May: Summer Windswell Takes Over
By May, the winter swell engine is winding down. The average height falls to 1.6ft (0.5m) and the average period is 6.7s. The swell roses are dominated by SSE (17.5%), SE (16.8%), ESE (15.6%) and S (14.6%), almost all of it in the small category - the vast majority of observations are under 1.6ft (0.5m). The wind field is more onshore, with SSW (9.6%), S (9.3%) and SW (8.3%) forming a persistent onshore flow. Only 5% of the time does the wind blow ideal offshore. Morning glass-offs and late-period remnants of distant coastal storms can still produce groveling fun waves, but you will have to work for them. Water temperature jumps to 15.8°C, air temps to 15.7°C, and the crowds start to appear.
