Odessa’s center stands about 1,070 ft above sea level. Within three miles the land runs from 470 ft to 1,770 ft, a difference of 1,300 ft: steep hill country. The highest named summit within 15 miles is Connecticut Hill, about 2,140 ft, 7 miles east-northeast.
Under the town center the state geologic map shows Sonyea Group (shale, siltstone), from the Late Devonian, 359 to 384 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. 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: Late Devonian, 359 to 384 million years old. About 11 mi of the line.
Shale, siltstone. Age: Late Devonian, 359 to 384 million years old. About 8 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 5 mi of the line.

A raindrop that lands in Odessa reaches Lake Ontario by way of Catlin Mill Creek, L'Hommedieu Creek, the Seneca and the Oswego: about 130 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Lakes on the way: Seneca Lake and Cayuga Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Odessa; river miles along the main stem, rounded.
Odessa has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 16° in January. About 32 inches of rain fall in a normal year.
On November 14 Odessa normally reaches 50° and falls to 30°. The record high is 69°, in 1945; the record low 17°, in 2014. The most rain on this date, 0.40 in, fell in 2011.
