Conditions at Playa Grande in March
March: Swell Taper Begins, Trades Refuse to Quit
March sees the first noticeable drop in average size, down to 1.6m (5ft), with the period easing to 7.9s. The swell distribution is still top-heavy: 85.9% from the NE, with 29.2% in the 1-1.5m range and 30.5% in the 1.5-2m range. So there are still plenty of 4-6ft (1.2-1.8m) waves, but they remain short-period windswell. The wind rose looks almost identical to the heart of winter - NE and NNE together account for 85.6% of observations - and the ideal offshore wind score is a token 1%. A few more light-wind hours sneak in than in February, but the overall picture is still onshore and lumpy. Rainfall is still low at 0.81mm/day and the water is 27.6C; only the most determined surfers will be out at dawn looking for a temporary clean window.
