Laredo, TX

Laredo has a hot semi-arid type of climate (Köppen climate classification BSh) with long, hot summers and short, mild winters. Laredo lies on the north bank of the Rio Grande River on the Rio Grande Plains, east of the Mexican Mountains in Webb County of the American state of Texas. The Sierra Madre Oriental Mountains, Gulf of Mexico, and Chihuahua desert chiefly influence Laredo's harsh climate.
