Tiverton’s center stands barely above sea level. Within three miles the land runs from 0 ft to 290 ft, a difference of 290 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Copicut Hill, about 360 ft, 10 miles northeast.
The section below crosses 5 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.
Granite. Age: Neoproterozoic, 600 to 601 million years old. About 6 mi of the line.
Granite. Age: Neoproterozoic, 542 to 1,000 million years old. About 4 mi of the line.
Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Gneiss, schist, amphibolite. Age: Neoproterozoic, 542 to 1,000 million years old. About 1 mi of the line.
Conglomerate. Age: Carboniferous, 299 to 324 million years old. About 0.3 mi of the line.

A raindrop that lands in Tiverton reaches Narragansett Bay and the Atlantic Ocean by way of Borden Brook and Almy Brook: about 5 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tiverton; river miles along the main stem, rounded.
Tiverton has a hot-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 24° in January. About 42 inches of rain fall in a normal year.
On November 14 Tiverton normally reaches 53° and falls to 38°. The record high is 67°, in 2005; the record low 20°, in 2019. The most rain on this date, 0.64 in, fell in 2000.
Normals 1991–2020 and records since 1996 at Newport State Airport, 8 miles south-southwest, 140 ft higher. NOAA, through RCC-ACIS.
