The average annual precipitation in Texas is around 34 inches. Due to the large number of climate zones present in Texas, rainfall varies dramatically from one end of the state to another.
As the second largest state in the U.S., Texas occupies a large area with many geographic regions. Each one has its own climate characteristics affecting annual precipitation. Rainfall differs from the eastern border to the western one by as much as 50 inches. For example, Mauriceville, located in the southeast section of Texas, receives as much as 64 inches in a year, while El Pas in the west only collects around 6 inches.
