September: Tropical Energy and Powerful Swells
September brings the most dynamic mix of the year. Average height holds at 4.3ft (1.3m), period 13.2 seconds. Swell direction is still dominated by SSW (68.5%), but the SW component jumps to 23.0%, with WSW at 1.8%. This more westerly angle can create a slightly more walled-up, open face at Puerto Sandino. There is more 5-6.5ft (1.5-2m) energy - around 18% - plus a few 6.5-8ft (2-2.5m) pulses. East Pacific tropical storms and hurricanes can add extra SSW and WSW swell during September. Ideal wind drops to 60% as the trades relax; keep an eye on afternoon S/SSW seabreezes and showers. Water temp is 29.5°C, rain is at its annual peak with 9.56mm/day, and air temps average 27.8°C.
