Conditions at Palmarcito in May
May: Southern Ocean Swell Hits Full Stride
May is where the southern hemisphere swell peak kicks in. Average height jumps to 1.4m (4.6ft) and the average period hits 14.2s, the longest of the entire year. SSW is the clear star at 87.5%, with S 7.9% and SW 4.1%. There is a big step up in 1.5-2m (5-6.5ft) waves, especially from SSW at 20.3%, plus occasional 2-2.5m (6.5-8ft) sets. The catch is wind: the ITCZ begins to push north, ideal surf conditions drop to 53%, and E/SE/S winds become more common. Rain increases sharply to 5.26mm/day while the water temperature climbs to 30.2°C. Expect bigger, more powerful waves, but the best chances for clean conditions will be in the early morning.
