High Falls’s center stands about 250 ft above sea level. Within three miles the land runs from 90 ft to 1,030 ft, a difference of 940 ft: steep hill country. The highest named summit within 15 miles is High Point, about 3,090 ft, 11 miles northwest.
Under the town center the state geologic map shows Undifferentiated Lower Devonian and Silurian rocks, from the Silurian to Early Devonian, 394 to 445 million years old.
The section below crosses 6 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.
Shale, sandstone, conglomerate. Age: Silurian, 422 to 428 million years old. About 12 mi of the line.
Age: Silurian to Early Devonian, 394 to 445 million years old. About 6 mi of the line.
Graywacke, shale. Age: Middle Ordovician, 459 to 471 million years old. About 2 mi of the line.
Limestone. Age: Silurian to Early Devonian, 394 to 428 million years old. About 2 mi of the line.

A raindrop that lands in High Falls reaches New York Harbor and the Atlantic Ocean by way of Rondout Creek and the Hudson: about 110 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of High Falls; river miles along the main stem, rounded.
High Falls 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 High Falls 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, 18 miles southeast). NOAA, through RCC-ACIS.
