The Lowdown

G’day, it’s Rusty here. Let’s get straight into it for Oyster Bay. The next couple of days are looking pretty grim, so don’t get too excited just yet. We’ve got a bit of a wait on our hands before things start to clean up. There’s a long stretch of onshore slop and cross-on breezes making a mess of things until the middle of next week. Hang tight.

Saturday, August 15: The morning is the only real window this weekend. We’ve got a glassy 4 ft SW swell with a 14-second period, and the energy is sitting at 603. It’s clean, but it’s weak and the break is inconsistent, so you’ll be doing more waiting than riding. Water temp is 56°F, which is 10°F colder than normal – that’s crazy cold for this time of year, so make sure you’ve got the thickest suit you own. The afternoon turns into a cross-off breeze and it gets messy.

Sunday, August 16: Forget it. The swell bumps up to 5 ft but it’s crossed-up and choppy all day. Not worth paddling out.

Monday, August 17: Same story. A bit more size at 8 ft in the morning, but the wind is on it and the conditions are poor. The combined energy is up to 2198, but it’s not doing anyone any favors with that chop.

Tuesday to Wednesday, August 18-19: Still marginal. The morning of the 19th is the closest we get to a window, with a 8 ft SW swell and a cross-off breeze that cleans it up. But it’s a messy one and the break is inconsistent, so you’re rolling the dice. Conditions are average at best.

Thursday to Friday, August 20-21: Onshore junk again. The swell holds around 8-8 ft, but it’s choppy and lumpy. Not surfable in any meaningful way.

Saturday to Sunday, August 22-23: The wind kicks up hard, with a 22-25 mph cross-on blowing things out completely. Swell drops back to 6-6 ft then jumps to 10 ft on Sunday. Don’t even bother – this is kite-surf territory, not paddle-surf territory.

Monday, August 24: Here’s the big standout, but it’s a caveat-filled one. We get a serious groundswell – 12 ft at 16 seconds in the morning, with an energy reading of 5718. That’s a strong, powerful swell. The wind is cross-off and clean. But, and this is a big but, this is way overhead and way too much for Oyster Bay. This is expert-only territory, and even then, it’s borderline too big. The sandbar won’t hold shape at that size. If you’re an absolute charger, maybe, but I’d be watching from the beach.

Tuesday, August 25: The swell drops to a more manageable 6 ft early with a clean cross-off breeze. The energy is down to 1208, but it’s clean and much more doable. This is the best call for experienced surfers in the near term. It’s still inconsistent, but the wind is right and the surf is clean. The morning window is the pick.

Wednesday, August 26: This morning is another gem – 5 ft but with a 18-second period, which is a very long period groundswell. Energy is at 2676, which is decent. The wind is offshore and light, making it glassy. This could be some nice, clean, lined-up sets. The long period might make it a bit straight at a beach break like this, but it’s worth a look. The afternoon falls apart with a strong cross-on.

Thursday, August 27: Back to marginal. A 8 ft SW swell with a light cross-on wind. Clean-ish but not great.

Friday through Sunday, August 28-30: The wind goes onshore and strong again, with 22-28 mph gusts ruining the surf. Swell is all over the place, but it’s all chopped up and messy. Bring the kiteboard if you’re keen.

So, the real jewels in this 16-day stretch are the morning of Tuesday the 25th and the morning of Wednesday the 26th. Both have clean winds and decent swell, with the 26th offering that very long period and glassy conditions. The big swell on the 24th is too much for this spot. Everything else is either blown out or too small. It’s a waiting game, but there’s light at the end of the tunnel.

Rusty out.

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.
