73° on Nov. 12, 2022, the hottest reading for this week of the year since 1871. Next is 72° in 1896.
Falmouth Foreside’s center stands about 120 ft above sea level. Within three miles the land runs from 0 ft to 240 ft, a difference of 240 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Adams Hill, about 630 ft, 14 miles northwest.
Under the town center the state geologic map shows Ordovician - Precambrian Z Cushing Formation (felsic-volcanic, mafic-volcanic), from the Neoproterozoic to Ordovician, 445 to 1,000 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 40×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granite. Age: Carboniferous, 299 to 359 million years old. About 6 mi of the line.
Sandstone. Age: Late Ordovician to Silurian, 428 to 459 million years old. About 4 mi of the line.
Schist, slate. Age: Silurian, 428 to 445 million years old. About 2 mi of the line.
Felsic-volcanic, mafic-volcanic. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 0.7 mi of the line.
Slate. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 0.3 mi of the line.
Mudstone, sandstone. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 0.3 mi of the line.

A raindrop that lands in Falmouth Foreside reaches the Atlantic Ocean by way of Norton Brook and Mill Creek: about 1 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Falmouth Foreside; river miles along the main stem, rounded.
Falmouth Foreside has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 16° in January. A normal year brings about 69 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Falmouth Foreside normally reaches 49° and falls to 32°. The record high is 69°, in 1973; the record low 12°, in 1986. The most rain on this date, 5.03 in, fell in 2009.
