Conditions at La Selva in March
March: Spring Power Surge
March is a sneaky good month at La Selva. The average wave period ties the yearly high at 9.1s, and the average swell height remains a solid 5ft (1.5m). The optimal directional window is well represented: NNE at 18%, NE at 26% and the N/NNW components combine to push the total favourable share above 52%. ENE still provides a strong background of trade swell at 35%, but the more north-tilted energy is what allows La Selva's sandbars and reef sections to really stand up.
Ideal offshore wind days climb to 33% this month, the best since the previous autumn, as the trade-wind regime becomes lighter and more variable. This is the start of the spring window where you can score clean, medium-period waves without the heavy onshore blow of deep winter. Air temperatures hover near 25.3°C while the ocean sits at 26.3°C, making March an increasingly comfortable time to surf.
