September: Late-Season Swell and Trade Pressure
September is the transitional tail of the winter season. Average height remains solid at 7.2ft (2.2m), period shortens to 11.9s, and ideal offshore wind is still only 24%. Swell direction is favorable, with SSE and S leading the way and SSW contributing 8.2%; however, the SE/ESE component is more prominent, hinting at the changing season. The wind field is dominated by strong ESE and E trade flow-together over 52% of observations-so bumpy afternoons are common. Still, the ocean temperature of 26.2°C, air temperature of 25.0°C and just 1.54 mm/day of rain make it a great month for heavy, drifty sessions if the wind cooperates.
