Conditions at Mirleft in March
March: The Last Big Push Before Spring
The ocean has not read the calendar in March. Average swell height remains a solid 6-7ft (2.1m), but the average period eases slightly to 12.3 seconds, still in the powerful 10-14 second class. Swell direction remains excellent, with NNW at 35.2% and NW at 31.3%, while WNW adds 10.0%. Many of the biggest, most organized groundswells of the season can still roll in during the first half of March.
The tell-tale sign of spring, however, is the wind. NNW winds climb to 27.4%, while NW and WNW add another 12.4%, making onshore conditions more frequent. Ideal offshore flow drops to 36%, so surf quality becomes increasingly dependent on the exact timing of frontal passages. When the breeze backs to the S/SSW/SW quadrant, the beach still offers excellent long-period surf. Air temperature warms to 16.8°C and water remains 17.2°C, so spring sunshine can make those clean windows feel extra rewarding.
