Conditions at Pico Alto in March
March: The Autumn Transition Begins
March is where Pico Alto starts to wake up. The average swell height climbs to 5.2ft (1.6m), and the average period lengthens to 13.5s, a signal that more distant, powerful South Pacific storms are starting to send their energy north. SSW swell dominates at 83 percent, with SW supplying most of the remaining 16 percent. The distribution shifts noticeably toward bigger surf: 44 percent of observations fall in the 5-6.5ft (1.5-2m) range and nearly 8 percent reach 6.5-8ft (2-2.5m).
Winds remain mostly southerly and south-southwesterly, with ideal offshore directions only 2 percent of the time. Air temperatures are still warm at 21.2°C, while the water drops slightly to 19.2°C as upwelling begins to strengthen. The incoming autumn swell is great news, but a clean Pico Alto still depends on those early offshore moments before the S/SSW wind takes over.
