Conditions at Isla de Santa Marina in April
April: Spring Swell, Cleaner Conditions
April is the true shoulder month. Average swell height eases to 1.5m (5ft) and period compresses to 10.8 seconds - enough window to hold the beach's shape, but with less raw power than winter. The northwest remains the engine: NW 43 percent, NNW 21 percent, WNW 17 percent. The combination means waves are more frequent than large, with plenty of 3-5ft (0.9-1.5m) peaks. When a late-season Atlantic low lines up, though, 6ft-plus (1.8m) waves are still on the cards.
Wind-wise, ideal surfing conditions sit at 43 percent. The breeze starts to spread into ENE and more easterly directions, giving an increasing number of clean, glassy mornings. W and WNW winds are still around, especially in unsettled spells. Sea temperature rises to 13.7°C, air averages 12.1°C, and rain eases slightly. April is about picking the right day and enjoying the first taste of spring warmth.
