The Lowdown
Right, I’ve had a look at the charts for Oyster Bay, and I gotta say, it’s a bit of a frustrating outlook. This spot is a sandbar, and it’s known for being inconsistent, which is a real shame because the potential is there. The water is sitting at 64°, which is a bit colder than normal for this time of year, so you’ll be wanting a decent wetsuit.
The first window of opportunity is a bit of a wait. We’ve got a few days of messy, lumpy conditions with onshore winds and poor surf quality right through until the 17th of July. Honestly, not one to paddle out for.
Then, finally, on Friday the 17th, the afternoon shapes up nicely. We’ve got a clean 8ft swell from the SW, with a light cross-offshore breeze, and the period is a solid 11 seconds. The combined energy is a decent 1305, so there’s some push there. This is the best looking window for a paddle. It’s a standout for the whole period, but you’ll want to be an experienced surfer; it’s not a beginner wave. Keep an eye on it, as crowds can be a thing here.
The rest of the week is a write-off, with strong onshore winds and choppy seas. The 21st of July sees a massive 13ft SW groundswell rolling in, with a very long 14-second period and clean offshore winds in the morning. It’s a monster, but it’s too big for this break. The energy is through the roof at 6436, which will make it a washing machine for most. Save that for the experts only.
The 25th of July, Saturday, offers another chance. A 10ft SW groundswell with a long 15-second period and clean offshore winds from the NE in the morning. Again, the combined energy is a beast at 3716, and it’s a big, powerful swell. For the experienced crew, it’s a goer, but for the average joe, it’s a spectacle. The 29th of July has a similar story, with an 12ft swell but cross-shore winds, making it less clean.
So, to be honest, the standout is that Friday the 17th afternoon session. It’s the only time the size, wind, and conditions really line up for a good, clean surf. The rest of the window is either too big, too windy, or just plain messy.

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.
