Conditions at Playa Blanca in March
March: Longer Periods and a Slight Rise in Size as Autumn Begins
March marks the first subtle shift toward autumn. Average swell height nudges up to 5-6ft (1.7m) and the average period jumps to 13.6s, the longest of the year. SW swell becomes even more dominant at 60%, with WSW adding 36%, and more energy arrives in the 6.5-8ft (2-2.5m) class, with a trace pushing over 8ft (2.5m).
Wind quality remains poor, with only 1% ideal conditions. SSW winds dominate at 31%, followed by SW at 27%, while WSW and W add another 29%. This means the same low-pressure systems generating the swell are also putting Playa Blanca under onshore wind. There is serious power in the water, but without one of those rare offshore NE/ENE/E/ESE interludes, the spot is mostly heavy, bumpy and hard to surf cleanly. Air temps cool slightly to 19.2°C, water temp is 14.4°C, and rain is still scarce.
