Conditions at Hickory Bay in August
August: Late Winter Still Firing
August remains deep winter for Hickory Bay. The average swell height is 1.9m (6.2ft) with an average period of 10.8s, still well within long-period groundswell territory. The ideal wind percentage drops slightly to 45%, but NNW is again the leading wind direction at 12.6%, and NW/NNW offshore flow keeps many sessions clean. The E/ESE/SE/SSE swell window is arguably at its best, totaling around 40% of the wave energy with SSE at 10.8%, ESE at 10.1%, and E at 9.4%. That mix produces hollow, powerful waves on the SE-facing banks, especially when a Southern Ocean low parks east of the South Island. S/SSW swell still provides plenty of background energy. Water temps are the coldest of the year at 9.1°C and air temps average 8.6°C - winter rubber is essential, but the payoff is real.
