The Lowdown
Alright folks, Rusty here. Let’s get into it for Oyster Bay.
First up, the water at Oyster Bay is running a bit colder than usual for this time of year, sitting at 63°F, which is about 3°F below the norm. Nothing crazy, but you’ll feel that nip.
The 16-day window kicks off with a slow start. Monday the 7th has some swell, but it’s messy with a strong cross-offshore wind at 19 mph, and the energy is high (2790) but the quality is just not there. We’re looking at a couple of days of waiting.
The real standout is Tuesday morning, the 8th of September. That’s the one to circle. The wind goes glassy, WSW at just 3 mph, and we’ve got clean 4ft swell from the southwest with a 13-second period. The combined energy is a solid 1062, and with the wind off the land, it’ll be smooth and lined up. This is the best on offer for the whole outlook – perfect for intermediate surfers who want clean, fun waves without the crowds getting too heavy (though it can get busy here sometimes).
The next good window is Sunday the 13th. Morning sees a clean offshore breeze from the NNE at 9 mph, with a beefy 6ft south-west swell running on a 15-second period. That’s a long-period groundswell, so expect those waves to have real power and shape, especially at this sandbar setup. Energy is high at 2405. The afternoon stays clean with a cross-offshore wind. This one’s for the experienced crew.
Saturday the 12th has a pulse of 8ft swell from the ESE with a short 8-second period, but the wind is howling cross-off at 28 mph. Too blown out for a good paddle. The setup might be better for kite surfers that day.
After the 13th, things get messy. There’s a big, powerful swell on the 16th and 17th, with heights over 8ft and energy up to 5530, but the wind is onshore and strong – 22 to 28 mph. That’s expert-only, and even then, it’s going to be a washing machine. We’ve got a run of poor conditions from the 14th right through to the end of the window, with strong onshore winds and lumpy, blown-out surf. The 22nd drops to tiny 2ft with barely any energy (52), so that’s a complete write-off.
So, to sum it up: Tuesday the 8th is your gold star session – glassy, clean, and fun. Sunday the 13th is the heavy hitter for the experienced. Everything else is either too windy, too big, or too small. Keep your eyes on the sky for those two windows.

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.
