70° on Nov. 11, 2020, the hottest reading for this week of the year since 1949. Next is 66° in 1956.
Boonville’s center stands about 1,150 ft above sea level. Within three miles the land runs from 940 ft to 1,600 ft, a difference of 660 ft: hilly country. The highest named summit within 15 miles is Gomer Hill, about 2,140 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Trenton Group (limestone), from the Middle Ordovician, 459 to 471 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 19×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, shale. Age: Late Ordovician, 445 to 459 million years old. About 6 mi of the line.
Black-shale. Age: Middle Ordovician, 459 to 471 million years old. About 5 mi of the line.
Limestone. Age: Middle Ordovician, 459 to 471 million years old. About 4 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 4 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Limestone. Age: Middle Ordovician, 459 to 471 million years old. About 1 mi of the line.

Boonville straddles the St. Lawrence Divide. Rain on the south side runs to New York Harbor 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 Mill Creek and the Black River: about 90 river miles. From the lake it goes down the St. Lawrence to the Atlantic. One that lands on the south side reaches New York Harbor and the Atlantic Ocean by way of Lansing Kill, the Mohawk and the Hudson: about 310 river miles.

Boonville has a warm-summer humid continental climate. Summer afternoons average 75° in July; winter nights fall to about 8° in January. A normal year brings about 164 inches of snow; with the rain, that comes to about 58 inches of water.
On November 14 Boonville normally reaches 42° and falls to 26°. The record high is 61°, in 2010; the record low −1°, in 2019. The most rain on this date, 0.95 in, fell in 1961.
Normals 1991–2020 and records since 1949 at Boonville 4 SSW, 4 miles south-southwest, 400 ft higher. NOAA, through RCC-ACIS.
