76° on Nov. 15, 1993, the hottest reading for this week of the year since 1925. Next is 75° in 2020.
Middleton’s center stands about 110 ft above sea level. Within three miles the land runs from 40 ft to 230 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Holt Hill, about 450 ft, 6 miles northwest.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 58×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

Diorite, gabbro. Age: Neoproterozoic, 542 to 1,000 million years old. About 5 mi of the line.
Tonalite, diorite. Age: Silurian, 425 to 435 million years old. About 3 mi of the line.
Gneiss. Age: Early Cambrian to Early Ordovician, 478 to 523 million years old. About 2 mi of the line.
Syenite. Age: Late Ordovician to Silurian, 428 to 459 million years old. About 1 mi of the line.
Granite, granodiorite. Age: Silurian, 422 to 445 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. 4 smaller units along the line are not listed.

A raindrop that lands in Middleton reaches the Atlantic Ocean by way of the Ipswich: about 20 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Middleton; river miles along the main stem, rounded.
Middleton has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 16° in January. A normal year brings about 48 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Middleton normally reaches 51° and falls to 32°. The record high is 70°, in 2016; the record low 13°, in 2019. The most rain on this date, 3.27 in, fell in 2009.
