The Lowdown

Alright, let’s get into it. The next couple of weeks around Oyster Bay are a bit of a mixed bag. We’re starting off with some solid groundswell on the way, but the wind is going to be a problem for a few days. The real standout, for those who are patient and experienced, is shaping up towards the end of the first week and then again late in the second week.

Right now, from Sunday the 9th through to Tuesday the 11th, the swell is pumping in at 10 ft, but it’s coming from the south and southwest with a cross-onshore wind. The combined wave energy is massive—between 2000 and 3000 (2973) on Sunday—but the conditions are just poor. It’s messy, choppy, and not worth paddling out for. The water temperature is 61°, which is 5° colder than usual for this time of year, so you’ll want a thick suit.

The first real chance of anything decent comes on Tuesday afternoon, the 11th. The wind swings to the east-northeast, becoming a cross-offshore, and the swell drops to 6 ft from the SSW with a period of 12 seconds. The combined energy is still high (1587), but it’s clean. It’s a marginal call, but if you’re desperate, it might be worth a look.

Things start to look better on Friday morning, the 14th. That’s the pick of the first week. The wind is offshore from the north-northeast at 12 mph, the swell is a solid 5 ft from the southwest with a long 15-second period, and the combined energy is 1906. The conditions are described as excellent for experienced surfers. The wave direction is a good match for the break’s optimum. This is a real standout for those who can handle it. The swell is over 5 ft, so it’s not for beginners, but it’s a clean, powerful groundswell.

Saturday afternoon, the 15th, is also worth a mention. The wind goes light offshore from the north at 6 mph, the swell is 4 ft from the southwest, and the period is still a nice 14 seconds. The conditions are forecast to be very good. It’s a bit smaller, but it’ll be clean and fun.

After that, the window closes up. From Sunday the 16th through to Thursday the 21st, it’s mostly poor or marginal. The wind goes cross-onshore, the swell direction shifts to the east, and the quality drops right off. There’s a gap of about five days where it’s not really worth it unless you’re just desperate to get wet.

Then we get to Sunday the 23rd of August. This is the other big standout, and it’s a long-range call, so keep an eye on it. The morning is small but clean, with a 1 ft, 18-second period SSW groundswell and light cross-offshore wind. The combined energy is low (261), but the conditions are good.

But the real winner is Sunday afternoon. The swell jumps to 10 ft from the southwest with a 15-second period. The combined energy is a massive 3866. The wind is light and cross-shore from the east-southeast at 6 mph. The report says the wind and tide are favorable, but the swell is too big for this break. This is for experts only. The water is still cold, but the power in that swell is something else. If you’ve got the skills and the board, this is the session to aim for. Crowds are possible at Oyster Bay, so get there early.

Monday the 24th is similar, with 10 ft to 8 ft swell from the southwest, but the cross-onshore wind makes it a bit lumpy. Still powerful, but not as clean as Sunday afternoon.

So, to wrap it up: Friday the 14th morning is your best bet in the first week, and Sunday the 23rd afternoon is the big one for the second week. Both are for experienced surfers. The rest of the time, it’s a waiting game.

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.
