The Lowdown

G’day, Rusty here. Look, I’ve been staring at the charts for Oyster Bay and I gotta be straight with you—this 16-day run is a real mixed bag, and for most of it, you’ll be wrestling with some serious size and wind. The first half of the window is dominated by a big, powerful groundswell that’s just too much for this spot, then things clean up for a few sweet windows if you know where to look. The water’s sitting at 63°, which is a notable 3° colder than average for this time of year, so you’ll want a decent steamer.

The real standout here is Tuesday the 8th of September. The morning session at Oyster Bay is the pick of the whole run. We’ve got a clean 4ft southwest swell with a lovely 13-second period—that’s got proper energy behind it (1070) and the wind is dead calm, glassy as a mirror. This is excellent, lined-up surf for experienced surfers. The afternoon drops a touch to 4ft but stays clean with a light cross-off breeze; still very good waves.

After that, things go south pretty quick. From Wednesday the 9th right through to Sunday the 13th, it’s a frustrating mix of lumpy onshores, lumpy chop, and questionable tides. The swell hangs around but the quality is poor. Monday the 14th is no better—strong cross-onshore winds messing up a 10ft swell.

Then we get another cracker. Tuesday morning the 15th of September is worth setting the alarm for. A clean 8ft southwest groundswell (11-second period, combined energy of 1966) with a gentle offshore breeze from the NE. That’s a solid, powerful wave that’s still manageable for the experienced crew. It’s big enough to be a handful though—over 8ft means experts only. The afternoon stays big at 10ft with a moderate cross-off, but that’s pushing the limit for Oyster Bay.

The rest of the second week is a write-off. From Wednesday the 16th all the way to the end of the window on the 21st, it’s mostly strong cross-onshores, lumpy mess, and poor conditions. There is one glimmer: Sunday morning the 20th of September looks glassy again with a 7ft southwest swell and 14-second period, but it’s a long way out, so keep an eye on the forecasts.

Bottom line: Don’t bother paddling out most days. The best windows are Tuesday the 8th morning (small, clean, glassy) and Tuesday the 15th morning (big, offshore, powerful). If you’re chasing the bigger stuff, the 15th is your day. Otherwise, save your energy.

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.
