Los Cabos is surrounded by the Pacific Ocean and the Sea of Cortez (Gulf of California), with the Sierra de La Laguna range cutting through the center of the Cape Region at the end of the peninsula. This produces microclimates on either side of the peninsula, where temperatures in the Sea of Cortez and Pacific Ocean can vary by as much as 15º F. In the summer months, the Sea of Cortez climate is more humid and hotter than the Pacific side; in the winter months, the Pacific side is considerably cooler than the Sea of Cortez. San Jose del Cabo and the East Cape have warmer summers, while Cabo San Lucas has colder and windier winter weather.
