Either the Baja California or the Yucatan peninsulas. Both have subtropical climates. Baja California has a subtropical desert climate while Yucatan has a subtropical savanna (hot and humid) climate.
Both are peninsulas located in Mexico. "Baja" is the common name for the Baja California Peninsula, which protrudes from southern California and runs along north-western Mexico. Some important cities in such peninsula are Tijuana, Ensenada, Mexicali, La Paz and Los Cabos. Yucatan is the common name for the Yucatan Peninsula, which is located in south-eastern Mexico and touches the Gulf of Mexico as well as the Caribbean Sea. The most important cities in there would be Cancun, Merida, Tulum or Cozumel.
No. Mexico is located within the mainland of the North American continent, and it has two major peninsulas: the Yucatan Peninsula touching the Gulf of Mexico and Caribbean Sea, and the Baja California Peninsula, touching both the Pacific Ocean and the Sea of Cortes.
If you mean the Baja California Peninsula, it is in Mexico. There are other peninsulas in both Mexico and the United States, but "Baja" is the one that causes so much confusion.

There are two, "Baja California Norte" and "Baja California Sur" and both of them belong to Mexico.
