Covington’s center stands about 1,110 ft above sea level. Within three miles the land runs from 930 ft to 1,290 ft, a difference of 360 ft: rolling country. The highest named summit within 15 miles is Oak Hill, about 1,740 ft, 11 miles south-southwest.
Under the town center the state geologic map shows Cashaqua and Middlesex Shales, from the Late Devonian, 359 to 384 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 16×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Covington reaches Lake Ontario by way of Pearl Creek, Oatka Creek and the Genesee: about 60 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Covington; river miles along the main stem, rounded.
Covington has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 15° in January. About 33 inches of rain fall in a normal year.
On November 14 Covington normally reaches 49° and falls to 32°. The record high is 73°, in 2011; the record low 15°, in 2019. The most rain on this date, 0.67 in, fell in 1972.
