Westfield’s center stands about 480 ft above sea level. Within three miles the land runs from 440 ft to 760 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is Mars Hill, about 1,730 ft, 6 miles east-southeast.
Under the town center the state geologic map shows Silurian - Ordovician Carys Mills Formation (siltstone, limestone), from the Late Ordovician to Silurian, 434 to 459 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 21×. 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. Age: Silurian, 422 to 445 million years old. About 3 mi of the line.
Mafic-volcanic, felsic-volcanic. Age: Ordovician to Silurian, 422 to 487 million years old. About 3 mi of the line.
Mudstone, sandstone. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Mudstone, sandstone. Age: Ordovician to Silurian, 422 to 487 million years old. About 0.9 mi of the line.
Ultramafic. Age: Neoproterozoic to Silurian, 422 to 1,000 million years old. About 0.3 mi of the line.

A raindrop that lands in Westfield reaches the Bay of Fundy and the Atlantic Ocean by way of Pretty Brook, Youngs Brook, the Prestile Stream and the Saint John: about 180 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Westfield; river miles along the main stem, rounded.
Westfield has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 3° in January. A normal year brings about 118 inches of snow; with the rain, that comes to about 41 inches of water.
On November 14 Westfield normally reaches 40° and falls to 26°. The record high is 60°, in 1951; the record low 3°, in 2019. The most rain on this date, 2.22 in, fell in 2006.
Normals 1991–2020 and records since 1939 from the Caribou Area threaded record (Caribou Wfo, 21 miles north-northwest, 140 ft higher). NOAA, through RCC-ACIS.
