Center Ossipee’s center stands about 540 ft above sea level. Within three miles the land runs from 400 ft to 1,250 ft, a difference of 850 ft: hilly country. The highest named summit within 15 miles is Mount Shaw, about 2,970 ft, 6 miles west.
Under the town center the state geologic map shows Two-mica granite of the Sebago batholith and Effingham pluton of eastern New Hampshire, from the Carboniferous, 299 to 359 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 9×. 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: Early Cretaceous, 100 to 145 million years old. About 8 mi of the line.
Granite. Age: Carboniferous, 299 to 359 million years old. About 7 mi of the line.
Tonalite. Age: Early Devonian, 394 to 422 million years old. About 2 mi of the line.
Mudstone, limestone. Age: Silurian to Devonian, 359 to 445 million years old. About 2 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 2 mi of the line.
Rhyolite, granite. Age: Cretaceous, 66 to 145 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.

A raindrop that lands in Center Ossipee reaches the Atlantic Ocean by way of Folsom Brook, 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 Center Ossipee; river miles along the main stem, rounded.
Center Ossipee has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 7° in January. About 47 inches of rain fall in a normal year.
On November 14 Center Ossipee normally reaches 47° and falls to 26°. The record high is 63°, in 2016; the record low 4°, in 2019. The most rain on this date, 2.06 in, fell in 2009.
Normals 1991–2020 and records since 1996 at Fryeburg Eastern Slopes Regl Airport, 19 miles north-northeast. NOAA, through RCC-ACIS.
