September: More Size, More Chaos
September delivers the highest amount of 0.5-1m swell so far - 37.2% of the SSW distribution, with a small 0.1% in the 1-1.5m range. The average height is 0.5m (1.5ft), and the period drops to 10.7s, making the waves a little more punchy and disorganized. This is the heart of the rainy season, with 8.03mm/day of rain and an air temperature of 26.9°C. Water temperature stays at 29.2°C. The wind field turns more complex: S winds are 11.6%, SSE 10.3%, SSW 7.2%, while NW at 20.3%, WNW at 13.1%, and NNW at 11.1% still offer offshore windows. The 15% ideal-surf number remains decent, but you will need to pick your windows carefully - when the sea breeze kicks in, the onshore south wind can chop things up quickly.
