The Lowdown
Alright, Rusty here, and I’m looking at Oyster Bay for the next couple of weeks. It’s a sandbar that’s exposed and inconsistent, and it can get crowded when it’s working. The water is 63°, which is a bit colder than normal for this time of year, so don’t forget the wetsuit.
We’ve got a slow start. Friday the 31st through Sunday the 2nd of August is not worth paddling out for. The wind is a stiff cross-off, and the swell is 5ft to 8ft, but the period is short and the energy is all over the place. The combined energy is over 1000, but it’s sloppy.
The first real window is Monday morning, the 3rd of August. The wind goes offshore from the NE with a light breeze, giving us a clean 6ft swell from the ESE at 11 seconds. That’s a groundswell with some punch, and the combined energy is 1215. It’s the best option early on, but the tide messes with it a bit. Tuesday the 4th and Wednesday the 5th are weaker, with shifting winds and a 8ft swell on Wednesday afternoon that’s cross-on and choppy.
Now, the second week gets wild. The 6th of August brings a massive 16ft SW swell with 13-second period, but the wind is a fresh cross-onshore. The combined energy is a huge 9166, so it’s pumping, but it’s a mess for a paddle. That’s kite-surfing territory. The swell stays big through the 7th, 8th, and 9th, holding at 10ft to 12ft. The wind is favorable on the 7th morning with a gentle offshore, and on the 8th morning it’s glassy. But the call says it’s too big for this break. 10ft at a sandbar is for experts only, and it’s a battle.
The absolute standout is Saturday morning, the 8th of August. The wind is glassy—dead calm—with a 10ft SW groundswell at 14 seconds. The combined energy is 3151. For the experienced surfer, that’s the dream. It’s going to be clean, powerful, and lined up. But it’s too big for anyone who isn’t an expert, and the crowds will be thick.
After that, the swell drops off fast. The 10th and 11th are messy with strong cross-on winds, and by the 14th and 15th, we’re down to 3ft and 2ft with very low energy (188). The 15th of August has a 5ft, 16-second groundswell, but the wind is light cross-on, and it’s not enough to get excited about.
So, if you’re a big-wave charger, the glassy morning of the 8th of August is your one. If you want something more manageable, the 3rd of August is your best bet.
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.
