The Lowdown
Gather round, surfers. It’s Rusty here. Let’s talk about what’s cookin’ over at Oyster Bay.
Right out the gate, the news is a bit of a heartbreaker. The next week and a half are a mixed bag, and honestly, there’s not a single day I’d call a must-surf. We’ve got a lot of swell, way too much of it, but the wind and the sheer size are going to keep things tricky. This spot only really wakes up with a solid SE groundswell, but the forecast is feeding it a lot of SW energy. The water temp is feelin’ about average for late August, so no wetsuit drama.
The first few days – Sunday and Monday the 23rd and 24th – are just meh. We’re looking at around 6 ft to 7 ft of SW windswell with a period around 11 seconds, but the wind is either cross-on or onshore, making it choppy and messy. The combined wave energy is a moderate 1256 to 1583, but it’s not doing anything clean. No reason to paddle out just yet.
Tuesday the 25th is where it gets interesting but dangerous. The swell jumps to 10 ft with a longer 14-second period. That’s a groundswell with some serious grunt – the combined energy hits 3249 – but 10 ft is too big for this break. The wind is light cross-on, so the face might have a moment, but you’d want to be an absolute expert, and even then, it’s sketchy. This pattern repeats Wednesday the 26th: a powerful 10 ft swell from the S with a very long 16-second period, even bigger energy at 4010 to 4430, but the wind is a stiff 22-25 mph cross-offshore. It’ll look clean from the beach, but the combination of big, long-period groundswell and strong side-offshore wind makes it a beast of a paddle out. Not for the faint of heart.
Thursday the 27th and Friday the 28th see the swell drop back to a more manageable 4 ft to 7 ft, and the wind goes cross-off. It’s cleaner, but the combined energy has dropped into the three-digit range (1073 on Friday morning). Friday morning might have a few nice ones for experienced surfers, but the inconsistency of this break is a barrier.
Then we hit a dead zone. From Saturday the 29th right through Monday the 31st, it’s all poor surf conditions. Swells are tiny, under 4 ft, and the wind is either onshore or a stiff cross-onshore. The energy readings are pathetic – 118 to 276. Don’t bother.
Now, if you’re patient, there’s a glimmer in the long range. Tuesday, September 1st, a big 10 ft SW swell rolls in with a 13-second period and very light, cross-on winds. The combined energy is a strong 2744. This is a true stand-out for expert-level surfers only. Too big for beginners for sure. The caveat is it’s a week away, so the call is less certain, and the break is set up for a SE swell, not SW, so the shape might be a bit walled.
From Wednesday the 2nd through to Monday the 7th, we get a bunch more giant swells, often over 10 ft up to 15 ft, with combined energy readings in the thousands and even hitting 7077 on the 3rd. The wind is sometimes clean, sometimes not, but the size is just relentless. If you’re a big-wave charger, the mornings of Wednesday the 3rd or Saturday the 5th with clean cross-off winds and a 10 ft to 12 ft show could be worth a look. But for the rest of us, this stretch is a write-off due to size. The break is so inconsistent that a long run of poor surf is honestly pretty normal here.
If you’re looking at the setup with all that wind and swell, honestly, the conditions look more set for kite surfing than paddle surfing a lot of this period.
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.
