Conditions at Barra de la Cruz in September
September: Big Swell and Tropical Chaos
September is the statistical peak of the swell calendar, with average heights reaching 5.6ft (1.7m) and period still strong at 13.2s. The wave rose is heavily weighted toward SSW at 53.7%, S at 24.0%, and SW at 10.7%, with the 5-6.5ft (1.5-2m) class especially well represented. There is also a small 6.5-8ft (2-2.5m) contribution from SW. This is the heart of the Eastern Pacific tropical cyclone season, so there is real potential for energy beyond the average. The downside is wind: ideal offshore flow is only 43%, while WSW and W winds combine for around 26% and E/ENE flow adds another 22%. Rain is heavy at 6.31mm/day, water temp is warm at 29.9°C. Chase the windows between squalls and tropical waves, and you can find powerful, mechanical south swell.
