90° on Nov. 16, 2025, the hottest reading for this week of the year since 1930. Next is 87° in 2005.
Deer Park’s center stands about 30 ft above sea level. Within three miles the land runs from 0 ft to 50 ft, a difference of 50 ft: nearly flat ground.
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.
Clay, silt. Age: Pleistocene, less than 2.6 million years old. About 16 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Sand, fine-detrital. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 0.9 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 Deer Park reaches Galveston Bay and the Gulf of America by way of Armand Bayou and Clear Creek: about 17 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Deer Park; river miles along the main stem, rounded.
Deer Park has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 46° in January. About 56 inches of rain fall in a normal year.
On November 14 Deer Park normally reaches 73° and falls to 54°. The record high is 86°, in 2025; the record low 31°, in 1940. The most rain on this date, 2.76 in, fell in 1998.
Normals 1991–2020 and records since 1930 at Houston William P Hobby Airport, 10 miles west-southwest. NOAA, through RCC-ACIS.
