The Lowdown
Alright, let’s get into it.
The next couple of weeks are a bit of a mixed bag around Oyster Bay (Oyster Bay). We’ve got some punchy swell early on, but the winds and the size are going to be working against us for a few days. The real windows of opportunity are narrow, and you gotta be picky about when you paddle out. It’s not all doom and gloom though, there are a couple of days that are going to be worth circling on the calendar.
The first session that’s worth your time kicks off on Tuesday the 1st. Tuesday morning is looking glassy with light winds out of the south. Swell is a solid 8ft from the southwest with a 12-second period, and the energy is strong. It’s got that powerful, groundswell feel to it. This is an exposed sandbar, so with that long period, it could be breaking a bit straight, but the clean conditions are going to make it a hell of a lot of fun for the experienced crew. The water temp is about average for this time of year, so no surprises there. This is going to be one of the better windows. The afternoon looks a touch bigger at 8ft, but it’s still clean.
Forget the next couple of days after that. Wednesday the 2nd the swell jumps to 10ft, and that’s just too much grunt for this spot. It’s a pity because the wind is favourable, but the sheer size is going to close it out and make it a mess. Thursday the 3rd sees the wind swing onshore with rain, and it just gets lumpy and poor. Friday the 4th is blown out with strong cross-shore winds, so that’s a write-off too. Saturday the 5th is small and weak, not worth your time. And Sunday the 6th? Big swell, 12ft with an 18-second period, but the wind is howling cross-shore and it’s going to be a complete washing machine. Monday the 7th is still too messy with strong winds.
Now here’s the standout. Tuesday the 8th is the day. Morning has a moderate offshore wind, and the afternoon goes glassy with a gentle offshore breeze. Swell is 7ft from the east with a 10-second period. The energy is moderate, but that offshore wind is going to groom it into clean, lined-up sets. It’s not huge, but it’s got enough push to be fun and the conditions are going to be perfect. This is the pick of the whole forecast. The consistency is listed as inconsistent, so you’ll have to wait for them, but the ones you get will be worth it. Get on it.
The rest of the second week drops off. Wednesday the 9th is much smaller with cleanish cross-offshore winds, but weak at around 4ft. It’s a grovel. The weekend and early next week just get poor again with onshore winds and lumpy surf. Monday the 14th has another pulse of big swell with strong winds, making it poor and messy.
So, to sum it up: you have two main windows. The first is the clean, powerful surf on the morning of the 1st of September, and the absolute standout is the offshore, clean conditions on the 8th of September. That's the one to clear your schedule for. The long-range stuff around the 16th looks promising size-wise, but it’s too far out to call and it’s just too big for this break anyway.

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.
