Seymour, Texas

The climate is humid subtropical (Köppen: Cfa) with an extreme temperature deviation, but much of the time, the variation is always more and the warm weather prevails over the cold as the averages and the records show. Its subtropical location and south of the center of a large land mass bring occasional outbreaks even to a latitude and not very high altitude. The climate in this area is characterized by hot, humid summers and generally mild to cool winters, sometimes cold.[8] On August 12, 1936, Seymour witnessed the record highest temperature in Texas (120 °F) (49 °C), a record that was tied by the city of Monahans on June 28, 1994.[9]

Seymour is within the area underlain by Texas Red Beds, which are strata of red-colored sedimentary rock from the Early Permian. The fossils of Permian-period vertebrates in the Texas Red Beds were first discovered by Edward Drinker Cope in 1877.[10][11] Subsequent research has revealed rare fossils of Permian amphibians such as Trimerorhachis,[12] as well as rich deposits of other Permian tetrapods such as Dimetrodon and Diadectes.[13] The order Seymouriamorpha and genus Seymouria, which were first discovered in the Seymour area, are named after the city.[14]
