74° on Nov. 11, 2024, the hottest reading for this week of the year since 1978. Next is 72° in 1993.
New London’s center stands about 490 ft above sea level. Within three miles the land runs from 250 ft to 570 ft, a difference of 320 ft: rolling country.
Under the town center the state geologic map shows "Glenarm Wissahickon" formation (mica-schist), from the Paleozoic, 252 to 542 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 29×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mica-schist. Age: Paleozoic, 252 to 542 million years old. About 11 mi of the line.
Mica-schist, quartzite. Age: Paleozoic, 252 to 542 million years old. About 6 mi of the line.
Sand, clay, silt. Age: Early Cretaceous, 100 to 145 million years old. About 2 mi of the line.
Schist, gneiss. Age: Paleozoic, 252 to 542 million years old. About 2 mi of the line.
Schist, phyllite. Age: Paleozoic, 252 to 542 million years old. About 1 mi of the line.
Muscovite-schist. Age: Proterozoic, 542 to 2,500 million years old. About 0.8 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 New London reaches Chesapeake Bay and the Atlantic Ocean by way of Hodgson Run, Big Elk Creek and the Elk River: about 35 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of New London; river miles along the main stem, rounded.
New London has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 22° in January. A normal year brings about 18 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 New London normally reaches 54° and falls to 33°. The record high is 72°, in 1993; the record low 15°, in 2022. The most rain on this date, 0.92 in, fell in 1995.
Normals 1991–2020 and records since 1978 at Octoraro Lake, 9 miles west, 230 ft lower. NOAA, through RCC-ACIS.
