65° on Nov. 13, 2016, the hottest reading for this week of the year since 1965. Next is 65° in 2025.
Manvel’s center stands about 830 ft above sea level. Within three miles the land runs from 810 ft to 840 ft, a difference of 30 ft: nearly flat ground.
Under the town center the state geologic map shows Inyan Kara (sandstone, shale), from the Early Cretaceous, 100 to 145 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.
Sandstone, shale. Age: Early Cretaceous, 100 to 145 million years old. About 9 mi of the line.
Limestone, dolostone. Age: Late Ordovician, 445 to 459 million years old. About 9 mi of the line.
Shale, sandstone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 5 mi of the line.
Limestone, dolostone. Age: Ordovician, 445 to 487 million years old. About 1 mi of the line.

A raindrop that lands in Manvel reaches Hudson Bay by way of the Turtle, the Red River of the North and the Nelson: about 940 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: Lake Winnipeg.
400 miles of the trip are on the Nelson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Manvel; river miles along the main stem, rounded.
Manvel has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about −3° in January. A normal year brings about 48 inches of snow; with the rain, that comes to about 22 inches of water.
On November 14 Manvel normally reaches 36° and falls to 18°. The record high is 65°, in 2025; the record low −3°, in 2002. The most rain on this date, 0.26 in, fell in 2005.
Normals 1991–2020 and records since 1965 at Grand Forks International Airport, 9 miles south. NOAA, through RCC-ACIS.
