North Smithfield’s center stands about 380 ft above sea level. Within three miles the land runs from 190 ft to 540 ft, a difference of 350 ft: rolling country. The highest named summit within 15 miles is Wood Hill, about 930 ft, 15 miles west-northwest.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 29×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

Granite. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Sandstone, graywacke. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Migmatite. Age: Neoproterozoic, 542 to 1,000 million years old. About 2 mi of the line.
Mica-schist, quartzite. Age: Neoproterozoic, 542 to 1,000 million years old. About 2 mi of the line.
Gneiss, amphibolite. Age: Neoproterozoic, 542 to 1,000 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 6 smaller units along the line are not listed.

A raindrop that lands in North Smithfield reaches Narragansett Bay and the Atlantic Ocean by way of the Blackstone, the Seekonk and the Providence: about 25 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of North Smithfield; river miles along the main stem, rounded.
North Smithfield has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 19° in January. A normal year brings about 62 inches of snow; with the rain, that comes to about 54 inches of water.
On November 14 North Smithfield normally reaches 50° and falls to 33°. The record high is 72°, in 1993; the record low 11°, in 1986. The most rain on this date, 2.03 in, fell in 2009.
Normals 1991–2020 and records since 1974 at North Foster 1 E, 12 miles southwest, 250 ft higher. NOAA, through RCC-ACIS.
