The Lowdown
Alright, let’s get into it. We’ve only got one spot on the radar for the next couple of weeks, and to be honest, it’s a bit of a mixed bag. That’s Oyster Bay, and it’s a sandbar, so it needs the right conditions to really fire.
The first few days are looking a little rough. There’s some swell coming in, but the wind is just going to mess it up. We’re looking at onshore and cross-onshore breezes, which will chop things up. The swell is there, but it’s not going to be pretty.
The real standout is next Wednesday, August 12th. The morning is looking clean with a cross-offshore breeze and a 3ft SSW swell with a very long 20-second period. The energy is moderate at 1705, but the quality is what gets me. And then the afternoon goes glassy with a 4ft SSW swell at 18 seconds. This is the pick of the first week. For a sandbar, that long period might have it breaking a bit straight, but the clean conditions should make it work.
The Thursday and Friday after that are also worth a look. Thursday, August 13th, has a glassy dawn with a 6ft SW swell at 16 seconds. Clean and clean again on the afternoon with a 5ft SW swell. Friday, August 14th, has a 8ft ESE swell with a cross-off wind, but that period drops to 11 seconds, so it might be a bit less organized.
The water temp is 61°F and the anomaly is -5°F, which is much colder than normal. That’s a big deal, so bring the thickest suit you’ve got.
Now, from the 15th to the 18th, things back off. Wave heights drop, and it becomes less interesting. There are a couple of days with clean conditions on small swell, but it’s not really a highlight.
Then, hold on. The second week brings some serious size. August 19th and 20th are looking big, way big. We’re talking 12ft and then 21ft on the morning of the 20th. The combined energy is off the charts – 16541 and then 34391. That is a massive amount of energy. But, and this is a big but, that’s way too big for this spot. The wind and tide are favorable, but the swell is predicted to be too big for Oyster Bay. If you’re a top-tier expert, maybe, but for everyone else, this is a look-don't-touch situation. It’s promising, but so far out, you gotta take it with a grain of salt.
So, there you have it. The windows are narrow, but the clean windows on the 12th and 13th are the best on offer. The huge stuff at the end is just too much for this break.

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.
