The Lowdown

Alright, Rusty here. Grab a coffee, we've got a long look ahead.

First up, Oyster Bay's water is sitting at 61°, which is a solid 5° colder than normal for this time of year. That's a big deal – you'll want a thick wetsuit, no doubt about it.

We start off with a little pulse of swell on Tuesday the 4th. The morning's the pick, with a clean 5ft SW groundswell at 12 seconds and a light offshore breeze. The water's got some serious energy behind it (1205), but it's a bit much for the average punter. Still, for the experienced crew, that Tuesday morning window is clean and inviting. The afternoon turns choppy and messy, so don't sleep in.

Wednesday the 5th is a bit of a tease. Morning brings smaller 3ft surf with a really long 15-second period – that's proper groundswell – and clean conditions. It's inconsistent, but those long-period lines will wrap in nicely at this sandbar. The afternoon jumps up to 6ft but gets chopped up by cross-onshore wind, so morning is the only game in town.

Now, pay attention. Thursday the 6th and Friday the 7th are where it gets serious – but only for the right crew. Thursday morning sees a 12ft SW swell (4802 energy) with light cross-onshore wind. That's a lot of water moving. It's too big for beginners, and honestly getting a bit maxed out for this spot. Friday the 7th morning, though, is a real standout. The swell drops to a still-chunky 8ft from the SW, the period is a solid 13 seconds, and the wind goes glassy – dead calm. That's as clean as it gets for a big day. Only experts need apply, but if you've got the skills, that Friday morning session will be etched in your memory.

From Saturday the 8th through to Monday the 10th, forget it. Strong winds, onshore and howling, with massive swell. It's messy, blown out, and dangerous. The bay turns into a washing machine. Not worth paddling out.

Tuesday the 11th and Wednesday the 12th see the swell drop to a still-juicy 10ft, but now it's coming from the SSE and SE. The wind swings offshore or cross-offshore, so the surface is clean. The period holds around 11-13 seconds, so there's plenty of push. But again, that's heavy water for a sandbar. If you're skilled and hungry, the mornings are your window.

Thursday the 13th morning might be the best of the second week. A 10ft ESE swell with a 14-second period and a light offshore breeze – that's a beautiful combination of size, direction, and wind. The energy reading is massive (6343). It's a fantastic wave, but it's a big, powerful groundswell that will jack up fast. Not for the faint-hearted. The afternoon backs off a little.

Friday the 14th morning is another good shout. 8ft from the ESE, 12-second period, light offshore wind, clean. Still a big day for intermediates, but much more manageable than Thursday. The afternoon turns onshore, so make the morning count.

The weekend of the 15th and 16th drops right off. Saturday the 15th has a small 5ft SW swell but the wind is messy. Sunday the 16th is tiny – 3ft – and not worth getting wet for, unless you just want to float.

Monday the 17th and Tuesday the 18th see another big pulse of SW swell push through, 12ft and 8ft respectively, but the wind is howling cross-onshore again. Total write-off. The bay will be a churning mess.

Finally, Wednesday the 19th brings a bit of hope. 7ft SW swell in the morning with a cross-offshore breeze, clean. The energy is moderate (1782), and the period is a nice 12 seconds. It's good, solid surf for experienced surfers – a fitting end to a wild forecast period.

Best on offer: Friday the 7th morning for the glassy, big-wave perfection, and Thursday the 13th morning for the raw power and clean offshore wind. Both are for experts only.

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.
