As one can see in the Magicweed guide Playa Madera is incredibly consistent, ranking over 80% swell consistency for over 7 months a year, and over 50% 9 months a year.

This make it a great place to build a B&B, hotel, or a house that can be traded for another in North America or Europe Homeexchange for a few weeks a year..
