The Lowdown
Alright folks, Rusty here with a look at the next couple of weeks. It’s a real mixed bag for us, with some clean windows but plenty of rough stuff to wade through.
Right off the bat, we have to be patient. For the next couple of days, Oyster Bay is a write-off. Saturday afternoon (29 August) is a mess with strong cross-onshore wind and a weak, jumbled 3ft easterly swell. The energy is pathetic, barely registering. Then Sunday (30 August) is a complete no-go – big, choppy, and blown out.
The first real glimmer of hope comes Monday morning (31 August). The wind will be absolutely glassy – dead calm. The swell is a solid 6ft from the SW at 12 seconds, which is proper groundswell. The combined energy is a solid moderate. This is an intermediate call; the waves will have good shape and that longer period makes paddling out a bit easier with the lulls. The water temp is 62°, a solid 4° colder than usual for this time of year, so you’ll want the thick rubber.
After that little window, it gets ugly again. Tuesday (1 September) turns onshore and messy, and Wednesday (2 September) is a tease – glassy conditions with a massive 12ft SW swell, but that’s just too much for this sandbar. That’s expert-only territory. The rest of the first week and into the second is plagued by strong cross-shore and cross-offshore winds, keeping things bumpy or just plain messy.
The second week offers only fast, short-period windswell and heavy winds. Overall, the standout session is the Monday morning glass-off. It’s the only time everything lines up for a decent, clean surf.
Rusty.

Information about the Oyster Bay Surf forecast
The above surf forecast table for Oyster Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Oyster Bay can be found by selecting the local surf guide option on the grey menu. Our Oyster Bay surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Oyster Bay) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Oyster Bay may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Oyster Bay is 24 km (15 miles) from the city of Kruisfontein. If you plan a holiday in Eastern Cape (South), look for hotels and other accommodation in Kruisfontein. Kruisfontein has rooms for a wide range of budgets as well as car hire and transport links.
