Conditions at Makaha in August

August: Winter Peak Continues

August remains deep in the southern winter swell window, with 5ft (1.5m) average height and a 13.2s period. The SSW direction is still responsible for 85.9 percent of the energy; SW contributes 6.9 percent, and S adds 6.0 percent. One rare but notable feature is a small 0.1 percent of swell in the massive 8ft+ (2.5m+) category - proof that even the biggest Southern Ocean lows can find this coastline. Most of the time, though, Makaha is seeing 3-6ft (1-2m) surf, with 39.6 percent in the 5-6ft (1.5-2m) range and 8.9 percent in the 6-8ft (2-2.5m) range. Winds remain stubbornly onshore: 81.6 percent from due S and 15.1 percent from SSW; 21.3 percent of the wind blows 20-30kph. Water temperatures cool further to 16.3°C, and air temperatures average 16.9°C. It is big and powerful, but quality depends entirely on finding brief wind lulls.
