September: A Glimmer of Change

September is still very much on the wrong side of the wind, but the trade winds finally start to ease. Average swell holds at a strong 2.0m (6.5ft) and the period remains 14.3s, with SSW pumping in 71% of the total energy and S adding 11%. The 1.5-2m (5-6ft) class is 42%, while 2-2.5m (6-8ft) adds another 34%. ESE and SE winds each sit around 37%, but wind speeds are lighter than midwinter, and the SSE component (13%) points to the trades relaxing slightly. Ideal wind is still only 2%, so clean conditions are rare and transient. Rain is minimal (1.1mm/day), air temps around 24.4°C, and water temp holds at 26.7°C. Patience can pay off during the calmest hours, but this month still leans heavily toward low quality.
