Freeport’s center stands about 160 ft above sea level. Within three miles the land runs from 10 ft to 300 ft, a difference of 290 ft: rolling country. The highest named summit within 15 miles is Adams Hill, about 630 ft, 14 miles west.
Under the town center the state geologic map shows Silurian - Ordovician Vassalboro Formation (sandstone), from the Late Ordovician to Silurian, 428 to 459 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 49×. 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.
Sandstone. Age: Late Ordovician to Silurian, 428 to 459 million years old. About 4 mi of the line.
Felsic-volcanic, mafic-volcanic. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 3 mi of the line.
Slate. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 2 mi of the line.

A raindrop that lands in Freeport reaches the Atlantic Ocean by way of the Harraseeket: about 4 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Freeport; river miles along the main stem, rounded.
Freeport has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 14° in January. A normal year brings about 84 inches of snow; with the rain, that comes to about 50 inches of water.
On November 14 Freeport normally reaches 47° and falls to 32°. The record high is 63°, in 2011; the record low 12°, in 2019. The most rain on this date, 4.20 in, fell in 2009.
Normals 1991–2020 and records since 1995 at Gray, 8 miles west-northwest, 220 ft higher. NOAA, through RCC-ACIS.
