The Italy plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
78° on Nov. 11, 2020, the hottest reading for this week of the year since 1992. Next is 76° in 1994.
Italy’s center stands about 1,130 ft above sea level. Within three miles the land runs from 950 ft to 2,100 ft, a difference of 1,150 ft: steep hill country. The highest named summit within 15 miles is Gannett Hill, about 2,320 ft, 8 miles northwest.
Under the town center the state geologic map shows Beers Hill, Dunn Hill, Millport, and Moreland Shales; Grimes Siltstone, 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 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Italy reaches Lake Ontario by way of Canandaigua Lake, the Canandaigua Outlet, the Erie Canal, the Clyde, 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: Canandaigua Lake.

Italy has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 16° in January. A normal year brings about 55 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 Italy normally reaches 50° and falls to 32°. The record high is 69°, in 2010; the record low 15°, in 2019. The most rain on this date, 0.51 in, fell in 1997.
