67° on Nov. 11, 2020, the hottest reading for this week of the year since 1965. Next is 66° in 2022.
Waldoboro’s center stands about 80 ft above sea level. Within three miles the land runs from 10 ft to 330 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is Ragged Mountain, about 1,300 ft, 14 miles northeast.
Under the town center the state geologic map shows Devonian granite (muscovite accessory mineral), from the Devonian, 359 to 422 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 46×. 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: Devonian, 359 to 422 million years old. About 8 mi of the line.
Sandstone, limestone. Age: Ordovician to Devonian, 359 to 487 million years old. About 6 mi of the line.
Schist. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 1 mi of the line.

A raindrop that lands in Waldoboro reaches the Atlantic Ocean by way of the Medomak: about 1 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Waldoboro; river miles along the main stem, rounded.
Waldoboro has a warm-summer humid continental climate. Summer afternoons average 78° in July; winter nights fall to about 15° in January. A normal year brings about 79 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Waldoboro normally reaches 46° and falls to 33°. The record high is 62°, in 1973; the record low 11°, in 2019. The most rain on this date, 1.03 in, fell in 2006.
Normals 1991–2020 and records since 1965 at Newcastle, 9 miles west-southwest, 130 ft higher. NOAA, through RCC-ACIS.
