It is bordered to the north by the United States, to the south and west by the Pacific Ocean, to the southeast by Guatemala, Belize, and the Caribbean Sea, and to the east by the Gulf of Mexico. Covering approximately 1.96 million square kilometers, Mexico is the third-largest country in Latin America and features a diverse geography that includes mountains, deserts, rainforests, and coastal plains.

The Sierra Madre mountain ranges stretch across the country, creating dramatic variations in climate. The Sierra Madre Occidental runs along the Pacific coast, while the Sierra Madre Oriental spans the Gulf coast. The country also boasts high plateaus, including the Central Mexican Plateau, and significant coastal plains on both the Gulf of Mexico and the Pacific Ocean. The Yucatán Peninsula in the southeast is home to vast tropical forests and pristine beaches. Mexico’s diverse geography influences its climate, which varies from tropical to desert to temperate, depending on the region’s altitude and proximity to the coasts.
