May: Bigger, Cleaner and Deadly Consistent
May delivers the best wind-to-wave balance of the entire year. The average swell height jumps to 2.3m (7.5ft) with 12.9s period, and the direction mixes between SW (33.0%), WSW (16.5%) and W (5.0%) - exactly the angles that light up the exposed stretch. With nearly 29% ideal wind conditions, it's the peak month for scoring properly sized waves without the winter wind penalty. The wind rose is much more diffuse than summer with decent shares of NE/ENE/E/ESE offshore flow and fewer prolonged seabreeze spells. Expect powerful, well-groomed lines rolling through the reefs and points all month. Air temps drop to 17.1°C, precipitation rises to 2.84 mm/day as the first strong fronts arrive, and water holds at 20.2°C - autumn has arrived in earnest.
