The Lowdown
Alright, Rusty here. Let me break down what Oyster Bay's got cooking for us.
First off, the water is a cold 61°F, which is 5°F colder than normal for this time of year – that's a big difference. You'll feel it.
Tuesday morning (25th August) is a write-off. You've got an 8ft SW swell, but the wind is cross-onshore at 12 mph, making it choppy and nasty. Afternoon cleans up a touch with a 6ft SW groundswell but it's still only marginal.
Wednesday the 26th is the big one, but with a warning. The swell pumps up to 10ft from the SSW, with a long 16-second period – that's serious groundswell energy. Wind is cross-off from the east, so it looks clean. But listen, 10ft at a sandbar is heavy. Combined energy is 4527, which is massive. Only experts should consider it, and a long-period swell like that can make a beach break dump straight.
Thursday the 27th is the pick of the bunch. Swell drops to 7ft from the SSW, still 12 seconds, and the wind is light cross-off in the morning. Perfectly clean. This is excellent for experienced surfers, and the morning glass is the best you'll see in this forecast. Friday the 28th is smaller at 4ft to 4ft from the south, with offshore winds in the afternoon – good for a longboard.
From Saturday the 29th, it all goes south. The wind turns onshore and stays that way for days. Swell gets big again – up to 21ft – but with strong cross-onshore winds, it's just a messy, lumpy beast. Not your day.
You get another window around the 5th and 6th of September. The swell is a solid 13ft to 15ft from the east-southeast, and the wind shifts cross-off from the east again. It cleans right up. But that's a 15ft wave at Oyster Bay. Combined energy is over 6000, so it's packing a punch. For the brave and the skilled only.
If you're not charging massive swell, your session is Thursday the 27th of August, or the small clean waves on the 28th. Everything else in the second week is either blown out or way too big for a good time.
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.
