92° on Nov. 12, 2023, the hottest reading for this week of the year since 1914. Next is 91° in 2024.
Rotonda’s center stands about 9 ft above sea level. Within three miles the land runs from 0 ft to 20 ft, a difference of 20 ft: nearly flat ground. Open water lies within three miles.
Under the town center the state geologic map shows Shelly sediments of Plio-Pleistocene age (sand, limestone), from the Late Pliocene to Pleistocene, less than 3.6 million years old.
The section below crosses 2 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: Late Pliocene to Pleistocene, less than 3.6 million years old. About 13 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 0.4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Rotonda reaches the Gulf of America by way of West Branch Coral Creek and Coral Creek: about 4 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Rotonda; river miles along the main stem, rounded.
Rotonda has a humid subtropical climate. Summer afternoons average 93° in August; winter nights fall to about 50° in January. About 53 inches of rain fall in a normal year.
On November 14 Rotonda normally reaches 82° and falls to 59°. The record high is 88°, in 2018; the record low 38°, in 1975. The most rain on this date, 1.70 in, fell in 1972.
Normals 1991–2020 and records since 1914 from the Punta Gorda Area threaded record (Punta Gorda Charlotte County Airport, 18 miles east). NOAA, through RCC-ACIS.
