The Lowdown
Alright, Rusty here, let's talk about what's on the cards for Oyster Bay.
First up, the water is sitting at 61°, which is a solid 5° colder than what's normal for this time of year. That's a big anomaly, so you'll want a thick suit if you're heading out.
The next 16 days are a mixed bag. We've got a decent pulse of swell arriving but it's going to take a while to settle down. The first few days are a write-off, with poor conditions and choppy, onshore winds. Things get interesting on the morning of Thursday, August 27th. There's a clean 7ft SSW swell with a 12-second period, and the wind is a light cross-offshore from the NE at 9 mph. Combined wave energy is strong at 2902, so it'll have some push. It's a sandbar break that's inconsistent, but this morning window is the most promising start to the period. The swell is a bit much for beginners though.
The rest of that week deteriorates quickly. From Friday morning through to Tuesday the 1st of September, it's mostly onshore, choppy, and lumpy with poor surf quality. The swell is there, but the wind just ruins it. There's a window on the morning of Tuesday, September 1st with a 7ft SW swell, but the wind is cross-onshore, making it messy.
Now, for the standout. The morning of Wednesday, September 2nd is shaping up to be the best of the entire run. We're looking at a massive 13ft SW swell with a 14-second period, which is a proper long-period groundswell. The wind is light and variable from the E at 3 mph, and the forecast is calling for clean conditions. The combined energy is a very strong 6908. However, this is a sandbar break, and a swell this size is going to be way too big for most. This is strictly for experts only, and even then, it might be a beast. This swell is also too big for the break, so it's a real caveat.
The following week is a bit of a rollercoaster. Thursday the 3rd and Friday the 4th of September are blown out by strong onshore winds and rain, with huge, unsurfable swell. By the morning of Monday, September 7th, the wind finally swings offshore from the NNE at 9 mph, with a clean 6ft ESE swell. The period is 11 seconds, and the combined energy is moderate at 1481. This is a solid, clean option for experienced surfers, with a much more manageable size than the 13ft day.
The rest of the second week fades out. The wind swings onshore again, and the swell drops off. By the morning of Thursday, September 11th, we see another big pulse of SW swell, 10ft with a 11-second period, but it's too big for the break and the wind is onshore, so it's a no-go.
So, to wrap it up, the best bet for a clean, quality wave is the morning of Wednesday, September 2nd, but only if you're an expert and can handle a massive, long-period groundswell at a sandbar. The morning of Monday, September 7th offers a much more manageable, clean alternative. Everything else is either blown out or too big for the break.
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.
