The Lowdown
Alright, Rusty here. Let’s have a look at the Oyster Bay sandbar over the next couple of weeks.
Right off the bat, there is a window of surf on the very first day, Tuesday the 1st. The bay is picking up a solid 8ft SSW groundswell with a 12-second period, firing 1534 units of energy. The water is sitting at 62°, which is a solid 4° colder than what we usually get this time of year, so your wetsuit will be feeling that chill. The saving grace is a glassy, offshore wind first thing in the morning. For an exposed sandbar that’s usually inconsistent, this is a real treat. Sets will be a bit walled-off due to the long period on a beach break, but for experienced surfers, that window from dawn to mid-morning on Tuesday is the standout of the whole run. Keep in mind it’s a rare day for this spot, and crowds can pop up when it’s good.
Tuesday afternoon sees a shift to a light cross-onshore that starts putting ripples on the face, and the swell bumps up to 8ft but loses a bit of quality. Wednesday the 2nd is big – 10ft SSW swell with 13-second periods and energy cranking over 3200, but it’s just too much size for this sandbar. Wind is cross-onshore both morning and afternoon, and the break won’t hold it. That might look better for a kite than a paddle.
Thursday and Friday are write-offs. The wind is up around 15-22 mph from the SSE and ESE, choppy, lumpy, and the swell period drops to 8-9 seconds. Not worth paddling out.
Saturday the 5th sees a drop in size to 5ft SSW, period at 11 seconds, and the energy drops to 664. The morning has clean conditions with a cross-offshore breeze from the east, but it’s marginal – a small, weak day with low energy.
Sunday the 6th is an absolute monster setup. The swell jumps to 8ft from the SSW, but the morning period is a *very* long 21 seconds, generating 6344 energy. That’s a groundswell with incredible power but it will run straight down the beach. By afternoon, it’s 16ft from the S, energy hits 17846, and it’s way beyond what a sandbar can handle. Only for extreme experts, and even then, the long period will make it close out. Wind stays cross-offshore and clean, so it’s pretty to look at.
Monday the 7th still has clean, cross-offshore wind and a dropping swell – 8ft in the morning, 6ft in the afternoon – but it’s still a lot of energy and the scores suggest it’s only marginal for the break.
We hit a dismal stretch from Tuesday the 8th through to Wednesday the 16th. A few clean mornings here and there, like the morning of Friday the 11th with a 6ft SSW swell and clean offshore wind from the north, but the overall energy is moderate and the break is inconsistent. Most days are choppy, onshore, or just too small (down to 2-4ft with weak energy under 400). A few afternoon sessions on the 14th and 15th have 8ft SE swell and clean conditions, but the swell direction is wrong for Oyster Bay and the period is short at 8 seconds.
Overall, there’s a gap of about 10 days from the 5th onward where there’s nothing consistent enough to recommend. The run ends with a lot of onshore wind and messy surf. The real standout is Tuesday the 1st morning – that’s your best bet, and it’s a rare one for this sandbar.
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.
