Conditions at Ciruelo in September
September: Maximum Swell Potential, Minimum Clean Windows
September is the peak of the rainy season and the low point of Ciruelo's consistency curve. There is no shortage of wave height or period - 1.1m (3.6ft) average with a 13.5s period - and the swell direction is almost perfectly from the SSW at 97.3%. The ocean is sending powerful, long-period waves toward this stretch of Panama all month; it is the wind that ruins the party.
Ideal surfing winds fall to 53%, while onshore SW and WSW directions combine for just over 33% and stronger 20-30kph SW events are more frequent. Heavy rain at 11.60mm/day, warm air at 26.7°C and water at 28.7°C round out a humid, wind-affected picture. Occasional tropical or late-season southern pulses can still produce a memorable day, but you will need luck and an early alarm.
