Except for the humid subtropical climate of the eastern part of the state, evaporation exceeds precipitation, resulting in a semiarid or steppe climate that becomes arid in the extreme west of Texas. On average, this region receives between 20 inches (west) and 35 inches (east) of rainfall per year. Central Texas is unique in its landscape structure, with its many hills, rivers and lakes, which make it vulnerable to flash floods. Their comparable “climate country” is Israel or Lebanon.
In general, the climate in Texas ranges from humid and muggy in the east to arid in the west. The sun shines all year round in the Lone Star State, which is beautiful until the sweltering heat of June, July, and August (and, let's face it, most of September). And speaking of the heat, it's important to note that Texas's climate is changing; according to the Environmental Protection Agency, the state has warmed between half and one degree Fahrenheit in the last century.
