Conditions at Playa Ostional in September
September: Maximum Size, Challenging Texture
September serves up huge amounts of swell, but it demands patience. The average height is still 1.5m (5ft) with a 13.1s period, and the directional consistency is remarkable: SSW (66.7%) and SW (28.8%) combine for over 95% optimal swell. The issue is wind. Ideal wind falls to 37%, the lowest of the year, as the onshore SSW/SW/WSW/W group swells to 31.1% of the total wind distribution. Combined with heavy tropical rain (8.75mm/day), September often looks inviting from the sand but contests the surface with lumpy texture and swept-out lines. Water temp eases slightly to 28.9°C while air temp averages 26.7°C. Still, between tropical waves and the occasional east-Pacific cyclone, September can produce serious juice for experienced surfers who don't mind the mess.
