Alright folks, Rusty here. Let's talk about what's on the cards for Oyster Bay over the next couple of weeks. It's a bit of a mixed bag, so let's get into it.

The water at Oyster Bay is sitting at 64°, which is about a degree and a half colder than average for this time of year. You'll feel that nip in the air, so don't forget a thick wetsuit.

Right now and through the first week, it's a tough watch. We've got a persistent cross-onshore wind messing with everything. The swell is there, but the quality is just not there. On Tuesday the 7th, we're looking at 7ft of SW swell but with a 16 mph cross-onshore, it's choppy and poor. That combo of slop and wind continues mostly through to Sunday the 12th, with swell sizes fluctuating between 4ft and 12ft, but the wind just ruins it. The wave energy is moderate to very strong—for instance, Thursday morning the 9th we're seeing a combined energy of 4236—but it doesn't mean a thing if it's blown out. The 12th, Sunday afternoon, we do get a clean 4ft SSW swell with cross-offshore winds, but with only a marginal score, it's just a teaser.

Now, there's a real moment of hope. On Monday the 13th, look out. The morning brings a glassy 7ft ESE swell with that classic groundswell period of 10 seconds and light NNW winds. That is your standout morning. The combined energy is 966, which is moderate, but the clean, glassy conditions will make up for it. If you can get out there, that's the best of the first week. Tuesday the 14th also looks clean, with 7ft of SE swell (9-second period) and offshore winds in the morning, and cross-offshore in the afternoon.

After that, the outlook gets a bit gnarly again. We see a pulse of bigger, more powerful swell rolling in from Friday the 17th onwards. For example, Friday morning the 17th we're looking at a 10ft SW swell with a 13-second period, clean offshore winds, but the comment says it's too big for this break. The combined energy is strong at 2921, but for a sandbar like Oyster Bay, that's expert territory only. Saturday the 18th is similarly big at 10ft, though the wind is cross-shore. The swell hits 13ft on the 19th and 13ft on the 21st with strong energy (6085 on the 21st morning), but the wind is onshore and messy. Those big days will be for the hardcore crew or maybe the kite surfers, honestly, because the sets are going to be heavy and tough to paddle into, especially with that short-period wind swell energy mixing in.

For the second week, if you're looking for a clean window, Tuesday the 14th is your best bet. Monday the 13th is the real gem because of the glassy conditions. The rest of the run is dominated by big, unruly swell and strong winds.

There are gaps where conditions are just plain rough, but if the wind backs off, those bigger swells from the SSW and SE could turn it on. Keep your eye on the forecast.

Stay stoked, and I'll see you in the water.

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.
