Conditions at Green Bowls in September
September: Fading Trades, Focused Swell
September is a month in transition, still carrying a strong swell but showing signs of relief. The average swell is 2.0m (6-7ft) with a 14.3s period, and the direction is heavily focused out of the SSW at 71%, with S contributing 11%. That concentrated SSW fetch is perfect for a south-facing coastline like Green Bowls. The problem remains wind: ESE and SE each sit around 37%, and ideal wind only 2%. The trades are starting to weaken, though, and the wind rose shows more light SSE/S/SSW flow, meaning the ocean surface may glass off more often, especially early and late. Water temp is 26.3C, air 25.8C, and rain stays minimal at 1mm/day. Keep an eye on the tail end of the month.
