October: Groundswell Season Reborn
October is arguably the best blend of power and wind that Cloud 9 sees all year. Average size jumps back to 3-4ft (1.1m) and the period climbs to 10.2s, giving it the first true long-period signature of the season. NE delivers 49% of swell observations, with a significant NNE component at 20% and N/ENE/NNW filling in the premium directions. Many of those waves are in the 2-5ft (0.5-1.5m) range, but the longer period means they stand up fast on the reef and offer real barrel potential. Onshore NE winds are less persistent than mid-winter, and ideal offshore flow reaches 35%, so there are far more rideable, well-groomed days. Tropical cyclones and shear-line troughs moving through the Philippine Sea are common engines for this swell. With air at 27.9°C, water at 29.3°C, and rain averaging 8.3mm/day, October brings hollow surf without the full monsoon wind penalty.
