The Lowdown
Alright, folks, Rusty here. Let’s chew the fat on what’s coming.
We’ve got a bit of a mixed bag over the next couple of weeks. The first few days are a washout, so don’t bother paddling out until Friday morning. That’s when the fun starts. The standout period looks to be Friday the 14th through to the start of the following week, with a couple of other promising windows further out, though those are a bit more of a long shot.
Oyster Bay (sandbar) is the only spot in play, and it’s inconsistent, so you’ve got to be patient. The water temp is about average for this time of year, nothing special.
The first real surf arrives on Friday morning, August 14th. The swell is a solid 5 ft from the SW, with a nice long period of 15 seconds – that’s proper groundswell energy. The wind is a clean offshore from the NNE, making for some excellent conditions. This is the pick of the early window. The wave energy is moderate (1370). Friday afternoon eases to 4 ft but stays clean with a gentle offshore.
Saturday the 15th is a step down – the swell drops to 4 ft and the wind turns cross-on, making it a bit messy. Sunday through Tuesday the 18th is pretty much a write-off with small, weak, choppy slop.
Then we get a blip on Monday morning, August 17th – the swell is tiny at 3 ft from the E, but it’s glassy. If you’re desperate for a splash, it’s there, but it’s ordinary.
The next real highlight pops up on Monday, August 24th. The morning looks excellent for experienced surfers: 6 ft of SW swell with a 14-second period, and a clean cross-off breeze from the E. Wave energy is strong (1378). This is a solid session for those who know what they’re doing.
The final standout is on Friday morning, August 28th. Another clean, cross-off morning with a 6 ft SW swell and a 15-second period. The wave energy is strong (1732). It’s far out, so keep an eye on the charts, but it’s promising.
For the rest of the second week, there’s a fair bit of onshore wind and choppy conditions, especially from the 22nd to the 23rd where strong westerlies mess things up. The 26th has a glassy afternoon with 4 ft, but it’s not the best.
Bottom line: Friday the 14th morning and Monday the 24th morning are your best bets. The 28th is a long-range maybe. Don’t get your hopes up for the days in between.
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.
