March: The South Swell Engine Wakes Up
March is a transition month with a serious kick in size and period. The average wave height reaches 4-5ft (1.4m) and period climbs into the powerful 13.3s class, signalling that long-period S/SW groundswell is arriving more regularly. SSW dominates with 47 percent of the directional spectrum, SW follows with 19 percent and S adds 14 percent - together, close to 80 percent is coming from the preferred south-southwest quadrant. The proportion of 1.5-2m (5-6.5ft) waves almost doubles from February, so the better sessions start to have real punch.
Wind quality takes a small step back: ideal conditions fall to 47 percent. West and southwest winds pick up, with WSW and SW each near 12 percent and more frequent 10-20kph afternoon sea breezes. Still, the mornings offer calm NW/NNW offshore flow. With air at 28.2°C, water temperature warming to 27.9°C and little rain at 0.10mm/day, March is a promising shoulder month - a bit more care with wind timing is required, but the swell is steadily building.
