The Lowdown
G'day, Rusty here.
Alright, look, the next couple of weeks at Oyster Bay is a real mixed bag. We’ve got a lot of size on the way, but the wind is gonna be a pain in the arse for most of it. The water is sitting at 65°F which is pretty much bang on average for this time of year, so no surprises there.
The first real look we get is on Saturday, the 5th of September. It’s not a classic, but it’s the calm before the storm. The morning will see a 5ft swell from the SSW with a period of 11 seconds – that’s a nice little groundswell, giving it some shape. The wind is out of the East at 16 mph, a clean cross-offshore breeze, so the face will be smooth. The combined energy is moderate at 745. It’s a small, clean option for a Saturday morning.
Sunday the 6th is where things get serious, but it’s not for the faint-hearted. The morning has a 7ft SSW swell, but the period is a massive 20 seconds – that’s very long-period groundswell. It’ll be powerful and straight, but the wind is still a clean cross-off at 22 mph. The energy is strong (4141). The afternoon though, it pumps up to 12ft from the same direction with an 18-second period. The combined energy hits 7184. That’s a lot of water. For a sandbar like Oyster Bay, it’s just too big for most and will be a challenging, shifty mess. Only for the very experienced crew on the biggest boards, and even then, it’s a gamble.
The real standout window is Tuesday, the 8th of September. The morning is absolute magic. The swell drops to a more manageable 4ft from the SW, with a 13-second period. That’s a clean, lined-up groundswell. The kicker? The wind is completely glassy – 0 mph from the NE. The combined energy is moderate (1041), but with conditions like that, it’ll be the best session of the run. It’s a good, clean bank for an intermediate surfer.
After that, it’s a bit of a write-off for a few days. The wind turns onshore and messy, and the swell stays up. Wednesday the 9th has a glassy morning, but the swell is a weak 4ft from the East with a short 9-second period, so it’s small and a bit weak.
Then from Thursday the 10th right through to the end of the second week, it’s a battle. The wind is mostly a strong cross-onshore or onshore, and the swell is all over the place. The 15th of September sees another 12ft SSW swell, but with a fresh cross-offshore wind, it’s just too big for this break again. The 17th of September has a 10ft SSW swell with a clean offshore wind from the NNE, but again, the size is the issue.
Honestly, if you’re looking to paddle, aim for Tuesday morning, the 8th. That’s your one true gem. The rest of the time, with that much wind and size at a sandbar, it’s looking more like a kitesurfing spot than a surf spot.
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.
