Conditions at Playa Malibu in September
September: Peak Rain, Fickle Winds
September is the climatological peak of Panama's rainy season, and that shows in both the wind and the swell data. SSW swell is almost the only game in town-96.2% of all wave energy-but the average period drops to 10.7s and the average height stays at 0.7m (2.3ft). There's no shortage of waves from the right direction; the challenge is keeping them clean.
Ideal wind falls to 51% as the ITCZ parks overhead. NNW flow weakens to 19.4%, while SSW, SW, WSW, and W winds combine for roughly 38%, bringing frequent onshore and cross-shore conditions. Air temps sit at 26.2°C, water temp at 29.4°C, and precipitation is the highest of the year at 9.21 mm/day. The best surfing happens in the breaks between tropical rain bands, when a brief pulse of offshore NW wind cleans up the 2-3ft (0.6-0.9m) SSW swell. It's a challenging but rewarding month for the patient.
