September: Monsoon Eases, but Clean Windows Are Still Rare
September marks the beginning of the long transition away from the southwest monsoon, though on the surface it still looks and feels like the low season. The average swell height remains an impressive 5ft (1.6m), the period is a solid 10.5s, and SSE plus S account for roughly 84 percent of the swell energy. Around 63 percent of the surf comes in the 5-6.5ft (1.5-2m) range, with plenty of 3-5ft (1-1.5m) stuff in between. The swell is definitely not the limiting factor.
The wind pattern, however, still tilts against Antiques. WSW and W are the most common directions, and ideal offshore wind is only observed 28 percent of the time. Rain remains heavy, with 6.23mm/day, while air temperature stays at 27.5°C and water sits at 29.3°C. Compared to July and August, there are slightly more windows when the wind briefly veers N or NW, and those windows can offer big, grinding reef waves. But consistent quality remains elusive until the monsoon circulation fully breaks down.
