Middleport’s center stands about 520 ft above sea level. Within three miles the land runs from 390 ft to 650 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Nichols Hill, about 740 ft, 11 miles southeast.
Under the town center the state geologic map shows Medina Group (sandstone, shale), from the Silurian, 434 to 445 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 37×. 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 Ordovician, 445 to 459 million years old. About 11 mi of the line.
Shale. Age: Silurian, 422 to 428 million years old. About 7 mi of the line.
Dolostone. Age: Silurian, 425 to 434 million years old. About 4 mi of the line.
Sandstone, shale. Age: Silurian, 434 to 445 million years old. About 1 mi of the line.
Shale. Age: Silurian, 428 to 445 million years old. About 0.9 mi of the line.

A raindrop that lands in Middleport reaches Lake Ontario by way of Jeddo Creek and Johnson Creek: about 25 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Middleport; river miles along the main stem, rounded.
Middleport has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 18° in January. About 38 inches of rain fall in a normal year.
