Foxborough’s center stands about 290 ft above sea level. Within three miles the land runs from 160 ft to 420 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Great Blue Hill, about 630 ft, 12 miles north-northeast.
Under the town center the state geologic map shows Dedham Granite, from the Neoproterozoic, 615 to 645 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 42×. 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, graywacke. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Conglomerate, graywacke. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Granite. Age: Neoproterozoic, 615 to 645 million years old. About 4 mi of the line.
Syenite. Age: Neoproterozoic, 542 to 1,000 million years old. About 4 mi of the line.
Rhyolite. Age: Neoproterozoic, 599 to 605 million years old. About 1 mi of the line.
Conglomerate, arkose. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Foxborough reaches Narragansett Bay and the Atlantic Ocean by way of the Threemile and the Taunton: about 35 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Foxborough; river miles along the main stem, rounded.
Foxborough has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 18° in January. A normal year brings about 50 inches of snow; with the rain, that comes to about 52 inches of water.
On November 14 Foxborough normally reaches 52° and falls to 32°. The record high is 72°, in 1993; the record low 13°, in 1981. The most rain on this date, 1.29 in, fell in 1982.
Normals 1991–2020 and records since 1913 at Norton West, 6 miles southeast, 200 ft lower. NOAA, through RCC-ACIS.
