19° on Nov. 13, 2019, the coldest reading for this week of the year since 1902. Next is 20° in 1916.
Lakeport’s center stands about 340 ft above sea level. Within three miles the land runs from 240 ft to 390 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Holland Mountain, about 530 ft, 9 miles southwest.
Under the town center the state geologic map shows Reklaw Formation (sandstone), from the Eocene, 34 to 56 million years old.
The section below crosses 5 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. Age: Eocene, 34 to 56 million years old. About 17 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Siltstone, sandstone. Age: Middle Eocene, 38 to 48 million years old. About 0.4 mi of the line.

A raindrop that lands in Lakeport reaches the Gulf of America by way of the Sabine: about 330 river miles.
Lakes on the way: Toledo Bend Reservoir and Sabine Lake.
140 miles of the trip are on the Sabine.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lakeport; river miles along the main stem, rounded.
Lakeport has a humid subtropical climate. Summer afternoons average 95° in August; winter nights fall to about 37° in January. About 45 inches of rain fall in a normal year.
On November 14 Lakeport normally reaches 68° and falls to 45°. The record high is 89°, in 1955; the record low 22°, in 1907. The most rain on this date, 1.25 in, fell in 1970.
