−1° on Nov. 17, 1967, the coldest reading for this week of the year since 1868. Next is 0° in 1972.
Weare’s center stands about 640 ft above sea level. Within three miles the land runs from 420 ft to 1,150 ft, a difference of 730 ft: hilly country. The highest named summit within 15 miles is Crotched Mountain, about 2,050 ft, 10 miles southwest.
Under the town center the state geologic map shows Perry Mountain Formation, undivided (quartzite, metasedimentary), from the Silurian, 422 to 445 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 12×. 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: Late Devonian, 359 to 384 million years old. About 7 mi of the line.
Quartz-diorite, tonalite, granodiorite. Age: Early Devonian, 394 to 422 million years old. About 6 mi of the line.
Quartzite, metasedimentary. Age: Silurian, 422 to 445 million years old. About 4 mi of the line.
Pelitic-schist, metasandstone. Age: Silurian, 434 to 445 million years old. About 3 mi of the line.
Granodiorite. Age: Early Devonian, 394 to 422 million years old. About 3 mi of the line.
Metaclastic. Age: Silurian, 434 to 445 million years old. About 0.7 mi of the line.

A raindrop that lands in Weare reaches the Atlantic Ocean by way of Otter Brook, the Middle Branch Piscataquog, the South Branch Piscataquog, the Piscataquog and the Merrimack: about 90 river miles.
70 miles of the trip are on the Merrimack.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Weare; river miles along the main stem, rounded.
Weare has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 13° in January. A normal year brings about 68 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Weare normally reaches 49° and falls to 29°. The record high is 71°, in 1989; the record low 7°, in 1986. The most rain on this date, 1.92 in, fell in 2009.
Normals 1991–2020 and records since 1868 from the Concord Area threaded record (Concord Municipal Airport, 14 miles east-northeast, 300 ft lower). NOAA, through RCC-ACIS.
