May: Southern Hemi Swell Hits Full Stride
May is one of the biggest and longest-period months of the year at Barra de Potosi. Average swell size reaches 4.6ft (1.4m), and the period peaks at 14.2 seconds, giving the ocean a deep, powerful feel. The energy is extremely SSW-dominant at 85%, with secondary SW energy at 11% and a little S contribution at 3%. Surf height distribution reflects a more mature swell window: 33% of waves are in the 5-6.5ft (1.5-2m) range, and nearly 3% reach 6.5-8ft (2-2.5m). The problem remains wind reliability, with ideal surf conditions only 13% of the time. WNW and W winds dominate the middle of the day, so the best chances are at first light.
