The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s headed our way over the next couple of weeks.
First off, the water is sitting at 65°, which is pretty much bang on average for this time of year, so a standard wetsuit is all you’ll need.
The first real shot at anything decent doesn’t show up until the morning of Thursday, September 5th, but honestly, it’s a bit of a tease. We’ve got a 5 ft SSW swell on the cards, and the wind is a clean cross-off, so the surface will be nice. But the wave energy is weak (695), and this spot is inconsistent, so don’t go in expecting a feast. The real standout in this whole outlook is Sunday, September 7th.
Sunday, September 7th is the day to circle. The morning brings a solid 6 ft SSW swell with a very long period of 21 seconds. That’s proper groundswell energy, and the combined energy is a massive 3530. The wind is clean cross-off, so expect well-shaped, powerful lines. The afternoon jumps up to 10 ft, which is expert territory, but the energy rockets to 6454. This is a window for the crew who know what they’re doing. Because the period is so long, these waves will be better formed at the point than flattening out at the beach.
Then, we get a special treat on Tuesday, September 9th. The morning is glassy, with zero wind. The swell is a lap-friendly 4 ft from the SW with a 13-second period, giving it decent shape. The energy is moderate (1126). This is the pick of the bunch for the average surfer who wants clean, manageable waves. It will be uncrowded. This is one of the best windows in the whole forecast.
A bit of a gap opens up after that, with a bunch of lumpy, onshore, or just too-small days. The next potential highlight is a long way off, on Wednesday, September 17th. The morning shows a 4 ft S swell with a clean cross-off breeze and moderate energy (836). It’s promising, but a long way out, so keep your fingers crossed.
The rest of the run is a story of wind and chop. If you’re a kiter, the strong cross-off winds on the 6th and 7th might look interesting, but for a paddle, it’s a no-go.
Signing off, 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.
