September: Signs of Life in the Swell Window

September is the first month to show real light at the end of the summer tunnel. The average wave height is still modest at 3ft (0.9m), but the average period jumps to 10.1 seconds, a clear sign that longer-period energy is starting to arrive. The swell rose broadens back toward the north: NNE contributes 11 percent, NE 30 percent and ENE 31 percent, with another 16 percent from E, so more of the wave energy is finally feeding the NNE-facing beach. Combined with ideal offshore wind 67 percent of the time--again dominated by S, SSW and SW breezes--September can produce unexpectedly clean, head-high-plus days when a 5ft (1.5m) swell pulse lines up. Air temps average 26.8°C (min 23.1°C, max 36.3°C), water temperature is 29.5°C, and rainfall is low at 6.41mm/day. This is the beginning of the run-up to prime season; the surf is small but increasingly organized.
