74° on Nov. 11, 2020, the hottest reading for this week of the year since 1941. Next is 70° in 1956.
Ellicottville’s center stands about 1,560 ft above sea level. Within three miles the land runs from 1,500 ft to 2,340 ft, a difference of 840 ft: hilly country. The highest named summit within 15 miles is Shutts Hill, about 2,460 ft, 9 miles west-southwest.
Under the town center the state geologic map shows Conneaut Group, undivided (shale, sandstone), from the Late Devonian, 359 to 384 million years old.
The section below crosses 3 rock units mapped at the surface.

Shale, sandstone. Age: Late Devonian, 359 to 384 million years old. About 20 mi of the line.

Ellicottville straddles the St. Lawrence Divide. Rain on the northwest side runs to Lake Erie; most of the rest goes to the Gulf of America.
From the center of town, a raindrop reaches the Gulf of America by way of Great Valley Creek, Wrights Creek, the Allegheny, the Ohio and the Mississippi: about 2,200 river miles. One that lands on the northwest side reaches Lake Erie by way of Mansfield Creek, South Branch Cattaraugus Creek and Cattaraugus Creek: about 45 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lake on the way: Allegheny Reservoir.
970 miles of the trip are on the Ohio.

Ellicottville has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 13° in January. A normal year brings about 133 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Ellicottville normally reaches 47° and falls to 29°. The record high is 67°, in 2010; the record low 11°, in 1942. The most rain on this date, 1.10 in, fell in 1972.
