August: Spring Signals and Mixed Winds
August is a holding-pattern month. Average swell remains 3ft (0.9m), period dips to 8.5s, and ideal wind falls to 46%. Swell directions include ESE (20.7%), E (19.2%), SE (17.9%) and ENE (12.9%), but the NNE (6.6%) and NE (6.2%) components are growing - a sign that more northerly swell is about to enter the mix.
The wind is more balanced between offshore S/SSW/SW (10.8%, 9.4%, 6.1%) and onshore NNW (13.7%), NNE (4.0%) and N (3.3%). This creates more variability: clean mornings with offshore flow, then lumpy afternoons as the northerly sea-breeze kicks in. Water temp hits the annual minimum around 20.2°C, air is 12.2-25.6°C, and rain is minimal at 1.46mm/day.
