While many believe the weather in southern Spain is always sunny and hot, the region actually has significant climate diversity due to its location between the Atlantic Ocean and Mediterranean Sea and varied terrain. There are at least six different climate types in southern Spain, including Mediterranean, semi-arid, oceanic, mountainous, continental, and subtropical. Climate is determined by measuring average temperature and rainfall over 30 years, not just one month or year. This variety is why southern Spain can be considered a "small continent" with climates ranging from freezing mountain tops to semi-desert and subtropical areas all within its borders.
