72° on Nov. 11, 2020, the hottest reading for this week of the year since 1911. Next is 69° in 1956.
Tully’s center stands about 1,250 ft above sea level. Within three miles the land runs from 700 ft to 1,960 ft, a difference of 1,260 ft: steep hill country. The highest named summit within 15 miles is Truxton Hill, about 2,090 ft, 3 miles south-southeast.
Under the town center the state geologic map shows Moscow Formation (shale), from the Middle Devonian, 384 to 388 million years old.
The section below crosses 7 rock units mapped at the surface.

Shale. Age: Late Devonian, 359 to 384 million years old. About 11 mi of the line.
Black-shale. Age: Middle Devonian, 388 to 394 million years old. About 7 mi of the line.
Shale. Age: Middle Devonian, 384 to 388 million years old. About 3 mi of the line.
Shale. Age: Middle Devonian, 384 to 394 million years old. About 2 mi of the line.
Limestone. Age: Middle Devonian, 384 to 394 million years old. About 0.6 mi of the line.
Limestone. Age: Early Devonian to Middle Devonian, 388 to 410 million years old. About 0.5 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

Tully straddles the St. Lawrence Divide. Rain on the south side runs to Chesapeake Bay and the Atlantic Ocean; most of the rest goes to Lake Ontario.
From the center of town, a raindrop reaches Lake Ontario by way of Onondaga Creek, the Seneca and the Oswego: about 60 river miles. From the lake it goes down the St. Lawrence to the Atlantic. One that lands on the south side reaches Chesapeake Bay and the Atlantic Ocean by way of the West Branch Tioughnioga, the Tioughnioga, the Chenango and the Susquehanna: about 400 river miles.
Lake on the way: Onondaga Lake.

Tully has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 11° in January. About 48 inches of rain fall in a normal year.
On November 14 Tully normally reaches 45° and falls to 29°. The record high is 64°, in 1989; the record low 4°, in 2019. The most rain on this date, 1.09 in, fell in 1968.
