The West Haverstraw plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
77° on Nov. 11, 2020, the hottest reading for this week of the year since 1950. Next is 69° in 2022.
West Haverstraw’s center stands about 120 ft above sea level. Within three miles the land runs from 0 ft to 770 ft, a difference of 770 ft: hilly country. Open water lies within three miles. The highest named summit within 15 miles is Schunnemunk Mountain, about 1,540 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Brunswick Formation (sandstone), from the Late Triassic, 202 to 237 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 15×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mudstone, sandstone, arkose. Age: Late Triassic, 202 to 237 million years old. About 4 mi of the line.
Granite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Sandstone, siltstone, mudstone. Age: Late Triassic, 202 to 237 million years old. About 3 mi of the line.

Sandstone. Age: Late Triassic, 202 to 237 million years old. About 2 mi of the line.
Age: Mesoproterozoic, 1 to 1.6 billion 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. 3 smaller units along the line are not listed.

A raindrop that lands in West Haverstraw reaches New York Harbor and the Atlantic Ocean by way of the Hudson: about 40 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of West Haverstraw; river miles along the main stem, rounded.
West Haverstraw has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 17° in January. About 50 inches of rain fall in a normal year.
On November 14 West Haverstraw normally reaches 53° and falls to 32°. The record high is 68°, in 1964; the record low 17°, in 2019. The most rain on this date, 1.18 in, fell in 1955.
