March: First Hints of Southern Swell
March is a transition month. The trades are still the dominant storyline -- ENE winds blow 78.9 percent of the time, mostly 20-40kph -- but there is a noticeable increase in the variety of swell directions. Average period climbs to 11 seconds, suggesting more organized groundswell than the short-period windswell of January and February. The energy distribution is more balanced: ENE remains the largest at 32.3 percent, but SSE 6.8, S 4.8, SSW 9.3, SW 8.9 and WSW 1.8 begin to show up. That adds up to around 21 percent of the month with waves from the favorable southwest quadrant, most of it in the 1-1.5m (3-5ft) range. Ideal offshore wind remains limited to 6 percent, so the majority of those southern pulses will be chopped up by strong easterly flow. Still, as high pressure weakens and the first South Pacific low-pressure systems push energy north, the early season starts to feel alive.
