Alright, Rusty here. Let’s talk about what’s coming.
We’ve got a solid run of surf lining up for J-Bay (South Africa), starting this Friday afternoon and stretching out over the next couple of weeks. The water’s running at 64.0°, which is a bit colder than normal for the season – you’ll feel it.
The real standout, and the one that’s got me stoked, is Friday afternoon, July 10th. A strong 11.5 ft SSW groundswell with a long 13-second period. The energy reading is a massive 3600 – that’s proper power. And the wind? Glassy. That’s as clean as it gets for this exposed beach-and-reef break. This is for experienced surfers only – over 8.2 ft is expert territory. It’s consistent, and crowds can pop up sometimes, but for that kind of session, it’s worth the company.
Saturday and Sunday look a bit choppy with onshore winds, so those are best avoided.
Next one to circle is Monday morning, July 13th. Glassy again, with a 6.6 ft easterly swell. Shorter period (8 seconds), so less grunt, but clean and much more manageable for intermediates.
Then Thursday, July 16th is another beauty. A 9.8 ft SW groundswell (14-second period) with clean conditions all day. That’s 3743 energy in the morning – serious push. Experts only again.
After that, a few choppy days until Sunday afternoon, July 19th – that evening shapes up nicely. 6.2 ft SSE swell, glassy, and clean. A fun one for the crew.
And finally, Thursday, July 23rd morning looks like a massive spike – 11.5 ft SW swell, 14-second period, with a jaw-dropping 7700 energy reading. The wind is just a slight cross-on, not a dealbreaker. That’s a morning for charging if you’ve got the nerve.
So, for the top picks: Friday July 10th afternoon and Thursday July 16th – both big, clean, glassy groundswell. Experts, get out there. For everyone else, Monday July 13th and Sunday July 19th are your cleaner, smaller windows.

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.
