Conditions at Yerbabuena in March
March: Transitional Winter Power
March holds many of January's traits, but the Atlantic mood is starting to change. The average wave remains healthy at 4.6ft (1.4m) with a 10.6s period. WNW still leads at 40.6%, while W increases to 19.7%, giving the coast a slightly more westerly flavor than midwinter. E windswell is significant at 12.6%, and secondary front energy from WSW begins to show up. For Yerbabuena, the mix of W and WNW groundswell can wrap around the headlands and produce consistent surf, but the standout days are still tied to fleeting S/SW swells.
Offshore wind reliability drops to 32% as high-pressure systems become more common over the Iberian Peninsula. NNW at 8.4% and NW at 7.3% remain the most useful offshore sources, but strong E/ESE winds now account for 36% of all wind observations, adding afternoon chop to many days. Air temperatures warm to 15.3°C, water sits at 15.8°C, and rainfall eases to 2.06mm/day. Bring a shortboard and a spring suit; waves are still good, just a little less predictable.
