Narragansett Pier’s center stands barely above sea level. Within three miles the land runs from 0 ft to 170 ft, a difference of 170 ft: gently rolling country. Open water lies within three miles. The highest named summit within 15 miles is Pine Hill, about 590 ft, 13 miles northwest.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 46×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss, amphibolite. Age: Neoproterozoic, 542 to 1,000 million years old. About 8 mi of the line.
Granite. Age: Late Devonian, 366 to 380 million years old. About 2 mi of the line.
Leucocratic-granitic. Age: Permian, 271 to 275 million years old. About 2 mi of the line.

A raindrop that lands in Narragansett Pier reaches Narragansett Bay and the Atlantic Ocean by way of Dead Man Brook, Crooked Brook and the Pettaquamscutt: about 3 river miles.

Narragansett Pier has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 21° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 53 inches of water.
On November 14 Narragansett Pier normally reaches 55° and falls to 34°. The record high is 71°, in 1993; the record low 12°, in 1905. The most rain on this date, 1.73 in, fell in 1972.
