September: The Season Turns the Corner
September is where the fair season begins. The average period jumps to 9.0s - the highest of the year - while wave height rises to 0.8m and ideal wind sits at 13%. The wave rose is loaded with favorable east energy: E (37.5%) and ENE (35.6%) dominate, with NE (13.3%) also back in the mix. There is more size in the system too, especially from ENE, where 4.7% of waves are 1-1.5m and 1.6% reach 1.5-2m. The catch is wind: ENE (15.0%), E (13.3%) and ESE (12.2%) are all onshore, leaving only brief windows after frontal passages or tropical storm interactions. Water temperature remains warm at 28.6°C, and rain is plentiful at 6.18mm/day. September's promise lies in the tropics. A properly positioned hurricane well offshore can send powerful 10-14s swell marching into the ENE-facing beach, and if the winds swing SW in its wake, you will be rewarded with the first truly good waves since spring.
