Conditions at Santana in March
March: The Swell Window Begins to Open
March is a true transition month. The average wave period jumps from 8.9s to 11.0s, a clear sign that longer-period southern energy is finally reaching Central America. The useful S/SSW/SW/WSW quadrant climbs to roughly 25% of the total swell, with SSW alone delivering 9.3% and SW another 8.9%. Wave heights concentrate in the 3-5ft (1-1.5m) range, with plenty of 1.5-3ft (0.5-1m) grovelers in between. The average swell height remains a consistent 4.6ft (1.4m), but the character of the surf is changing for the better.
Winds are still dominated by ENE (66%) and E (21%), but speeds are more variable and ideal surf wind rises to 9%. This is still a marginal month compared to late spring, but the first true SSW pulses can produce long-period waves-especially in the morning before the trades fill in. Air temps average 28.3°C, water temp is 26.5°C, and rain is limited at 0.12mm/day. The season is building.
