74° on Nov. 11, 2020, the hottest reading for this week of the year since 1963. Next is 67° in 2008.
Hamlin’s center stands about 710 ft above sea level. Within three miles the land runs from 420 ft to 840 ft, a difference of 420 ft: hilly country. The highest named summit within 15 miles is Moose Hill, about 1,040 ft, 8 miles west.
Under the town center the state geologic map shows Silurian - Ordovician Carys Mills Formation (siltstone, limestone), from the Late Ordovician to Silurian, 434 to 459 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 25×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, limestone. Age: Late Ordovician to Silurian, 434 to 459 million years old. About 8 mi of the line.
Mudstone. Age: Silurian, 422 to 445 million years old. About 4 mi of the line.
Mudstone, sandstone. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Sandstone, mudstone. Age: Silurian to Devonian, 359 to 445 million years old. About 1 mi of the line.
Mudstone, sandstone. Age: Ordovician, 445 to 487 million years old. About 1 mi of the line.
Sandstone, conglomerate. Age: Silurian, 422 to 445 million years old. About 0.9 mi of the line.

A raindrop that lands in Hamlin reaches the Bay of Fundy and the Atlantic Ocean by way of Martin Brook and the Saint John: about 220 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hamlin; river miles along the main stem, rounded.
Hamlin has a warm-summer humid continental climate. Summer afternoons average 76° in July; winter nights fall to about −5° in February. A normal year brings about 97 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Hamlin normally reaches 40° and falls to 25°. The record high is 54°, in 1992; the record low −1°, in 2019. The most rain on this date, 0.95 in, fell in 2003.
Normals 1991–2020 and records since 1963 at Van Buren 2, 7 miles north-northwest, 250 ft lower. NOAA, through RCC-ACIS.
