The Lowdown
Alright, Rusty here, let’s get into it.
We’ve got a bit of a slow start ahead of us at Oyster Bay. The first few days are a write-off. Saturday the 29th and Sunday the 30th are a complete mess with strong cross-onshore winds and lumpy, poor surf. You won’t want to be out there. The water temperature is sitting at 62°, which is a solid 4° colder than what’s normal for this time of year, so you’ll be wanting a thicker wetsuit.
The first real glimmer of hope comes on Monday the 31st. The morning is looking special. The wind goes glassy, dead calm from the ENE, and we’ve got a clean 6ft SW groundswell rolling in with a 12-second period. The combined energy is moderate at 1003. This is excellent for experienced surfers – the swell is a bit over 5ft, so it’s not for the beginners, but the conditions are clean and the sets will have some punch. This is your standout session for the early part of the week. The afternoon does get a little bumpy with a light cross-onshore, so get out early.
The middle of the week gets tricky. Tuesday the 1st is messy with onshore wind, and by Wednesday the 2nd, the swell really cranks up. We’re looking at an 12ft SW swell in the morning and 10ft in the afternoon. The combined energy is massive – 3629 and 2870 – a strong system. The winds are light and cross-shore, but this is way too big for Oyster Bay. It’s only for experts, and even then, it’s a big, powerful wave. The forecast says it’s too big for this break, so I’d be very cautious.
Thursday the 3rd and Friday the 4th are blown out again with strong winds and rain, but we see a shift on Friday afternoon. The wind goes cross-offshore from the E at 19 mph, cleaning up the 7ft SSW swell. The combined energy is still strong at 1737. It’s a marginal call, but it could be clean and workable. Saturday the 5th is similar, with clean but strong winds, so it’s a bit of a battle.
Now, hold on to your board. Sunday the 6th of September is a proper standout. Morning gets a 8ft SW groundswell with a very long period of 16 seconds. The combined energy is a massive 3221. The wind is light cross-off from the ENE, so it will be clean. This is a long-period groundswell, so it will be lining up nicely at the point, but it might be a bit too straight for the beach. The afternoon is also solid with a 7ft, 15-second swell. This is a serious day for the experienced crew.
After that, it’s a rough patch. A strong Westerly wind blows Monday and Tuesday the 8th and 9th, making a mess of things. Then we get another huge event on Thursday the 10th of September. The swell is predicted to be 15ft from the East with a 10-second period. The combined energy is off the charts at 7651 in the afternoon. The wind is cross-offshore and clean. This is a monster swell and it’s too big for Oyster Bay. Only for experts, and you’d need to know what you’re doing.
The final weekend, Saturday the 13th, looks like another good bet. The swell backs off to a clean 7ft from the SW with a 14-second period, and the wind is dead calm, glassy. Combined energy is moderate at 1758. This is excellent for experienced surfers again. A beautiful way to end the forecast.
Bottom line: The best windows are Monday morning the 31st of August, and then Sunday the 6th and Sunday the 13th of September. The 6th has the biggest, longest-period swell, but the 13th is glassy. Get out there.
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.
