87° on Nov. 17, 2025, the hottest reading for this week of the year since 1897. Next is 86° in 2020.
Seadrift’s center stands about 15 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 Beaumont Formation, areas predominantly clay (clay, silt), 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. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 6 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 4 mi of the line.
Clay, silt. Age: Pleistocene, less than 2.6 million years old. About 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.
Rain that falls on Seadrift runs straight into the Gulf of America.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Seadrift; river miles along the main stem, rounded.
Seadrift has a humid subtropical climate. Summer afternoons average 93° in August; winter nights fall to about 45° in January. About 42 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1897 at Austwell, 8 miles west-southwest. NOAA, through RCC-ACIS.
