72° on Nov. 16, 1953, the hottest reading for this week of the year since 1893. Next is 71° in 2022.
Tustin’s center stands about 750 ft above sea level. Within three miles the land runs from 730 ft to 820 ft, a difference of 90 ft: gently rolling country. The highest named summit within 15 miles is Mount Morris, about 1,180 ft, 15 miles west-southwest.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 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 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.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 23 mi of the line.
Sandstone. Age: Ordovician, 445 to 487 million years old. About 1 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 0.5 mi of the line.

A raindrop that lands in Tustin reaches Lake Michigan by way of Lake Winneconne, the Wolf River and the Fox River: about 90 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lakes on the way: Lake Winnebago 6124, Lake Winneconne and Lake Butte des Morts.

Tustin has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 10° in January. A normal year brings about 39 inches of snow; with the rain, that comes to about 33 inches of water.
On November 14 Tustin normally reaches 45° and falls to 30°. The record high is 68°, in 1999; the record low 3°, in 1916. The most rain on this date, 0.79 in, fell in 1956.
Normals 1991–2020 and records since 1893 at Oshkosh, 19 miles east-southeast. NOAA, through RCC-ACIS.
