74° on Nov. 11, 2020, the hottest reading for this week of the year since 1969. Next is 71° in 1989.
Romulus’s center stands about 720 ft above sea level. Within three miles the land runs from 530 ft to 780 ft, a difference of 250 ft: rolling country. The highest named summit within 15 miles is Butcher Hill, about 1,640 ft, 13 miles south.
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 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 26×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Late Devonian, 359 to 384 million years old. About 6 mi of the line.
Shale, limestone. Age: Middle Devonian, 384 to 388 million years old. About 5 mi of the line.
Shale. Age: Middle Devonian, 384 to 388 million years old. About 4 mi of the line.
Shale. Age: Middle Devonian, 384 to 394 million years old. About 4 mi of the line.
Limestone. Age: Early Devonian to Middle Devonian, 388 to 410 million years old. About 2 mi of the line.
Shale, siltstone. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

A raindrop that lands in Romulus reaches Lake Ontario by way of Cayuga Lake, the Seneca and the Oswego: about 90 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Lake on the way: Cayuga Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Romulus; river miles along the main stem, rounded.
Romulus has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 16° in January. A normal year brings about 57 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Romulus normally reaches 47° and falls to 32°. The record high is 65°, in 2005; the record low 14°, in 2019. The most rain on this date, 0.62 in, fell in 1972.
Normals 1991–2020 and records since 1969 at Geneva Research Farm, 13 miles northwest. NOAA, through RCC-ACIS.
