79° on Nov. 15, 1993, the hottest reading for this week of the year since 1865. Next is 77° in 1973.
Yardville’s center stands about 100 ft above sea level. Within three miles the land runs from 0 ft to 160 ft, a difference of 160 ft: gently rolling country. The highest named summit within 15 miles is Baldpate Mountain, about 550 ft, 15 miles northwest.
Under the town center the state geologic map shows Merchantville Formation (sand), from the Late Cretaceous, 72 to 84 million years old.
The section below crosses 16 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 53×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, clay. Age: Pleistocene, less than 2.6 million years old. About 4 mi of the line.
Sand. Age: Late Cretaceous, 72 to 84 million years old. About 3 mi of the line.
Sand. Age: Late Cretaceous, 84 to 87 million years old. About 2 mi of the line.
Sand. Age: Miocene, 5.3 to 23 million years old. About 2 mi of the line.
Sand. Age: Late Cretaceous, 72 to 84 million years old. About 2 mi of the line.
Clay, silt. Age: Late Cretaceous, 72 to 84 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 10 smaller units along the line are not listed.

A raindrop that lands in Yardville reaches Delaware Bay and the Atlantic Ocean by way of Crosswicks Creek and the Delaware: about 100 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Yardville; river miles along the main stem, rounded.
Yardville has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 24° in January. A normal year brings about 27 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Yardville normally reaches 55° and falls to 37°. The record high is 72°, in 1993; the record low 16°, in 1986. The most rain on this date, 1.89 in, fell in 1972.
Normals 1991–2020 and records since 1865 from the Trenton Area threaded record (Trenton-Mercer Airport, 10 miles northwest). NOAA, through RCC-ACIS.
