74° on Nov. 11, 2022, the hottest reading for this week of the year since 1951. Next is 71° in 2020.
Mio’s center stands about 1,020 ft above sea level. Within three miles the land runs from 930 ft to 1,280 ft, a difference of 350 ft: rolling country. The highest named summit within 15 miles is Mount Tom, about 1,510 ft, 6 miles north.
Under the town center the state geologic map shows Marshall Sandstone, from the Carboniferous, 324 to 359 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 39×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 10 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 9 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 5 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Mio reaches Lake Huron by way of the Au Sable: about 75 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Mio; river miles along the main stem, rounded.
Mio has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 9° in February. About 33 inches of rain fall in a normal year.
On November 14 Mio normally reaches 44° and falls to 27°. The record high is 65°, in 1953; the record low 3°, in 2019. The most rain on this date, 1.32 in, fell in 1957.
Normals 1991–2020 and records since 1951 at Lupton 1 S, 17 miles south-southeast, 110 ft lower. NOAA, through RCC-ACIS.
