9° on Nov. 13, 2019, the coldest reading for this week of the year since 1909. Next is 14° in 1996.
Savona’s center stands about 1,050 ft above sea level. Within three miles the land runs from 1,020 ft to 1,850 ft, a difference of 830 ft: hilly country. The highest named summit within 15 miles is Oak Hill, about 2,200 ft, 13 miles west.
Under the town center the state geologic map shows Gardeau Formation (shale), from the Late Devonian, 359 to 384 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 17×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Late Devonian, 359 to 384 million years old. About 9 mi of the line.

A raindrop that lands in Savona reaches Chesapeake Bay and the Atlantic Ocean by way of Mud Creek, the Cohocton, the Chemung and the Susquehanna: about 350 river miles.
Lake on the way: Lake Aldred.
250 miles of the trip are on the Susquehanna.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Savona; river miles along the main stem, rounded.
Savona has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 12° in January. A normal year brings about 53 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Savona normally reaches 46° and falls to 27°. The record high is 65°, in 1994; the record low 9°, in 2019. The most rain on this date, 0.87 in, fell in 1937.
Normals 1991–2020 and records since 1909 at Corning, 13 miles southeast. NOAA, through RCC-ACIS.
