October: Solid Swell and a Changing Wind Regime

October remains very much a surfable month, but with a transitional feel. Average swell height is 1.5m (4.9ft) and the average period is 13.5s - still long and powerful. SSW provides 55.1% of the swell and S adds 34.1%, meaning the break is seeing a near-continuous stream of 3-5ft (1-1.5m) waves (54.5%) and a solid 39.6% in the 5-6.5ft (1.5-2m) category. The mix can produce lined-up, hollow walls when conditions align.

Wind is where October starts to get interesting. The SE trades still dominate at 25.4% SE, with SSE at 14.3% and ESE at 11%, and the ideal surfing wind share is a respectable 46%. But the wet season is approaching fast: rainfall jumps to 8.98mm/day, and W/NW flow is slowly building again. Morning sessions are often excellent, with offshore E/NE components and clean groundswell. By the afternoon, convection and sea breezes can add lump. Water temp stays at 28.5°C and air temps hold at 27.1°C. It is a great month for surfers who like the best of both worlds - substantial swell and quieter crowds.
