The Lowdown
Alright folks, Rusty here. Let’s look at what we’ve got on the cards for Oyster Bay over the next couple of weeks. It’s a bit of a mixed bag, but there are a few windows that’ll get the heart pumping.
Right off the bat, the water temp is a chilly 61°, which is nearly 5°F colder than what’s normal for this time of year, so a 4/3 wetsuit and booties are a must. The surf kicks off on Thursday the 13th, but it’s nothing to write home about. Thursday morning has a 4ft SSW swell with a very long period of 20 seconds—loads of energy (2591), but the cross-off NE wind at 16 mph makes it a bit of a battle. The call is only marginal, so I’d probably give it a miss unless you’re desperate for a paddle.
Friday the 14th is where it starts to get interesting. The early session has clean 5ft SW swell with a 15-second period. The wind is offshore from the NNE at 12 mph, and with moderate energy (1370), it’s a proper standout for experienced surfers. The afternoon stays clean with a gentle offshore, dropping to a 5ft SW swell—still quality. This is the best on offer early on.
Saturday the 15th is a real treat for the early birds. Glassy conditions with a WNW breeze at just 3 mph and a clean 4ft SW swell (14-second period, 667 energy). That’s a beautiful morning session for the intermediates out there. The afternoon gets blown out by a cross-off easterly, so make the most of the dawn patrol.
Sunday the 16th and the start of the week turn ugly. Small, weak, and choppy with onshore winds. Not worth the drive.
Monday the 17th has a 7ft SSW swell (13 seconds, 1706 energy), but it’s cross-onshore from the west, so the surface is messy. There’s a period of poor surf dragging on through until Thursday the 20th, with strong winds and lumpy conditions. The swell is solid, but the wind is ruining it.
We’ve got a long gap of poor quality until Friday the 21st of August. That morning is a gem: glassy conditions, clean 7ft SW swell with a 12-second period (1103 energy). It’s only for the experienced crew as it’s a touch solid, but with the wind dead calm, it’ll be worth the wait.
The real standout is Saturday the 22nd of August. The morning shows a 10ft SW swell with a 14-second period—massive energy (3339). The wind is light and cross-shore, but this swell is simply too big for Oyster Bay. This is strictly for the experts only; everyone else should sit this one out. The afternoon gets messy with strong cross-onshore winds.
Things settle back to a more manageable 5ft to 6ft range the following week. By Tuesday the 25th, we’re back in clean territory. The afternoon has a light offshore breeze with a 5ft SW swell (12 seconds, 1147 energy)—another solid call for experienced surfers looking for a clean session.
Thursday the 27th afternoon brings a 7ft SW swell (13 seconds, 1956 energy) with onshore wind, so again it’s marginal.
The final call on Friday the 28th is another monster 10ft SW swell (14-second period, 3457 energy). It has favorable wind and tide, but the size makes it a big-wave day only. The crowd profile at Oyster Bay says “sometimes” busy, so for those standouts, expect company.
All up, the best windows for clean, quality waves are Friday morning the 14th and Friday morning the 21st. The big stuff on the 22nd and 28th is for the hardcore crew only.
Stay safe, stay stoked.

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.
