March: First Taste of Autumn Power
March marks the turning point. Average swell height climbs to 5.5ft (1.7m) and the period jumps to 10.5s, pushing waves into the powerful long-period category. The dominant S swell (21.1%) is now pairing with a healthy SSE component (15.7%) and SE (11.8%) to deliver more organized groundswell to the southeast-facing beach. Crucially, the wind is ideal 50% of the time, with a notable increase in NW and NNW flows. This is when Mangamanu starts to show its true shape, especially on the days when an offshore WNW breeze polishes the faces. Water temps have cooled to 15.7°C (60°F) and rain is picking up slightly with passing fronts. For those seeking a balance of warm weather and meaty surf, March is an excellent choice.
