age: Permian, 252 to 299 million years old. About 4 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 4 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Sandstone, conglomerate, shale. Age: Permian, 252 to 299 million years old. About 3 mi of the line.
Gypsum, dolostone, shale. Age: Permian, 252 to 299 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Elmer reaches the Gulf of America by way of the Red River, the Atchafalaya and the Lower Atchafalaya: about 1,110 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Elmer; river miles along the main stem, rounded.
Elmer 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 Elmer 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.
Normals 1991–2020 and records since 1938 at Tipton 4 S Mesonet, 13 miles east-southeast. NOAA, through RCC-ACIS.
