Some surfers still believe that you can't surf in the south of Fuerteventura. However, there is no rational reason for this claim. Many surf spots on Fuerteventura are located in the south.
Fuerteventura has a wave window of more than 180 degrees. This means that you can find surf spots on almost all coasts and beaches of the island where waves break regularly.
At most of the surf spots in Fuerteventura, the waves come from a northerly to westerly direction. These waves are created by low pressure areas far away in the North Atlantic. The energy of the wind from these low pressure areas is absorbed by the water surface, travels thousands of kilometres across the Atlantic and arranges itself into clean swells. When this swell, also called " groundswell" in surfing language, hits the coast of Fuerteventura, beautiful waves break at the surf spots.
Obviously, on an island that is only about 100 kilometres long, these waves do not break differently in the north and south.
