Conditions at El Huayaco in May
May: Winter Swell Builds as the South Pacific High Tightens
The approaching austral winter brings an average swell height of 6ft (1.8m) and a powerful 13.6s period. SSW again dominates at 84.4 percent, while S and SW contribute another 10.1 percent, putting confidence in the exposed southwest-facing banks. Over three-quarters of the swell measures 5ft (1.5m) or more, so there is real size in May.
Wind quality, however, continues to deteriorate. The South Pacific High strengthens and the coastal pressure gradient compresses, driving S and SSW winds at 10-20kph for over 74 percent of the time. Combined S/SSW flow is 91.2 percent, and the onshore total is essentially 99 percent. Ideal offshore flow is 0 percent. Water temperature falls to 17.0°C, air temps average 18.6°C, and the desert coast stays bone-dry. Expect stormy, bumpy surf unless a rare thermal wind break lines up.
