Springfield’s center stands about 1,430 ft above sea level. Within three miles the land runs from 1,040 ft to 2,080 ft, a difference of 1,040 ft: steep hill country. The highest named summit within 15 miles is Mount Cardigan, about 3,110 ft, 13 miles north-northeast.
Under the town center the state geologic map shows Bethlehem Granodiorite, from the Early Devonian, 394 to 422 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Springfield reaches Long Island Sound and the Atlantic Ocean by way of Grove Brook, Bog Brook, Stocker Brook, the North Branch Sugar, the Sugar and the Connecticut: about 230 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Springfield; river miles along the main stem, rounded.
Springfield has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 9° in January. A normal year brings about 66 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Springfield normally reaches 46° and falls to 27°. The record high is 62°, in 2010; the record low 8°, in 2019. The most rain on this date, 2.64 in, fell in 1937.
