Gulf of Tehuantepec (Spanish:Golfo de Tehuantepec) is a large body of water on the Pacific coast of the Isthmus of Tehuantepec, southwestern Mexico, at 16°N 95°W / 16°N 95°W / 16; -95. Many (but not all) Pacific hurricanes form in or near this body of water. A strong, gale force wind called the Tehuano periodically blows out over the waters of the Gulf of Tehuantepec, inducing strong upwelling of nutrient-rich waters which support abundant sea life.
