74° on Nov. 11, 2020, the hottest reading for this week of the year since 1917. Next is 68° in 2012.
Meddybemps’s center stands about 180 ft above sea level. Within three miles the land runs from 160 ft to 470 ft, a difference of 310 ft: rolling country. The highest named summit within 15 miles is Harmon Mountain, about 750 ft, 15 miles west.
Under the town center the state geologic map shows Devonian gabbro/diorite/ultramafic rocks (gabbro, diorite, ultramafic), from the Devonian, 359 to 422 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 37×. 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: Devonian, 359 to 422 million years old. About 9 mi of the line.
Sandstone. Age: Early Ordovician to Late Ordovician, 445 to 487 million years old. About 3 mi of the line.
Shale. Age: Silurian, 422 to 445 million years old. About 3 mi of the line.
Felsic-volcanic, mafic-volcanic. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Age: Devonian, 359 to 422 million years old. About 2 mi of the line.
Felsic-volcanic, mafic-volcanic. Age: Devonian, 359 to 422 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 5 smaller units along the line are not listed.

A raindrop that lands in Meddybemps reaches the Atlantic Ocean by way of Meddybemps Lake and the Dennys: about 20 river miles.
Lake on the way: Meddybemps Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Meddybemps; river miles along the main stem, rounded.
Meddybemps has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 13° in January. About 48 inches of rain fall in a normal year.
On November 14 Meddybemps normally reaches 46° and falls to 34°. The record high is 63°, in 2012; the record low 10°, in 1986. The most rain on this date, 1.85 in, fell in 1975.
Normals 1991–2020 and records since 1917 at Woodland, 8 miles north-northwest. NOAA, through RCC-ACIS.
