May: Peak Size, Peak Frustration
May delivers the largest average swell height of the calendar year at 4.5ft (1.4m), with a year-max 14.2s period. The Southern Hemisphere winter machine is in full swing: SSW makes up 87.5% of the swell, and a solid 22% rides in the 5-7ft (1.5-2m) range, with a few 7-8ft (2-2.5m) sets on better days. Yet the wind is the wildcard - ideal offshore conditions occur only 46% of the time, the lowest of the year. The trade wind flow weakens, N/NNE becomes scarce, and S/SSW/SW onshore tendencies increase with 5.26mm/day of rain. When a dawn gap-wind lines up with this long-period SSW, Punta Roca can be flawless; otherwise, afternoon onshores will test your patience.
