79° on Nov. 14, 1999, the hottest reading for this week of the year since 1971. Next is 72° in 2001.
Belfast’s center stands about 1,480 ft above sea level. Within three miles the land runs from 1,400 ft to 1,500 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Sioux Quartzite (quartzite, mudstone), from the Paleoproterozoic, 1.6 to 2 billion 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 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.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 14 mi of the line.
Quartzite, mudstone. Age: Paleoproterozoic, 1.6 to 2 billion years old. About 10 mi of the line.

A raindrop that lands in Belfast reaches the Gulf of America by way of the Des Moines and the Mississippi: about 1,820 river miles.
Lakes on the way: Roberts Creek and Big Creek Pounding Area.
1,330 miles of the trip are on the Mississippi.
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 82° in July; winter nights fall to about 5° in January. A normal year brings about 45 inches of snow; with the rain, that comes to about 30 inches of water.
On November 14 Belfast normally reaches 42° and falls to 24°. The record high is 79°, in 1999; the record low −4°, in 1986. The most rain on this date, 0.30 in, fell in 2024.
Normals 1991–2020 and records since 1971 at Worthington 2 NNE, 17 miles south-southwest. NOAA, through RCC-ACIS.
