Conditions at Honolua Bay in August
August: Still Locked in the Trade-Wind Shadow
August is not much different from July. The average swell height is still 1.3m (about 4ft) and the period is 9.0s. ENE swell accounts for 57.9% and E swell for 32.3%, with zero measurable N, NW, or NNW energy anywhere on the wave rose. That leaves Honolua in the shadow of the Hawaiian Islands for the only swell that actually works well on this exposure.
Trade winds remain strong and steady: ENE at 70.9%, NE at 21.6%, and ideal wind at 21%. There are occasional mornings when the trades relax, but the lack of north swell is the limiting factor. Water temperature peaks at 26.4°C and air averages 26.3°C, with rain around 1.12 mm/day. August is a month for patience, not for expecting great Honolua waves.
