The Lowdown
Alright folks, let’s get into it.
The next week and a half is looking like a bit of a mixed bag, so you’re gonna have to pick your moments. The standout by a long shot is the Friday morning (11th) session at Oyster Bay. That SW swell is a solid 6.2ft with a 13-second period, and the wind is glass. It doesn’t get much cleaner than that. This is the one to circle if you can make it. The energy is strong too, sitting at 1285.
The following Monday morning (14th) is also worth a look. The swell has shifted around to the east, coming in at 8.2ft with a 10-second period, and it’s light offshore. It’s going to be a bit more powerful, so only if you’re comfortable on a bigger wave. The energy is up there at 1820. Clean conditions but that one’s for the experienced crew.
After that, things get a little trickier. We've got a run of bumpy, windy afternoons and mornings with onshore or cross-shore winds that are just going to chop things up. Thursday morning (17th) looks magic again – glassy, 7.2ft of SW swell, 13-second period. That's another top-tier pick, but again, it’s solid size.
Now, looking further out, there’s a big pulse of energy coming in around the 20th and 21st. The swell is forecast to be huge, over 11.5ft, with strong energy readings (3894 and 5665). But here’s the thing, it’s just too big for this spot. The wind might be favorable, and the sets will be pushing hard, but it’s going to be closing out and dangerous unless you’re a total charger. Keep an eye on it, but don’t get your hopes up for a clean, rippable day.
Overall, the start of the window is your best bet for quality. The rest is a waiting game.

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.
