April: Transitional Swells and Wind Shifts

As the ocean slowly relaxes, April gives you average swell heights of 6.9ft (2.1m) and a period of 11.2s - still rideable and punchy, but a notch down from deep winter. The swell direction is almost entirely from the NW (25.1%), NNW (19.8%), and WNW (19.7%), creating a strong north-northwest bias for the exposed sandbar. Wave heights are mostly between 1-2.5m, with only a slim chance of overhead-plus bombs. The wind regime begins to transition: the northern thermal (NNW 29.4%) grows stronger, while the offshore NE/ENE/E/ESE quadrant shrinks, leaving ideal wind at only 31%. This means instead of clean, glassy barrels, you'll often see slight bump and texturing on the faces. Still, when a low-pressure system lingers offshore and pulls in easterly flow, April can rise to the occasion with fast, rippable waves. Water temperature creeps up to 15.3°C.
