The Lowdown
Alright, Rusty here. Let's take a look at what's cooking.
Honestly, the next week or so is looking pretty bleak. We've got a lot of strong, messy winds and lumpy, cross-onshore conditions making a mess of things. The one spot we've got to work with is Oyster Bay, and it's an inconsistent sandbar that needs everything to line up.
The only real light in the tunnel – and it's a good one – is the morning of Tuesday, September 1st. Oyster Bay should be pumping with a clean 8ft swell from the SW with a nice long 12-second period. The wind will be a light offshore from the NNW, keeping the faces clean for experienced surfers. The combined energy is massive at 1669, so there's plenty of power. Just be aware that with that size, this is strictly for the experienced crew; beginners will be in over their heads. Crowds are possible, but it might keep some away given the size.
The next real standout is also a morning session: Monday, September 7th. Oyster Bay looks glassy with an offshore wind and a 7ft swell from the S. It's a bit shorter period at 9 seconds, but with conditions that clean, it'll be fun and a lot more user-friendly than the earlier big swell. The combined energy is a solid 1633, so there's some push.
Between those two, there's a lot of junk. The afternoon of the 1st gets cross-onshore, and the 2nd of September sees a massive, dangerous 18ft swell but with strong winds that'll make it a washing machine. That's more of a kite-surfing setup than a paddle session.
The second week looks like it might settle down a bit. Tuesday the 8th and Wednesday the 9th of September look small and clean in the mornings, but the swell is weak and marginal. Not worth getting too excited about.
After that, the 11th of September shows some promise with a 7ft SW swell and cross-offshore winds, but it's a long way out, so take that one with a grain of salt.
So to wrap it up: if you're an expert, circle Tuesday morning, September 1st. For the rest of us, Monday morning, September 7th is your best bet. The rest of the window is pretty much a write-off for clean waves.
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.
