90° on Nov. 11, 2015, the hottest reading for this week of the year since 1935. Next is 89° in 1948.
Hobe Sound’s center stands about 30 ft 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.
Under the town center the state geologic map shows Anastasia Formation (sand, limestone), from the Pleistocene, less than 2.6 million years old.
The section below crosses 4 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, limestone. Age: Pleistocene, less than 2.6 million years old. About 7 mi of the line.
Sand, limestone. Age: Late Pliocene to Pleistocene, less than 3.6 million years old. About 5 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 0.9 mi of the line.
Sand, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.4 mi of the line.

A raindrop that lands in Hobe Sound reaches the Atlantic Ocean by way of the Loxahatchee: about 10 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hobe Sound; river miles along the main stem, rounded.
Hobe Sound has a tropical rainforest climate. Summer afternoons average 91° in July; winter nights fall to about 56° in January. About 63 inches of rain fall in a normal year.
On November 14 Hobe Sound normally reaches 80° and falls to 65°. The record high is 88°, in 1948; the record low 43°, in 1975. The most rain on this date, 2.75 in, fell in 1954.
Normals 1991–2020 and records since 1935 at Stuart, 11 miles northwest. NOAA, through RCC-ACIS.
