August: Hurricane Season Adds Extra Punch
August brings the tropical cyclone factor into play. The average swell remains solid at 1.4m (4.6ft), with 13.2s periods, and SSW (67.0%) plus S (27.3%) swells deliver a steady diet of clean groundswell between hurricane events. The S component is still strong, which is excellent for Petacalco's exposure. More than a quarter of the waves are 1.5-2m (4.9-6.6ft), and the occasional 2-2.5m (6.6-8.2ft) set appears. However, rain reaches 6.48mm/day and water temperature peaks at 30.3°C; wind is ideal only 45% of the time. When a tropical cyclone passes south or west of the region, episodic SSW/S pulses can push well beyond the monthly averages, though often accompanied by stormy winds.
