Conditions at Costa Azul in May
May: Still Waiting for the Tide to Turn
May continues the spring pattern with high-quality winds and a strong southern bias. The average swell height is 1.1m (3.6ft) and the period remains a robust 14.1s. Almost all energy comes from S (27.4%) and SSW (71.9%), leaving no swell from the optimal ENE-ESE direction. The wind picture is superb - ideal offshore wind 89% of the time, with WNW and WSW flows prevailing. Yet the lack of east-angle means Costa Azul remains largely in the shadow. The surf, when it arrives, is soft and section-heavy, more suited to longboarders or the occasional closeout hunter. Sea surface temperature already reaches 24.0°C and air temps average 23.2°C, hinting at the approaching summer warmth. For now, only a strong, well-angled tropical storm or a rare counter-seasonal front can produce the east-angled waves this break desperately needs. Keep an eye on the outer swell buoys for that sudden shift.
