Alright, surfers, Rusty here. Let's get into it. The next 16 days are a real mixed bag for us. We have some serious, powerful swell on the way, but it's going to be a bit of a waiting game for the right conditions.

The main focus is Oyster Bay. It's a sandbar, and it's inconsistent, so it doesn't fire all the time. When it does, it can be magic, but it can also be a total beast. The water temp is about average for the time of year, so nothing to stress about on that front.

We've got a big, powerful SSW groundswell rolling in on Friday the 10th and Saturday the 11th of July. We're talking chest to overhead-plus at 10ft to 12ft, with a long period of 12-13 seconds. The wave energy is strong to very strong (4121). But here's the catch: it's simply too big for this break. The sets will be closing out or just too heavy. The wind on Friday is a bit of a mess, too. So, not the one.

Sunday the 12th the swell starts to drop, but it's still a solid 5ft to 6ft from the SSW. The combined energy is still moderate (1392). The wind is cross-off in the morning, keeping it clean, but the quality is only marginal. It's a wave for the keen, but not a standout.

The whole of the next week, from Monday the 13th through to Saturday the 18th, is a bit of a write-off. The swell is weak, the winds are messy, and the quality is poor. There's a few moments of cleaner conditions, but the waves are just too small or too wind-affected. It's a blank run of about 6 days.

Now, we get a massive spike again on Sunday the 19th of July. Another SSW groundswell, a beast at 10ft to 12ft, with a period of 13-14 seconds. The energy is extreme (3959). The wind is cross-off and clean, which is a beautiful thing to see. But again, the size is the problem. It's too big for Oyster Bay. This is strictly for experts only, and even then, it's a risk. The raw power is there, but the shape is going to be challenging.

The real standout, the one to circle on your calendar, is Thursday the 23rd of July. Early morning, we have a 8ft SSW groundswell with a very long period of 15 seconds. This is deep, ocean energy. The combined energy is strong (2561). The wind is a gentle cross-off, keeping the surface clean. The data says it's excellent for experienced surfers. This is the one. This is where the longer period will really shine, drawing up nice, lined-up waves. It'll be a bit of a paddle, but the sets will be worth it. Expect crowds here, as it's a rare, good day.

Then, we're looking at a massive, almost comical, 16ft SW groundswell on Saturday the 25th of July. The period is 16 seconds and the energy is off the charts (12572). It's glassy, but it's a total maelstrom. That's a boat day, not a paddle day. Forget about Oyster Bay for that one.

So, the best of the best is Thursday the 23rd. Get on it.

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.
