70° on Nov. 16, 1953, the hottest reading for this week of the year since 1896. Next is 69° in 1964.
Waldwick’s center stands about 1,090 ft above sea level. Within three miles the land runs from 910 ft to 1,170 ft, a difference of 260 ft: rolling country.
Under the town center the state geologic map shows Sinnipee Group (dolostone), from the Ordovician, 445 to 487 million years old.
The section below crosses 2 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.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 18 mi of the line.
Sandstone. Age: Ordovician, 445 to 487 million years old. About 6 mi of the line.

A raindrop that lands in Waldwick reaches the Gulf of America by way of the Yellowstone, the East Branch Pecatonica, the Pecatonica, the Rock River and the Mississippi: about 1,750 river miles.
1,450 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Waldwick; river miles along the main stem, rounded.
Waldwick has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 9° in January. A normal year brings about 41 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Waldwick normally reaches 45° and falls to 26°. The record high is 69°, in 1971; the record low −3°, in 1916. The most rain on this date, 0.80 in, fell in 2024.
