70° on Nov. 12, 2005, the hottest reading for this week of the year since 1940. Next is 65° in 2001.
Newton’s center stands about 1,390 ft above sea level. Within three miles the land runs from 1,370 ft to 1,440 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Granitic intrusion, from the Neoarchean, 2.5 to 2.8 billion 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 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 9 mi of the line.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 7 mi of the line.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 5 mi of the line.
Tonalite, granodiorite, diorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 3 mi of the line.
Plutonic. Age: Archean. About 0.7 mi of the line.

Newton straddles the Laurentian Divide. Rain on the northwest side runs to Hudson Bay; most of the rest goes to the Gulf of America.
From the center of town, a raindrop reaches the Gulf of America by way of Bluff Creek, the Leaf, the Redeye, the Crow Wing and the Mississippi: about 2,050 river miles. One that lands on the northwest side reaches Hudson Bay by way of Willow Creek, the Otter Tail, the Red River of the North and the Nelson: about 1,300 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Newton; river miles along the main stem, rounded.
Newton has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about −2° in January. About 28 inches of rain fall in a normal year.
On November 14 Newton normally reaches 37° and falls to 22°. The record high is 63°, in 1981; the record low 6°, in 1965. The most rain on this date, 0.47 in, fell in 2024.
Normals 1991–2020 and records since 1940 at Ottertail, 12 miles west-southwest. NOAA, through RCC-ACIS.
