The Lowdown
Alright, mate, Rusty here. Let’s break it down.
The first real surf window for Oyster Bay doesn’t open until Friday, August 14th. The early part of the week is a write-off with strong onshore winds and junky conditions, so don’t even think about paddling out Monday through Thursday morning. You’ll have to wait, but there’s some clean stuff coming.
Friday, August 14th is the standout. The morning brings a 5ft SSW groundswell with a smooth 16-second period, and the wind is blowing true offshore from the NE at 12 mph. That means clean, well-shaped waves. The combined energy is moderate (1882), so there’s enough push without it being out of control. This is excellent for experienced surfers – the swell direction (SW) lines up perfectly with what Oyster Bay likes, and the conditions will be glassy. Crowds are sometimes an issue here, so expect some company, but with that offshore wind, it’ll be worth the paddle.
Saturday, August 15th morning is also a decent call. Swell drops to 4ft from the SW, period still at 14 seconds, with a light N offshore at 9 mph. Combined energy is lower (801), but the gentle offshore wind will give you clean, fun waves. Not the biggest, but very surfable.
Water temp is 61°F, which is 5°F colder than normal for this time of year – that’s noticeably chilly, so bring a thicker wetsuit and maybe a hood. It’s going to feel cold.
Sunday, August 16th morning has a shorter-period E swell (5ft, 9 seconds) with light winds, but the energy is weak (378). It’s an option if you’re desperate, but nothing special.
Looking ahead, Monday, August 24th and Tuesday, August 25th show a massive jump in swell – 10ft to 12ft from the SW with a long period (14-15 seconds). The combined energy is huge (4294 to 5425), and the winds are clean cross-offshore. But that size is just too much for Oyster Bay. It’s expert-only territory, and even then, it’s pushing the limits. Beginners should stay on the beach. This is promising but less certain this far out – keep an eye on it.
Bottom line: Friday, August 14th morning is your best shot. Get out there while it’s clean.
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.
