Conditions at Skeleton Bay / Donkey Bay in July
July: Prime-Time Skeleton Bay
July sits at the top of the winter swell curve alongside June and August. The average swell height is 1.5m (4.9ft), and the period peaks at 12.8s, the longest of the year. The swell window remains dominated by SSW at 23.8 percent and SW at 68.6 percent, while the height distribution shows a strong 1.5-2m (5-6.5ft) class at around 33 percent and a notable 2-2.5m (6.5-8ft) class at 11.3 percent. When the longer period southwest groundswell arrives, the NW-facing beach is fully exposed to its wrapping energy, and the sandbar can produce long, hollow, high-performance lefts.
Winds remain solidly offshore-oriented, with ideal surfing conditions 47 percent of the time. S and SSW flow combine for just over 36 percent of observations, while the destructive N-NW wind sector is again low at roughly 8 percent. Water temperatures bottom out at 13.1°C and air temperatures average only 16.6°C, so thick winter rubber is essential. However, the combination of heavy, long-period swell and clean offshore wind makes July one of the finest months of the year for serious wave riders.
