The Lowdown
G'day, Rusty here. Let's have a look at what's on the cards for Oyster Bay.
Straight up, this stretch is looking pretty average for a while. There's no surf worth paddling out for today, Sunday the 13th. The water's sitting at a slightly chilly 63° which is a bit colder than normal for this time of year. The wait will be until Monday morning the 14th. The early part of the week is the only real bright spot, with a window of clean, offshore winds on Monday the 14th. Swell is coming in at 8ft from the east with a short period of 10 seconds. The combined energy is strong (1719). That's going to be a bit much for learners, but for anyone with some experience, it'll be clean and fun. The wind is light and offshore from the northeast, so the waves will have a nice face to them. Keep in mind the east swell direction isn't ideal for this spot's optimum southeasterly direction, but it's the best we've got.
Monday afternoon sees the wind swing to a cross-shore and the quality drops off. From Tuesday the 15th through the rest of the week and into the following week, things get patchy. You'll see waves, but the wind is often cross or onshore, and conditions are generally marginal or poor. There's a consistent south-west swell running through this period, but the lack of good wind means it's mostly a write-off for a clean surf. The best of a bad bunch might be Saturday morning the 26th, with a 7ft south-west swell, cross-off wind and moderate energy (1489), but it's nothing to get too excited about.
Now, there is one huge standout in the long-range forecast. Saturday afternoon the 26th is looking like a big, powerful groundswell event. We're talking a massive 10ft south-west swell with a very long period of 16 seconds, and the combined energy is off the charts at 4124. The wind is cross-off from the east, which would be perfect. But here's the thing, the forecast is saying the swell is predicted to be too big for this break. At 10ft, this is purely for experts only, and even then, a long-period swell of 16 seconds can make a sandbar like Oyster Bay close out or break too straight. It's a shame because the conditions look incredible. Keep an eye on it, but it's one for the big-wave crew only.
Sunday the 27th morning sees the swell drop back to 8ft with a 14-second period, and the wind is still light cross-off. It's a solid, clean day for experienced surfers. Then Monday the 28th brings another monster 13ft swell, this time with a short 8-second period. The wind goes glassy in the afternoon, which is a treat, but again, the size makes it a specialist-only affair. The energy is very strong (4840). It's another "too big" call for this break.
So, the honest summary: don't get your hopes up for the next week. The standout is Saturday the 26th afternoon, but only if you're a seasoned charger looking for a serious session.
Rusty out.

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.
