94° on Nov. 11, 2023, the hottest reading for this week of the year since 1892. Next is 91° in 2018.
Thonotosassa’s center stands about 50 ft above sea level. Within three miles the land runs from 30 ft to 120 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Undifferentiated sediments (sand, clay), from the Pleistocene to Holocene, less than 2.6 million 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, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 11 mi of the line.
Sand, clay, phosphorite. Age: Middle Miocene to Pliocene, 2.6 to 16 million years old. About 7 mi of the line.
Limestone. Age: Late Oligocene to Middle Miocene, 12 to 28 million years old. About 6 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 Thonotosassa reaches Tampa Bay and the Gulf of America by way of the Hillsborough: about 30 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Thonotosassa; river miles along the main stem, rounded.
Thonotosassa has a humid subtropical climate. Summer afternoons average 94° in July; winter nights fall to about 50° in January. About 56 inches of rain fall in a normal year.
On November 14 Thonotosassa normally reaches 81° and falls to 58°. The record high is 88°, in 2018; the record low 31°, in 1932. The most rain on this date, 2.90 in, fell in 1941.
Normals 1991–2020 and records since 1892 at Plant City, 10 miles east-southeast. NOAA, through RCC-ACIS.
