74° on Nov. 11, 2020, the hottest reading for this week of the year since 1942. Next is 73° in 1956.
Candia’s center stands about 550 ft above sea level. Within three miles the land runs from 280 ft to 810 ft, a difference of 530 ft: hilly country. The highest named summit within 15 miles is Fort Mountain, about 1,400 ft, 9 miles north.
Under the town center the state geologic map shows Massabesic Gneiss Complex (gneiss, biotite-schist, granofels), from the Neoproterozoic, 542 to 1,000 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 27×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss, biotite-schist, granofels. Age: Neoproterozoic, 542 to 1,000 million years old. About 9 mi of the line.
Schist, granofels. Age: Ordovician to Silurian, 422 to 487 million years old. About 4 mi of the line.
Metagraywacke. Age: Early Devonian, 410 to 414 million years old. About 3 mi of the line.
Granite. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.
Metaclastic. Age: Silurian, 434 to 445 million years old. About 1 mi of the line.
Pelitic-schist, metasandstone. Age: Silurian, 434 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. 3 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Candia reaches the Atlantic Ocean by way of Moose Meadow Brook, Maple Falls Brook, Cohas Brook and the Merrimack: about 85 river miles.
65 miles of the trip are on the Merrimack.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Candia; river miles along the main stem, rounded.
Candia has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 13° in January. A normal year brings about 53 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Candia normally reaches 49° and falls to 31°. The record high is 67°, in 1959; the record low 10°, in 2001. The most rain on this date, 0.86 in, fell in 1975.
Normals 1991–2020 and records since 1942 at Massabesic Lake, 5 miles south-southwest, 300 ft lower. NOAA, through RCC-ACIS.
