The Lowdown
Right, let’s have a look at what’s coming down the track for Oyster Bay. This is a sandbar break that’s exposed to the swell, but it’s inconsistent, which means it can be a bit of a waiting game here. The water temp is sitting at 64°, which is pretty normal for this time of year, so no need to worry about a spring suit or a shorty just yet.
The next few days are going to be a bit of a mixed bag. We’ve got a big pulse of energy coming in from the SSW on Sunday the 6th, with the swell pushing up to 12ft carrying a long 18-second period, and the combined energy is massive at 7412. That’s a lot of water moving around, and it’s going to be too big for most, only for the experts. The wind is a cross-off from the east, but at 22 mph it’s a fresh breeze, so it won’t be glassy, but it’ll keep the faces clean. Sunday morning is a bit more manageable at 7ft, but still a solid 20-second period, and 19 mph cross-off wind. The energy is still huge at 4043. This is the standout of the window, but only if you’re experienced and looking for a serious challenge.
Moving into Monday the 7th, the swell drops a touch to 8ft in the morning, but the period is still a solid 14 seconds, and the wind is still a fresh cross-off. The energy is still strong at 2894, but the quality drops off from the Sunday peak. By Tuesday the 8th, things settle right down. Morning sees 4ft at 13 seconds from the SW, with only a slight breeze, and the energy is down to 1009. The conditions are described as excellent for experienced surfers, but the swell is a bit small. That’s probably the most user-friendly session of the first week, but it’s not a standout.
From Wednesday the 9th, the wind swings around to the west and southwest, bringing in cross-onshore and onshore conditions, and the swell drops to under 3ft. The energy is weak (446), and the forecast is poor. This kicks off a long stretch of underwhelming surf. The wind stays messy, often fresh or strong, right through until the 14th, with only a few marginal moments. The swell sticks around 6ft to 8ft, but the wind is rarely your friend. Thursday the 10th has a 6ft swell from the SW with a 13-second period and a light onshore wind, but the energy is moderate at 1156. It’s not worth the paddle.
The next real glimmer comes on Sunday the 13th, but it’s a write-off: near gale force cross-onshore winds at 31-37 mph blow the place apart. Monday the 14th is a bit better wind-wise, but still cross-onshore and choppy.
Then, on Tuesday the 15th, we get a brief moment of magic. Morning conditions are glassy with a 5ft south-west swell at 11 seconds, and the energy is moderate at 1073. The wind is virtually nothing from the WNW. That’s the cleanest the bay will look in the whole 16-day window, and it’s a good option for experienced surfers who want a clean wave without the hassle of huge size. The afternoon gets messy again with an 8ft swell and moderate cross-onshore wind.
After that, from the 16th right through to the 21st, it’s pretty grim. The swell stays up, between 5ft and 10ft, but the wind is almost always cross-onshore, often fresh to strong, and the energy is moderate to strong. The period is short to moderate, with a lot of 8-13 second stuff. The conditions are consistently poor, with only a few marginal slots. The last week is a write-off, with a few weak pulses from the east on the 20th and 21st, but the wind is still onshore. It’s not going to be worth the drive.
So, overall, the best on offer is the Sunday the 6th for the big, powerful groundswell for experts only, and the Tuesday the 15th morning for a clean, glassy session on a smaller, more manageable wave. The rest of the window is a struggle with the wind. This break is inconsistent, so this kind of blank run isn’t unusual, but it tends not to stay poor for long.

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.
