Anxiety is building at Half Moon Bay. A medium-sized NW swell is hitting the shores of California and the 2012 Mavericks Invitational may be called on, in the next days, if all weather conditions meet properly - wave face, tide, wind and wave period. Watch the Wave Height Forecast for the West Coast of USA, here.

The best 24 big wave surfers in the world are ready to answer the call and fly to the San Francisco coast, in 24 hours. Wave conditions are expected to kick the adrenaline, in what is considered to be the best big wave challenge in the world.

The best day may, however, not come. Since 1999, the Mavericks surf contest was only contested seven times. Jeff Clark wants a classic and perfect Mavericks day, in order to blow everyone's mind. Swells are being tracked every day, every hour.
