71° on Nov. 11, 2020, the hottest reading for this week of the year since 1993. Next is 70° in 2022.
Brunswick’s center stands about 70 ft above sea level. Within three miles the land runs from 10 ft to 220 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Whitten Hill, about 640 ft, 13 miles north.
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 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 57×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Felsic-volcanic, mafic-volcanic. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 9 mi of the line.
Sandstone. Age: Late Ordovician to Silurian, 428 to 459 million years old. About 9 mi of the line.
Slate. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 3 mi of the line.

Rain that falls on Brunswick runs only a short way, about 2 miles, to the Atlantic Ocean.

Brunswick has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 7° in January. A normal year brings about 78 inches of snow; with the rain, that comes to about 50 inches of water.
On November 14 Brunswick normally reaches 46° and falls to 27°. The record high is 64°, in 2010; the record low 6°, in 2019. The most rain on this date, 1.02 in, fell in 2018.
