19° on Nov. 13, 2019, the coldest reading for this week of the year since 1903. Next is 21° in 1997.
Pine Harbor’s center stands about 330 ft above sea level. Within three miles the land runs from 210 ft to 390 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Buzzard Roost Mountain, about 560 ft, 14 miles northwest.
Under the town center the state geologic map shows Queen City Sand (siltstone, sandstone), from the Middle Eocene, 38 to 48 million years old.
The section below crosses 4 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.
Siltstone, sandstone. Age: Middle Eocene, 38 to 48 million years old. About 14 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Mudstone. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 3 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.

A raindrop that lands in Pine Harbor reaches the Gulf of America by way of Lake O' the Pines, Big Cypress Bayou, Twelvemile Bayou, Cross Bayou, the Red River, the Atchafalaya and the Lower Atchafalaya: about 480 river miles.
Lakes on the way: Clear Lake and Lake O' the Pines.
260 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pine Harbor; river miles along the main stem, rounded.
Pine Harbor has a humid subtropical climate. Summer afternoons average 94° in July; winter nights fall to about 34° in January. About 50 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Pine Harbor normally reaches 67° and falls to 42°. The record high is 82°, in 2007; the record low 19°, in 2019. The most rain on this date, 1.52 in, fell in 1970.
Normals 1991–2020 and records since 1903 at Jefferson, 8 miles east, 120 ft lower. NOAA, through RCC-ACIS.
