Conditions at Playa de San Juan in March
March: Spring Swell with a Northeast Bite
March still holds onto winter's surf quality, with an average swell height of 1.6m (5ft) and a period of 11.8s. The swell distribution favours NNW (35.5%) and NNE (20.3%), while N contributes 15.2% and NW another 13%. Many of these arrivals fall in the 1-2m (3-6ft) zone, so the potential for solid, rippable waves is definitely there when the wind cooperates.
Wind cooperation is still the issue. Ideal offshore flow is limited to 7%, and the strong NNE wind machine clocks in at 32.7%, with NE at 16.4% and NNW at 13.2%. Early spring warmth begins to appear in the air (17.8°C) but the ocean stays at a cool 18.1°C. Look for windows when a passing Mediterranean low flips the wind to the SW, usually overnight.
