Conditions at Medewi in September

September: SSW Swell Perfection, Wind Still Messy

September holds onto the dry-season swell window, with an average height of 1.3m (4ft) and a 14.0s period. The direction swings back toward SSW: 77 percent SSW and 23 percent S. That is about as good as it gets for the Medewi reef. But the wind is the biggest limiting factor, with only 11 percent ideal conditions. SE winds remain dominant at 36 percent, ESE at 31 percent, and SSE at 25 percent, creating persistent cross-shore textures on the faces. The swell is there, often in the 3-6.5ft (1-2m) range, but you will need a lucky weather day, a morning offshore, or a more sheltered corner of the point to find clean shape. Air temperature is 24.4C, water temperature is 27.1C, and rainfall is still low at 1.14mm/day.
