85° on Nov. 15, 1993, the hottest reading for this week of the year since 1893. Next is 83° in 1955.
Poquoson’s center stands barely above sea level. Within three miles the land runs from 0 ft to 40 ft, a difference of 40 ft: nearly flat ground. Open water lies within three miles.
The section below crosses 5 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.

Sand, silt. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.

Rain that falls on Poquoson runs straight into Chesapeake Bay and the Atlantic Ocean.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Poquoson; river miles along the main stem, rounded.
Poquoson has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 32° in January. About 48 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Poquoson normally reaches 61° and falls to 42°. The record high is 79°, in 1993; the record low 28°, in 1986. The most rain on this date, 1.32 in, fell in 1908.
