The Lowdown
Alright, folks, Rusty here. Let's have a look at what Oyster Bay has in store for us over the next couple of weeks.
This is a bit of a tricky stretch. The first few days are not really worth paddling out for, but there are a couple of windows further down the line that should get the blood pumping, especially for those of us who have earned our stripes.
Oyster Bay is an exposed sandbar, and the swell is forecast to be mainly from the SW. It’s an inconsistent set-up, so when it does come alive, you’ve got to be ready to move. The water temperature is currently 62°, which is a bit colder than normal for this time of year—you’ll feel that 3° chill, so a good wetsuit is a must.
Let's get into it. The first real action kicks off on the morning of Monday the 14th. We’ve got a solid 8ft of swell coming in from the ESE with a short, punchy 10-second period. The combined wave energy is strong (1711), and with a light NE offshore breeze, it’s going to be clean. This is excellent surf, but at that size, it’s really for experienced surfers only—this isn't the day for the groms. Crowds are possible here.
Tuesday morning the 15th offers another good look. A clean 5ft wave from the E, with a period of 11 seconds (1074). The wind is light and variable from the NW, keeping the surface glassy. This is a great option for the intermediate crew, as it's a more manageable size, but you’ll still get plenty of push.
Now, we hit a rough patch. The wind turns onshore and starts howling from Wednesday the 16th right through to the end of the following week, making things messy and blown out. Combined energy spikes over 5800 on Wednesday afternoon, but with strong onshore winds, it's just a washing machine. That run of poor conditions lasts for over a week.
The light at the end of the tunnel? The morning of Saturday the 26th of September. The swell drops back to a clean 6ft from the SW with a 12-second period (1152). The wind looks like it will be light and offshore from the NE again, which is a major positive. It’s in the "excellent" zone for experienced surfers, but the size is a touch more manageable than the big Monday swell. Keep an eye on this one, though—it's a long way out, so the forecast might shift.
To be honest, the pick of the whole window is that Monday the 14th. The combination of a solid, clean swell and offshore wind from a good direction makes it the standout, even with the crowds you might find there.
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.
