The Lowdown
Alright folks, Rusty here, giving you the rundown for Oyster Bay.
We’ve got a mixed bag coming our way over the next couple of weeks. Things start off promising enough, but we’ll have to wade through some average and messy conditions before the real juice shows up later on. The biggest standout looks to be two separate windows, one for the experienced crew and another for just about everyone else.
The first glimmer of hope is on Tuesday afternoon, September 8th. The water temp is sitting at 59°, which is a whopping 7° colder than normal for this time of year – that's seriously cold, so you’ll be wanting a thick wetsuit for sure. The surf is 4ft from the SW with a 12-second period, so there’s some decent energy in the water (combined energy of 667). It’s clean with a light cross-off breeze, so it’s a nice, clean start. Wednesday the 9th is worth a look too, with a 3ft SW groundswell (11 seconds) in the morning under clear skies and a light cross-off wind.
We then hit a flat, messy spell from Thursday the 10th right through to the following Sunday the 13th. The wind gets strong and onshore, making things choppy and unappealing. It’s a bit of a write-off for paddling. The swell does build but the quality is poor, so you’re better off waiting.
Now, here’s the first real standout for the experts. On Monday morning, September 14th, things get interesting. The wind goes glassy – dead calm – and the swell is a solid 10ft from the east. However, that’s over 8ft and the forecast is clear that it’s too big for this break and really only for the experienced. The period is a short 9 seconds, so it will be a bit crumbly at a beach break, but the glassy conditions are a rare treat if you’ve got the skills.
The following week gets a bit more stable. Tuesday morning, September 15th, looks clean with a 6ft E swell (11 seconds) and a light cross-off breeze, offering a more manageable option. Thursday afternoon, September 17th, is another high point: a 7ft SW swell (12 seconds) with clean, cross-off winds and excellent conditions for experienced surfers. Oyster Bay does get busy sometimes, so you might have company.
The biggest event of the whole run is on Monday, September 21st. We’re looking at a serious 13ft SW groundswell (18 seconds) in the morning, dropping to 12ft in the afternoon. This is huge – combined energy is a massive 9838 in the morning. The winds are cross-off and clean, but this swell is well above 8ft. It’s an expert-only zone, no question. Right after that, Tuesday morning the 22nd is still big at 8ft SSW (14 seconds) and clean, again excellent for experienced surfers.
After that, it’s all downhill again. Wednesday and Thursday the 23rd and 24th see messy, onshore winds and even bigger, unruly swell. It’s not worth it.
So, to wrap it up: the two true standouts are Monday the 14th for the glassy, oversized east swell (strictly expert), and Monday the 21st for the huge, clean SW groundswell (again, expert only). For the rest of us, keep an eye on Tuesday the 8th, Wednesday the 9th, Tuesday the 15th, and Thursday the 17th for some cleaner, more manageable waves.

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.
