6.67 inches of rain fell in two days, the most for this week of the year since records began in 1911. The next wettest, 5.04 inches, fell in 1997.
Anna Maria’s center stands about 10 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 Holocene sediments (sand), from the Holocene, less than 12,000 years old.
The section below crosses 3 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 5 mi of the line.
Limestone, dolostone. Age: Late Oligocene to Middle Miocene, 12 to 28 million years old. About 2 mi of the line.
Sand. Age: Holocene, less than 12,000 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.

Anna Maria has a humid subtropical climate. Summer afternoons average 92° in August; winter nights fall to about 52° in January. About 49 inches of rain fall in a normal year.
On November 14 Anna Maria normally reaches 80° and falls to 60°. The record high is 89°, in 2018; the record low 36°, in 1968. The most rain on this date, 4.80 in, fell in 1997.
Normals 1991–2020 and records since 1911 from the Sarasota-Bradenton Area threaded record (Sarasota Bradenton Airport, 14 miles southeast). NOAA, through RCC-ACIS.
