August: The Dog Days of the North Shore
August continues the summer pattern with barely a flicker of hope. The average swell height holds at 1.6m (5.2ft), the period stays at 8.8s, and the E direction reaches its seasonal peak at 68.2% of the wave rose. ENE adds another 25.1%, meaning 93.3% of the month's swell is coming from the two directions that least favor this north-facing reef. Preferred north quadrant swell is essentially absent, with only a trace of NE (0.3%). Ideal wind days tick up from zero to a still-measly 1%, while ENE/E trades blow 94.8% of the time. On the bright side, the ocean is warm - water temp hits 26.5°C - and the air is at 22.5°C, so it is a beautiful month to be on the island, just not at the lighthouse. Any wave that breaks here will be short-period, trade-driven and crumbly, best left for the longboard or a day off.
