10° on Nov. 12, 2019, the coldest reading for this week of the year since 1987. Next is 13° in 2018.
Wildwood’s center stands about 800 ft above sea level. Within three miles the land runs from 490 ft to 850 ft, a difference of 360 ft: rolling country.
Under the town center the state geologic map shows Osagean Series (limestone), from the Carboniferous, 324 to 359 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 41×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 13 mi of the line.
Limestone. Age: Middle Ordovician, 459 to 471 million years old. About 4 mi of the line.
Limestone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 2 mi of the line.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Dolostone, limestone, shale. Age: Middle Ordovician, 459 to 471 million years old. About 1 mi of the line.
Dolostone, limestone. Age: Ordovician, 445 to 487 million years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Wildwood reaches the Gulf of America by way of Hamilton Creek, the Meramec and the Mississippi: about 1,170 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wildwood; river miles along the main stem, rounded.
Wildwood has a hot-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 22° in January. About 40 inches of rain fall in a normal year.
On November 14 Wildwood normally reaches 57° and falls to 35°. The record high is 80°, in 2025; the record low 13°, in 2018. The most rain on this date, 2.08 in, fell in 1993.
Normals 1991–2020 and records since 1987 at St Louis Spirit Of St Louis Airport, 6 miles north, 340 ft lower. NOAA, through RCC-ACIS.
