August: Best Summer Structure and Typhoon Pulse Potential
August is the standout summer month. The average period jumps to 9.0s, the longest of the year, and size ticks up to 4.5-5ft (1.4m). SSE, SE, and S swells fill the rose with 16%, 15%, and 16% respectively, and the E/ESE window remains active. While S/SSW/SW directions still dominate at around 41%, the increase in SSE/SE energy plus tropical cyclone pulses can create genuine Ohama surf. Ideal wind reaches 29%, the highest of the year, with WSW at 25% still controlling the sea breeze but lighter W/NW flows available in the mornings. Water temperature peaks at 27.1°C with air at 26.6°C. This is summer's most promising window for waves of consequence, particularly as typhoon lows begin tracking north and east.
