September: A Hint of Swell in the Tropics
September is the turning point, with the average swell creeping back up to 4ft (1.1m) and the period jumping to 9.1 seconds - a clear sign that the surf engine is beginning to reawaken. The swell direction starts to become more balanced, with NE steering 34.2% and ENE at 33.6%, while NNE contributes 12.7%. The SSW-W window is still mostly empty, but the increase in period adds some much-needed power to the lineup. Wind remains favourable 78% of the time, with ENE (25.0%) and E (20.8%) leading, so surfaces are generally clean. Water is at its warmest of the year, 29.3°C, and September is often the wettest month too (4.91 mm/day). It's a month of potential: the right combination of a northward-tracking hurricane and a light offshore drift can light up the reef with fun, rippable surf.
