Westford’s center stands about 1,130 ft above sea level. Within three miles the land runs from 1,090 ft to 1,160 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Upper Cambrian (sandstone, siltstone, shale), from the Cambrian, 487 to 497 million years old.
The section below crosses 2 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, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 20 mi of the line.
Sandstone, siltstone, shale. Age: Middle Cambrian to Cambrian, 487 to 521 million years old. About 4 mi of the line.

A raindrop that lands in Westford reaches the Gulf of America by way of Perch Creek, the Watonwan, the Blue Earth, the Minnesota and the Mississippi: about 1,990 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Westford; river miles along the main stem, rounded.
Westford has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 6° in January. A normal year brings about 47 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Westford normally reaches 43° and falls to 26°. The record high is 80°, in 1999; the record low −7°, in 1940. The most rain on this date, 1.26 in, fell in 1909.
