Conditions at Wilderness in August
August: Late Winter, Still Plenty of Punch
August continues the winter theme, but the wind field becomes more westerly. Offshore flow drops to around 29%, led by NNW at 13.9% and NW at 7.8%, while W and WSW climb to 10.0% and 9.7% respectively. Those westerly winds can add a cross-shore texture to the peaks, so the cleanest conditions will come when the N/NNW component is strong and the W/SW energy is not too dominant. The average swell data remain flat, but late winter is still prime time for long-period S/SW groundswell. Water temperature is coldest at 15.6°C, air averages 14.0°C, and rainfall peaks at 1.54 mm/day. Look for the morning hours after a cold front passes.
