Texas experiences higher rainfall due to the warm, humid air from the nearby Gulf of Mexico.

Texas receives more rainfall than many other states because of its proximity to the Gulf of Mexico, which supplies warm, humid air. This moisture-laden air moves inland, especially impacting eastern Texas, where it contributes to frequent rainfall and humid conditions. The Gulf’s influence on Texas’s climate is particularly strong in spring and summer, leading to thunderstorms and even severe weather. In contrast, states farther from the Gulf, like Arizona, Colorado, and Montana, are less affected by this moisture source and generally experience drier conditions. Texas’s location makes it uniquely susceptible to the Gulf's warm, wet air, resulting in higher rainfall.
