20° on Nov. 13, 2019, the coldest reading for this week of the year since 1976. Next is 28° in 1982.
Boyce’s center stands about 90 ft above sea level. Within three miles the land runs from 60 ft to 160 ft, a difference of 100 ft: gently rolling country. The highest named summit within 15 miles is Sunk Hill, about 320 ft, 13 miles west-northwest.
Under the town center the state geologic map shows Natural Levees (silt, clay), from the Holocene, less than 12,000 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.
Clay. Age: Holocene, less than 12,000 years old. About 11 mi of the line.
Silt, clay. Age: Holocene, less than 12,000 years old. About 6 mi of the line.
Siltstone, sandstone, clay. Age: Miocene, 5.3 to 23 million years old. About 3 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in Boyce reaches the Gulf of America by way of the Bayou Bertrand, Saline Bayou, the Bayou Rapides, the Red River, the Atchafalaya and the Lower Atchafalaya: about 260 river miles.
100 miles of the trip are on the Atchafalaya.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Boyce; river miles along the main stem, rounded.
Boyce has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 39° in January. About 61 inches of rain fall in a normal year.
On November 14 Boyce normally reaches 66° and falls to 46°. The record high is 83°, in 1985; the record low 28°, in 2014. The most rain on this date, 1.51 in, fell in 1993.
Normals 1991–2020 and records since 1976 at Boyce 3 WNW, 3 miles west. NOAA, through RCC-ACIS.
