Conditions at Ocean Reef Park in September
September: Tropical Groundswell Wildcard
September is where the season pivots. Average height rebounds to 3-4ft (1.0m) and period jumps to 8.2s, while ideal wind is still low at 18%. More importantly, the swell direction concentrates heavily in the NE (32%) and ENE (30%), classic directions for an east-facing beach. Some of that is solid groundswell from early-season extratropical storms, but much is tropical: 1.5-2.5m waves become possible when hurricanes spin up off the Southeast coast. The wind, however, is still mostly easterly, ENE (14%), E (15%), ESE (13%), NE (8%), and often too strong for truly clean conditions. Water remains warm at 29.5°C, air at 27.6°C, and rain is heavy at 6.50mm/day. The potential for powerful, well-shaped surf is real, but you need the storm track to line up.
