Belfast’s center stands about 1,340 ft above sea level. Within three miles the land runs from 1,240 ft to 1,890 ft, a difference of 650 ft: hilly country. The highest named summit within 15 miles is Bliven Hill, about 2,320 ft, 13 miles southeast.
Under the town center the state geologic map shows Machias Formation (shale, siltstone, sandstone), from the Late Devonian, 359 to 384 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 18×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, siltstone, sandstone. Age: Late Devonian, 359 to 384 million years old. About 18 mi of the line.
Shale, sandstone. Age: Late Devonian, 359 to 384 million years old. About 6 mi of the line.

A raindrop that lands in Belfast reaches Lake Ontario by way of the Genesee: about 120 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Belfast; river miles along the main stem, rounded.
Belfast has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 13° in January. A normal year brings about 72 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Belfast normally reaches 48° and falls to 29°. The record high is 71°, in 1902; the record low −2°, in 1905. The most rain on this date, 0.90 in, fell in 1972.
Normals 1991–2020 and records since 1893 at Angelica, 5 miles east-southeast, 140 ft higher. NOAA, through RCC-ACIS.
