Ollie's Point • Statistics for September

September: Maximum South-Southwest Focus

September sees the swell direction spectrum lock almost completely into the favorable southwest quadrant. SW swell jumps to 42.3 percent, SSW matches with 33.2 percent, and S adds 6.3 percent - that is over 80 percent of the total energy coming from the directions Ollie's Point was built for. The average swell height is 3.9ft (1.2m) and average period is 12.9s, with the largest share in the 3-5ft (0.9-1.5m) range: 32.8 percent of all swell arrives from SW in that class, and 24.5 percent from SSW. The trade winds are at their least dominant of the year, with NE only 18.2 percent and ENE 13.3 percent, though more variable S/SW winds appear - a reminder that the wet season is at its peak. Rain is heavy at 8.68 mm/day and air temperatures average 26.2°C. Ideal wind conditions clock in at 53 percent, so there are exceptional windows between tropical waves. When it comes together, this is some of the best-aligned, longest-period surf of the year.
