The Lowdown

G’day, it’s 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 morning glass-off spot, but it can get a bit moody when the wind picks up.

The water's sitting at 63°, which is a bit colder than what we’d normally expect for this time of year, so you'll want the warmest rubber you've got. The early part of this run is all about small, clean windows, but the real story is the sequence of bigger swells that starts in the second week. The best of the best is going to be that Wednesday the 16th morning, but it might be too much juice and the conditions are good for a lot of days before that.

Tuesday the 8th looks like a nice way to kick things off. The morning is glassy with a 4ft SW swell at 13 seconds, and the energy is moderate at 998. It’s a bit inconsistent, but when they come through, they’ll be clean. The afternoon sees a cross-off breeze keeping things tidy with 4ft swell at 12 seconds. This is a good start.

Wednesday the 9th is still in the small but clean category. The morning has a light cross-off with 3ft SW, 11 seconds. The afternoon gets a bit more cross, dropping the quality a notch. Still, there are waves.

Thursday the 10th is a write-off. The morning turns cross-onshore and choppy with a moderate breeze and a 4ft SW, 13-second swell, energy is pushing 1039. The afternoon gets bigger, 7ft SW at 15 seconds, and the energy jumps to 2151, but it’s lumpy and cross-onshore. Not worth the paddle.

Now, Friday the 11th is where it starts to get interesting. Morning has a nice cross-off wind and 6ft SW at 13 seconds, with strong energy at 1268. The forecast says 'excellent for experienced surfers,' and I’d agree. It’s pushing the size but still clean. The afternoon sees a fresh cross-off, but it’s a bit messy.

Saturday the 12th has a glassy morning, but it drops to 3ft, so not much push. The afternoon is the standout for the weekend – clean cross-off, 6ft SW at 14 seconds, and 1683 of energy. This will be firing for the better surfers. Sunday the 13th has size, up to 7ft from the SW at 14 seconds, but the wind is fresh and it’s marginal. The wave quality suffers.

We have a bit of a lull from Monday the 14th and Tuesday the 15th, with smaller swells in the 4ft to 4ft range. Monday afternoon is glassy and clean, and Tuesday morning has a light offshore, both are good options for the log or a fun shortboard. But it’s not the main event.

Now, hold onto your board. Wednesday the 16th is the big one. The morning is a 10ft SW swell at a very long 18 seconds. That's a massive amount of energy, 5237! The wind is light and the tide is favorable, but this is way too big for Oyster Bay, and it’s only for the most expert chargers. Unless you’re seriously good, give it a miss. The afternoon is the same story, too big at 10ft.

Thursday the 17th stays well over the top. The morning is a 8ft SW, and the afternoon is a huge 15ft S swell at 10 seconds. This is dangerous, messy stuff. It’s not a surf day.

Friday the 18th remains huge and messy. The morning is 13ft from the SSE, and the afternoon is 10ft from the SE. The W wind on the afternoon will chop it up further. This is a hard no.

The weekend of the 19th and 20th is blown out. Strong cross-onshore winds, big and lumpy. We're looking at 8ft to 12ft with the weather gods angry. I wouldn't even go down to look.

The swells start to back off and the winds shift for the better. The standout here is Monday the 21st morning, with a clean cross-off wind and a 6ft SW swell at 14 seconds, energy at 1916. The break will be showing its best face. The rest of the week is plagued by strong winds, but the swell stays around 4ft to 7ft. It’s the wind that’s the problem, making the afternoon sessions messy. The last few days have strong to near-gale winds, which makes it rocky. There’s still a clean wave on Tuesday morning if you’re keen and the winds are offshore, but it gets hard work.

So all in all, the first few days are your small, clean sessions, but the real gold is Saturday afternoon the 12th and Monday morning the 21st. The 16th is enormous and for experts only. Oyster Bay is inconsistent, so you have to pick your moments, and the crowd is sometimes there, so get out there early. This is Rusty, signing off.

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.
