The Lowdown

Right, listen up. Rusty here. Let’s have a proper look at what J-Bay has got cooking for us over the next couple of weeks.

We’re in for a bit of a mixed bag, to be honest. The first few days are a write-off, proper messy with cross-onshore winds and lumpy, choppy conditions. The swell is there, but it’s not doing us any favours. Friday the 31st and Saturday the 1st are a firm "stay at home" situation. Then Sunday the 2nd has a bit of size but the wind is still cross-on, making it marginal at best. You’ll be battling ripples.

But then, look at Monday the 3rd. That’s where it starts to get interesting. The morning is glassy, dead flat calm. The swell is a clean 5.6ft from the ESE at 10 seconds. The combined energy is moderate (1149). That’s the kind of session that’s excellent for experienced surfers – clean, no wind, and proper waves rolling in. The water temp is about average for this time of year, so nothing wild there.

The star of the show, however, is shaping up for Thursday the 6th of August. Don’t let the "marginal" label fool you. The morning has a solid 13.1ft SW groundswell with a 13-second period, and the wind is clean cross-off from the WSW. The combined energy is a massive 9334 – that’s strong to very strong wave energy. This is big, powerful, expert-level surf. The afternoon is still excellent, dropping to 8.2ft but still with a clean cross-off breeze. If you’re experienced, that Thursday morning is the standout. It’s going to be a raw, powerful day at the point.

Wednesday the 5th is also worth a look. The morning is glassy again with a 3.6ft, very long-period groundswell from the SW (16 seconds). That’s a classic long-period groundswell that will wrap in beautifully. The energy is moderate (997), but those long gaps between sets make paddling out easier. The afternoon, though, jumps to 9.8ft with a 15-second period – that’s a lot of power, but the wind goes cross-shore, so it won’t be as clean as the morning.

The second week gets a bit more unpredictable. Monday the 10th has clean cross-off winds and a solid 6.6ft swell, but it’s not quite the monster of the 6th. Wednesday the 12th morning has offshore wind and a 9.8ft SSE swell, which is a proper surprise, but the clouds and a bit of chop in the afternoon could mess with it. The weekend of the 15th and 16th looks like a return to smaller, cleaner conditions but with less energy. The crowds at J-Bay can be a thing, especially on the good days, so get in early if you can.

The Pick: Without a doubt, Thursday the 6th of August morning. That 13.1ft SW groundswell with clean cross-off wind is the big one. It’s a day for the experts only. The Tuesday the 4th morning and Monday the 3rd morning are also excellent, but they’re smaller. If you want a glassy, long-period session, Wednesday the 5th morning is your best bet.

Information about the J-Bay Surf forecast

The above surf forecast table for J-Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at J-Bay can be found by selecting the local surf guide option on the grey menu. Our J-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 (J-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 J-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.

J-Bay is 19 km (12 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.
