Conditions at Waikiki Beach in August
August: Trade Swell Still Dominates, but a Hint of Change
August mirrors July in many ways. Average swell height remains 5ft (1.5m), period 10.7 seconds, and the swell direction is dominated by E at 41.0%, ESE at 25.1%, SE at 13.3%, and ENE at 8.7%. The North Pacific storm track is still dormant, so there is no meaningful N, NW, or NNW groundswell. Most waves are in the 3.3-6.5ft (1-2m) range, with the E direction supplying a solid 20.6% of 5-6.5ft (1.5-2m) energy and 17.8% of 3.3-5ft (1-1.5m) energy.
The wind continues to be the main issue. ENE trades blow 83.2% of the time, and the ideal offshore S/SSW/SW window opens only 5% of the time. This keeps the surface chopped up and makes the trade swell less clean than the numbers suggest. On the bright side, water temperatures hit 26.6°C and air temperatures are 26.1°C, with only 1.07mm/day of rain. For the north-facing exposure, August is a waiting game.
