14° on Nov. 17, 1959, the coldest reading for this week of the year since 1938. Next is 14° in 2019.
Catlin’s center stands about 1,620 ft above sea level. Within three miles the land runs from 890 ft to 1,880 ft, a difference of 990 ft: steep hill country. The highest named summit within 15 miles is Irish Hill, about 2,020 ft, 13 miles east-northeast.
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 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 15×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

Catlin straddles the St. Lawrence Divide. Rain on the east side runs to Lake Ontario; most of the rest goes to Chesapeake Bay and the Atlantic Ocean.
From the center of town, a raindrop reaches Chesapeake Bay and the Atlantic Ocean by way of Sing Sing Creek, the Chemung and the Susquehanna: about 340 river miles. One that lands on the east side reaches Lake Ontario by way of Catharine Creek, L'Hommedieu Creek, the Seneca and the Oswego: about 140 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
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 Catlin; river miles along the main stem, rounded.
Catlin 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 Catlin 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.
