The Lowdown
Alright, let me break it down for Oyster Bay in imperial, the way a local would size it up.
Honestly, it’s a real mixed bag for the next couple of weeks. There’s some legit size on the charts, but the wind is gonna be a hassle most of the time, so you gotta be clever about when you paddle out. For the next seven days, it’s mostly messy, but there are a couple of clean windows if you’re picky. Water temp is about average for this time of year, no surprises.
First chance that’s half-decent comes on Sunday the 6th. It’s not a world-beater, but the morning is clean with a 6ft swell out of the SSW, and a super long period of 21 seconds. The energy is strong (3247), so there’s some push. It’s clean, but that wind is a strong cross-offshore. More of a ‘maybe’ than a must-paddle.
If you can wait, Tuesday the 8th is the real deal for the first week. Tuesday dawns glassy – dead calm – with a 4ft SW groundswell (13 second period) and moderate energy (1024). It’s a good call for experienced surfers, and the surface will be like a mirror. Just remember this spot is an inconsistent sandbar, and crowds are sometimes a thing, so you might have some company.
After that, the window slams shut. From the 10th through the 15th it’s mostly blown out, messy, or just too big. Some days (like the 14th) the swell tops 8ft, which is expert territory, but the wind is all wrong – cross-onshore and strong. The 11th is tiny at 3ft, so don’t even bother.
Now, for the long-range play. Friday the 18th is looking like the true standout. That morning is calling for a glassy start again, with an 8ft SSW swell, 11 second period, and strong energy (1783). It’s marked as excellent for big-wave guys. That’s the one to circle, but we’re talking more than a week away, so keep it on the radar but don’t count on it yet.
So, week one: hit Tuesday the 8th morning. Week two: watch Friday the 18th morning. The rest of it is either a blown-out mess or just not worth the drive.

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.
