74° on Nov. 13, 2022, the hottest reading for this week of the year since 1989. Next is 67° in 1989.
Kennebunkport’s center stands about 20 ft above sea level. Within three miles the land runs from 0 ft to 120 ft, a difference of 120 ft: gently rolling country. Open water lies within three miles. The highest named summit within 15 miles is Mount Agamenticus, about 690 ft, 14 miles southwest.
Under the town center the state geologic map shows Silurian - Precambrian Z Kittery Formation (metasandstone, phyllite), from the Neoproterozoic to Silurian, 422 to 1,000 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 55×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metasandstone, phyllite. Age: Neoproterozoic to Silurian, 422 to 1,000 million years old. About 9 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 4 mi of the line.
Gabbro, diorite, ultramafic. Age: Cretaceous, 66 to 145 million years old. About 1 mi of the line.
Granodiorite. Age: Devonian, 359 to 422 million years old. About 0.6 mi of the line.
Granite. Age: Carboniferous, 299 to 359 million years old. About 0.6 mi of the line.

A raindrop that lands in Kennebunkport reaches the Atlantic Ocean by way of Smith Brook and the Batson: about 1 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Kennebunkport; river miles along the main stem, rounded.
Kennebunkport has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 13° in January. A normal year brings about 49 inches of snow; with the rain, that comes to about 52 inches of water.
On November 14 Kennebunkport normally reaches 49° and falls to 30°. The record high is 62°, in 2010; the record low 10°, in 2019. The most rain on this date, 1.11 in, fell in 2006.
