St. Regis Falls’s center stands about 1,320 ft above sea level. Within three miles the land runs from 990 ft to 1,670 ft, a difference of 680 ft: hilly country. The highest named summit within 15 miles is Rice Mountain, about 2,510 ft, 14 miles southeast.
Under the town center the state geologic map shows Interlayered amphibolite and granitic, charnockitic, mangeritic, or syenitic gneiss (amphibolite, gneiss), from the Mesoproterozoic, 1 to 1.6 billion 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 10×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Amphibolite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 8 mi of the line.
Sandstone. Age: Cambrian, 487 to 497 million years old. About 7 mi of the line.
Charnockite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 4 mi of the line.
Dolostone. Age: Cambrian to Early Ordovician, 471 to 542 million years old. About 0.5 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.3 mi of the line.

A raindrop that lands in St. Regis Falls reaches the St. Lawrence River by way of the Saint Regis and the Saint Lawrence: about 45 river miles. The St. Lawrence carries it on to the Atlantic.

St. Regis Falls has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 6° in January. A normal year brings about 98 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 St. Regis Falls normally reaches 43° and falls to 28°. The record high is 66°, in 2005; the record low 0°, in 2019. The most rain on this date, 0.59 in, fell in 2015.
