The Lowdown
Alright, let’s break down Oyster Bay over the next couple weeks.
Water temp is 62°F, which is a bit colder than usual for late summer – anomaly is -2°F, so you’ll feel that chill when you get out.
Oyster Bay is an exposed sandbar break, and it’s inconsistent – not the kind of spot you can count on every day. There’ll be long flat spells.
Friday 28 August: small stuff – 4ft south swell, 11-second period, moderate energy (825). Winds are light from the SSW, onshore. Pretty marginal, honestly.
Saturday 29 and Sunday 30 August: forget it. Wind is up from the WSW, cross-onshore and choppy. Sunday afternoon has 8ft SW swell with a 12-second period and strong energy (1616), but the wind is messing it all up.
Monday 31 August morning: 6ft SW groundswell, 12-second period, moderate-strong energy (1003). Still cross-onshore and fairly choppy. Not a winner.
Now here’s the standout – Tuesday 1 September morning. Clear skies, light ENE cross-off wind, 7ft SW swell, 11-second period, energy at 1010. That’s clean. That’s fun. This is the call for the first week. The break can get a crowd “sometimes,” so you might have company, but it’s worth it.
Wednesday 2 September is a beast – 13ft SW swell, 15-second period, energy through the roof at 7988. That’s huge, long-period groundswell. Only for experts. The sandbar will be a washing machine with that much juice – you want a reef or point break ideally. Wind is light, so the surface will be clean, but it’s big.
Thursday 3 September: strong SE winds and rain, poor. Friday 4 and Saturday 5: east swell, short 8-second period, 8ft to 12ft, strong energy (1766-2224), but clean wind. Still, short-period big swell is lumpy and tough – expert only.
Sunday 6 September: howling ENE winds near 50 mph, cross-off but messy, not worth it. Monday 7 September morning: drops to 4ft SW swell, 15-second period, light ENE cross-off, energy 1129. Clean but long period might make the sandbar a bit straighter.
After that, from Tuesday 8 September all the way to Saturday 12 September, it’s quiet. Small swell under 6ft, low energy (mostly under 700), and only marginal conditions. The second week is a washout – nothing to get excited about.
To sum it: Tuesday 1 September morning is your best bet – clean, fun, good energy. For the brave, Wednesday 2 September is a big-wave day. The rest is mostly for the patient or the optimist.

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.
