74° on Nov. 11, 2020, the hottest reading for this week of the year since 1973. Next is 74° in 2022.
Newfields’s center stands about 80 ft above sea level. Within three miles the land runs from 0 ft to 260 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Mount Pawtuckaway, about 990 ft, 14 miles west-northwest.
Under the town center the state geologic map shows Merrimack Group, Kittery Formation (metasandstone, phyllite), from the Ordovician to Silurian, 422 to 487 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 45×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Phyllite, quartzite, mica-schist. Age: Ordovician to Silurian, 422 to 487 million years old. About 6 mi of the line.
Metasandstone, phyllite. Age: Ordovician to Silurian, 422 to 487 million years old. About 4 mi of the line.
Granite. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.
Schist, gneiss, quartzite. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 3 mi of the line.
Diorite, gabbro. Age: Early Devonian, 394 to 422 million years old. About 2 mi of the line.
Granofels, biotite-schist. Age: Ordovician to Silurian, 422 to 487 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 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 Newfields reaches the Atlantic Ocean by way of the Piscassic, the Pawtuckaway and the Piscataqua: about 20 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Newfields; river miles along the main stem, rounded.
Newfields 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 65 inches of snow; with the rain, that comes to about 51 inches of water.
On November 14 Newfields normally reaches 49° and falls to 32°. The record high is 71°, in 1989; the record low 10°, in 1986. The most rain on this date, 1.90 in, fell in 2006.
Normals 1991–2020 and records since 1973 at Greenland, 6 miles east. NOAA, through RCC-ACIS.
