Smoky Skies Over the Isthmus of Tehuantepec, Mexico – May 22nd, 201017.0N 95W
Smoke from numerous fires veils the skies over and near the Isthmus of Tehuantepec, in southern Mexico. The isthmus is situated between the Gulf of Campeche on the Gulf of Mexico to the north, and the Gulf of Tehuantepec on the Pacific Ocean to the south.
From gulf to gulf the isthmus is 137 miles (220 km) wide at its narrowest part; and it is 120 miles (193 km) from the Gulf of Campeche to the head of Superior Lagoon, an inlet on the Gulf of Tehuantepec. The isthmus is a broad, plateaulike ridge. Its climate is hot, but Pacific winds often bring relief. The northern side is swampy.
