September: Spring Swell With Tricky Winds
September still delivers serious swell - the average height is 4.3ft (1.3m) and period 10.5s - but the wind becomes the wildcard. S (29.3%) and SSE (26.5%) remain dominant, and 3-5ft (1-1.5m) waves account for 43.8% of the total. However, the E/ENE trade winds are stronger and more persistent, and ideal wind drops to 46%. This is a dawn-patrol month: score the clean morning wind before the sea breeze cranks onshore. Air temp is 21.7°C, rain picks up slightly to 2.90 mm/day and water temp is 20.5°C. The size is there, but you have to work for the quality.
