The Lowdown
Alright, Rusty here. Let's get into it, yeah? It's been a bit of a wait, but we've finally got a window opening up. The first real chance to get wet is on Thursday, August 14th.
That Friday morning, August 14th, is the standout. Oyster Bay is the only game in town, and it’s shaping up to be a beauty. We’ve got a solid 5ft of swell coming from the southwest, and the wind is swinging offshore out of the north-northeast at a gentle 9 mph. That’s the kind of glassy, clean morning that gets you out of bed early. The combined wave energy is massive at 2324, so there’s plenty of power in the water. Since it's a sandbar break, and the swell is around 5ft, this is a good one for experienced surfers. The water temp is feeling about normal for this time of year, not too hot, not too cold. Keep in mind, Oyster Bay can be inconsistent, but when it lines up like this, it’s worth the gamble. The crowd can be there sometimes, so get in early.
The earlier part of the week is a write-off, with strong cross-off winds and messy, lumpy conditions. We’ve got a big gap of poor surf from the 11th through the 13th. That Friday afternoon stays clean with a light breeze, but the swell drops to 5ft.
Saturday the 15th and Sunday the 16th are a no-go, with onshore winds and choppy surf. The energy drops right off too, with readings down in the 200s and 300s.
Monday the 17th offers a bit of a look. The morning has a 5ft southwest swell with a light cross-shore breeze, and the energy is back up to 1132. It’s not perfect, but it’s a surfable option if you're desperate.
After that, things get rowdy. Tuesday the 18th brings strong onshore winds and a 10ft swell that’s just messy. This is more of a kite-surfing session than a paddle-surfing one. The following Wednesday the 19th and Thursday the 20th have clean conditions but the swell is big—8ft to 10ft—and the period is short, making it a challenge for all but the experts.
Then we hit another dry spell. Friday the 21st through to the middle of the following week sees mostly onshore winds and poor quality surf. The energy is weak, with readings like 144 and 135, which is basically nothing.
So, to wrap it up: your best bet is without a doubt that Friday morning, the 14th of August. The rest of the 16-day window is a mixed bag of too big, too windy, or too small. But that one morning? That’s the one.
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.
