May: The Summer Shadow Begins
May is when the summer pattern tightens its grip. The average period remains long at 13.8s, but the swell direction becomes even more locked in to the south. S and SSE swell together account for 86.6% of all observations, with the preferred NE, ENE, E and ESE directions almost completely absent. For an east-northeast-facing spot, that means most of this long-period energy passes by or arrives as heavily wrapped, diminished lines.
The wind picture gets worse too. Ideal wind conditions drop to just 29%, one of the lowest marks of the year, while E winds at 15.9%, ENE at 13.5%, and ESE at 11.2% become the dominant flow. These strengthen the afternoon bumps and make the surface lumpy. Air temperatures rise to 25.8°C and water reaches 24.6°C. It is not a total flat-out period, but the surf is grovelly, mostly small, and hard to read.
