August: Peak Winter Size at the Cost of Wind
August is tied for the largest average swell of the year at 4.3ft (1.3m), with a period of 12.4s and ideal wind in just 73% of observations - the second-lowest of the year. The swell mix is similar to July: SSW 81.7%, S 16.4%, SW 1.9%. The percentage of waves in the 4.9-6.6ft (1.5-2m) range is 12.0%, and 0.3% reaches 6.6-8.2ft (2-2.5m), the most top-end energy of any month in the dataset. For bigger-wave surfers, these are the best waves of the year.
But the surface is the issue. S winds dominate at 82.7%, and 21.6% of all observations are southerly at 20-30kph, with a small 0.1% sneaking into 30-40kph. That creates bumpy, sometimes wind-affected conditions between the cleaner early-morning windows. Water is at its coldest, 17.4°C, air averages 19.8°C, and rainfall is essentially zero at 0.04mm/day. The potential is high; the stakes are wind.
