The Ossipee plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
73° on Nov. 11, 2020, the hottest reading for this week of the year since 1926. Next is 70° in 2022.
Ossipee’s center stands about 680 ft above sea level. Within three miles the land runs from 480 ft to 1,250 ft, a difference of 770 ft: hilly country. The highest named summit within 15 miles is Mount Shaw, about 2,970 ft, 9 miles west-northwest.
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 11×. 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: Carboniferous, 299 to 359 million years old. About 9 mi of the line.
Metagraywacke. Age: Early Devonian, 410 to 414 million years old. About 4 mi of the line.
Mudstone, limestone. Age: Silurian to Devonian, 359 to 445 million years old. About 3 mi of the line.
Rhyolite, granite. Age: Cretaceous, 66 to 145 million years old. About 3 mi of the line.
Age: Cretaceous, 66 to 145 million years old. About 2 mi of the line.
Tonalite. Age: Early Devonian, 394 to 422 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. 3 smaller units along the line are not listed.

A raindrop that lands in Ossipee reaches the Atlantic Ocean by way of the Beech, the Pine River, the Ossipee and the Saco: about 75 river miles.
Lake on the way: Ossipee Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ossipee; river miles along the main stem, rounded.
Ossipee has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 12° in January. A normal year brings about 62 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Ossipee normally reaches 48° and falls to 30°. The record high is 62°, in 2010; the record low 8°, in 2019. The most rain on this date, 3.40 in, fell in 1937.
