Dublin’s center stands about 1,500 ft above sea level. Within three miles the land runs from 990 ft to 2,240 ft, a difference of 1,250 ft: steep hill country. The highest named summit within 15 miles is Monadnock Mountain, about 3,130 ft, 4 miles southwest.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 10×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granodiorite. Age: Early Devonian, 394 to 422 million years old. About 9 mi of the line.
Metasedimentary. Age: Early Devonian, 394 to 422 million years old. About 4 mi of the line.
Metaclastic. Age: Early Devonian, 394 to 422 million years old. About 3 mi of the line.
Pelitic-schist, metasandstone. Age: Silurian, 434 to 445 million years old. About 3 mi of the line.
Quartz-diorite, tonalite, granodiorite. Age: Early Devonian, 394 to 422 million years old. About 2 mi of the line.
Granite. Age: Late Devonian, 359 to 384 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. 2 smaller units along the line are not listed.

A raindrop that lands in Dublin reaches the Atlantic Ocean by way of Mills Brook, Stanley Brook, Nubanusit Brook, the Contoocook and the Merrimack: about 170 river miles.
100 miles of the trip are on the Merrimack.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Dublin; river miles along the main stem, rounded.
Dublin has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 10° in January. A normal year brings about 60 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Dublin normally reaches 47° and falls to 27°. The record high is 68°, in 1989; the record low 6°, in 1905. The most rain on this date, 1.61 in, fell in 1937.
Normals 1991–2020 and records since 1893 at Keene, 13 miles west, 990 ft lower. NOAA, through RCC-ACIS.
