Updates in hr min s Forecast update imminent
G’day, Rusty here. We’ve got a solid run of swell ahead for J-Bay over the next couple of weeks, but it’s gonna take a bit of patience and reading the winds to find the real gems. The first few days are a little messy, so don’t rush out there on Monday.
Tuesday morning, 7 July, sees 7ft SW swell (1434 energy) with a light cross-offshore breeze. It’s clean but still a bit rough around the edges – a decent warm-up for the better stuff coming. Tuesday afternoon improves with the same 7ft SW swell and a light cross-off, still clean. The water’s sitting at 64°, which is a bit colder than normal for this time of year, so don’t forget the steamer.
The real standout comes through on Friday morning, 10 July. That’s the one. Glassy, light offshores from the west, and a solid 12ft SSW groundswell with a 13-second period pumping in at 4404 energy. This is big, powerful, and lined up – expert territory only. The long-period swell will really suit J-Bay’s point and reef setup, offering deep, barrel-hunting walls with long sets in between. Crowds can pop up here sometimes, but for a swell like this, expect a few chargers out.
After that, the weekend takes a hit. Saturday and Sunday, 11-12 July, see deteriorating conditions with onshore winds and dropping quality. Big lumpy seas on Sunday with 13ft SE swell – that’s a kite day, not a paddle day.
Monday morning, 13 July, gives us a reprieve: 8ft SE swell, clean with a gentle offshore from the WNW (1039 energy). It’s more manageable for intermediates and still clean.
Another absolute standout lands on Sunday, 19 July. That morning, expect a mammoth 15ft SW swell at 5725 energy, 12-second period, with a clean cross-off breeze. This is exceptional, but only for experts. Walls will be thick and heavy. The following Monday, 20 July, goes glassy again early with a 10ft SW swell – excellent for experienced surfers and likely a quieter crowd.
Beyond that, Tuesday and Wednesday of the third week look promising but less certain, with solid SW swell still in the mix but stronger winds blowing.
In short, lock in Friday the 10th and Sunday the 19th as the standouts. Both demand experience, but they’ll deliver.
Rusty.

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.
