September: Monsoon Crossroads
September is a transition month where the southwest monsoon starts to mix with the first hints of the northeast monsoon. Average swell height stays at 2ft (0.6m), period 7.0s, and ideal wind 19%. The swell direction becomes much more varied: WSW still leads at 29.7%, but W is 17.8%, WNW 12.1%, NW 10.8%, and NNW is back up to 21.4%. This mix of directions gives Bauang more chances at the optimal WNW-to-NW window, but it also makes the surf less organized. Heights are still small: around 54% below 2ft (0.5m), 36% in the 2-3ft (0.5-1m) range, and 7% in the 3-5ft (1-1.5m) range, with a little more in the bigger bands than earlier in summer. Wind directions are split across SSE, S, SSW, and a growing NNW component, leaving only 19% clean. Rainfall remains heavy at 14.48mm/day, water temperature is 29.7°C, and air averages 23.1°C. September can serve up fun windows, but consistency is still just okay.
