September: Hurricane Season's Best Shot
September is the first month where the surf really regains some pulse. The average swell height climbs to 0.8m (2.6ft) and the average period jumps to 8.6s, the highest of the year, indicating more powerful, longer-period energy. E and ENE are the big players at 34.1% and 32.0%, with ESE at 13.8% and NE at 11.8%. The percentage of 1-1.5m and 1.5-2.5m waves increases noticeably, especially from ENE, and tropical storms or distant hurricanes can deliver heavier, pumping surf. The downside is that ideal wind remains just 13%, with ENE, E and ESE winds blowing onshore much of the time. Still, between late-summer tropical swells and improving fall groundswells, September offers some of the best raw wave potential in months. Water temperature is 28.6°C, air temperature averages 27.4°C, and precipitation is high at 6.25 mm/day.
