March: Last Great Monsoon Push
March marks the transition out of the wet season, but it still delivers an excellent 45% of ideal wind for the south-facing beach. The average swell height dips slightly to 1.3m (4ft), yet the period lengthens to 13.4s, adding real power. Swell direction shifts more toward SSW (64%) and SW (33%), with the 1-1.5m size range dominating; waves in the 1.5-2m range still show a solid 23%. During the good windows, W-WNW winds groom the incoming groundswell into clean runners. As the southeastern trades start to creep in from ESE/SE, the window narrows, but early mornings remain worth the dawn patrol.
