8.02 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 5.17 inches, fell in 2000.
Rayne’s center stands about 40 ft above sea level. Within three miles the land runs from 20 ft to 50 ft, a difference of 30 ft: nearly flat ground.
Under the town center the state geologic map shows Prairie Terraces (clay, silt, sand), from the Pleistocene, less than 2.6 million years old.
The section below crosses 3 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.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 12 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 11 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 2 mi of the line.

A raindrop that lands in Rayne reaches the Gulf of America by way of the Coulee Duralde, the Bayou Wikoff, the Bayou Plaquemine Brule and the Mermentau: about 100 river miles.
Lake on the way: Lake Arthur.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Rayne; river miles along the main stem, rounded.
Rayne has a humid subtropical climate. Summer afternoons average 92° in August; winter nights fall to about 43° in January. About 63 inches of rain fall in a normal year.
On November 14 Rayne normally reaches 72° and falls to 50°. The record high is 87°, in 1951; the record low 29°, in 1911. The most rain on this date, 3.22 in, fell in 1989.
Normals 1991–2020 and records since 1893 at Lafayette Regional Airport, 17 miles east. NOAA, through RCC-ACIS.
