Montgomery’s center stands about 380 ft above sea level. Within three miles the land runs from 340 ft to 660 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is High Point, about 2,250 ft, 13 miles north-northwest.
Under the town center the state geologic map shows Normanskill Formation (shale), from the Middle Ordovician, 459 to 471 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Middle Ordovician, 459 to 471 million years old. About 13 mi of the line.
Graywacke, shale. Age: Middle Ordovician, 459 to 471 million years old. About 8 mi of the line.
Shale, siltstone, sandstone. Age: Middle Devonian, 384 to 394 million years old. About 1 mi of the line.
Age: Silurian to Early Devonian, 394 to 445 million years old. About 0.8 mi of the line.

A raindrop that lands in Montgomery reaches New York Harbor and the Atlantic Ocean by way of the Hudson: about 130 river miles.
90 miles of the trip are on the Hudson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Montgomery; river miles along the main stem, rounded.
Montgomery has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 18° in January. About 42 inches of rain fall in a normal year.
On November 14 Montgomery normally reaches 52° and falls to 32°. The record high is 72°, in 1973; the record low 13°, in 1986. The most rain on this date, 2.01 in, fell in 1972.
Normals 1991–2020 and records since 1931 from the Poughkeepsie Area threaded record (Poughkeepsie/Hudson Valley Regional Airport, 20 miles east-northeast, 230 ft lower). NOAA, through RCC-ACIS.
