The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up at Oyster Bay.
If you’re looking to get wet, you’re gonna have to be patient. The next week or so is a mixed bag. We’ve got some serious size coming through, but a lot of it is going to be blown out or just too damn big for this sandbar. The first real window of opportunity doesn’t open until Friday the 24th. There’s a massive, very long-period SSW groundswell building, but it’s a double-edged sword.
The standout by a long shot is Friday morning, July 24th. We’re looking at a 13ft SSW groundswell with a period of 16 seconds. The combined swell energy is a massive 8077, which is some serious power. The wind is light and offshore from the north, so it’s going to be clean. That’s the good news. The bad news is that 13ft is massive for any break, and Oyster Bay is a sandbar. This is one for experts only, and even then, you’d better be on your A-game. The long period will make it bend and unload, but it might be a bit too straight for the bar. Friday afternoon is still huge at 12ft, but the wind goes cross-off from the east, keeping it clean.
Saturday the 25th is a good shout for the experienced crew. Morning sees a still-significant 8ft SW swell with a 14-second period, and the wind is light cross-off from the northeast. You’ll have clean conditions. The water temp is sitting at 65°, which is about 2° cooler than average for this time of year, so nothing too wild, just a slight chill.
After that, the quality drops off. We get a mix of onshore winds and messy conditions through the end of July. There’s another big pulse on the 28th and 29th, but it’s again over 10ft and the wind isn’t as clean. Not ideal for a sandbar.
The next real chance comes on Saturday, August 1st. The morning session looks good with a 7ft SW groundswell and a 13-second period, with a light offshore from the NNE. That’s clean, manageable size, and should offer some decent walls. Sunday the 2nd morning is also worth a mention, with a 6ft SE swell and a solid offshore from the NNE, but the period is a shorter 10 seconds, so it’ll be a bit more junky.
After the 1st of August, the energy drops right off. By the 3rd, we’re down to 3ft waves with onshore wind, and it just gets weaker and messier from there. The forecast fades out into a flat spell.
So, to wrap it up: if you’re an expert, the Friday the 24th morning session is the big one. For the rest of us, Saturday the 25th morning and Saturday the 1st of August morning are your best bets for clean, solid waves.
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.
