Hainesport’s center stands about 40 ft above sea level. Within three miles the land runs from 0 ft to 100 ft, a difference of 100 ft: gently rolling country. The highest named summit within 15 miles is Mount Holly, about 230 ft, 2 miles east-northeast.
The section below crosses 14 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.

From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 8 smaller units along the line are not listed.

A raindrop that lands in Hainesport reaches Delaware Bay and the Atlantic Ocean by way of South Branch Rancocas Creek, Rancocas Creek and the Delaware: about 90 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hainesport; river miles along the main stem, rounded.
Hainesport has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 23° in January. A normal year brings about 25 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Hainesport normally reaches 54° and falls to 34°. The record high is 66°, in 2005; the record low 18°, in 2019. The most rain on this date, 0.85 in, fell in 2008.
Normals 1991–2020 and records since 1993 at Philadelphia/Mt. Holly Wfo, 2 miles north-northeast. NOAA, through RCC-ACIS.
