Alright, let's talk waves. Rusty here with the J-Bay breakdown.
First call is Tuesday afternoon, July 7th. We've got a clean 2.2m SW swell with some energy behind it (combined energy of 1438). The water's sitting at 18°, a touch colder than usual for July.
The big highlight is Thursday, July 9th and Friday, July 10th. Thursday afternoon brings a 3.0m SSW swell, strong energy at 3594, and cross-offshore winds. Friday morning is the real stand-out though: a solid 12ft SSW swell with a huge 4537 in the energy department and a light W cross-off. This is expert-only, heavy-duty stuff. The period is around 14 seconds, a proper groundswell that will work a treat on the point at J-Bay (beach and reef). The swell is from the SSW, which is spot on for this break. Expect some crowds, as it can get busy.
Monday, July 13th sees a shift to a short period E swell, clean but not the same power. Tuesday, July 14th morning is a nice change of pace: glassy, with a 5ft E swell. The energy is lower at 682, making it a much more manageable session.
It gets a bit messy after that for a few days with strong winds and poor quality.
The second week brings another highlight. Tuesday, July 22nd morning has a solid 7ft SW swell, clean with a NNW cross-off. Good energy at 1018. But the absolute pick is Wednesday, July 22nd afternoon. It's glassy, with a 7ft SW swell and 1084 in the energy department. Light winds, clean lines. That's a serious session to plan for, though it's far out so keep tabs on it.
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.
