August: Last Breath of Summer, First Hint of Autumn
August is a low-energy month with one eye on the horizon. Average swell heights are around 3ft (0.9m), periods increase slightly to 8.8s, and the S/SSW/SW window delivers about 11% of observations - more than July but still small. The energy in that window is centred on 1.5-5ft (0.5-1.5m), with occasional 6ft-plus (1.8m-plus) sets. The dominant wave directions remain WSW, W and WNW, meaning many days pass without any meaningful south swell reaching the beach. Offshore flow remains reliable: N/NNE/NE/NNW winds account for around 27% of observations, and ideal surf conditions occur 30% of the time. When you find a SW pulse during a summer trade-wind setup, the surf can be surprisingly clean, just not very big.
Water temperature peaks at 22.6°C, air temperatures average 22.8°C (min 18.2°C, max 25.9°C), and precipitation is still low at 1.15mm/day. August is prime time for easy-going sessions, and it can provide an early taste of autumn when the first southerly lows begin to stir.
