The Lowdown
Alright, surfers, Rusty here. Let's get into what's on the table for the next couple of weeks.
Right now, the start of the period is a bit of a write-off. We've got a couple of days of small, messy, and cross-onshore conditions at J-Bay that aren't worth your time. The waves are there, but the quality is just not there. After Monday, the outlook starts to turn around.
The first real standout comes on Tuesday, August 4th. J-Bay is looking pretty good. The morning session is where it's at with a clean 5ft swell from the southwest, a 12-second period, and a light cross-offshore breeze from the north. The water is a touch cooler than usual at 63°, so a thicker suit might be the call. The combined swell energy is a solid moderate 1183, so there's some push.
Things get serious on Thursday, August 6th. The morning is a cracker for experienced surfers. The swell hits 12ft from the southwest, with a period of 13 seconds. The wind is light and cross-offshore, making for clean conditions. The energy is strong at 4173, so this is a powerful day. Friday gets messy with onshore winds, but Saturday, August 8th, is a great follow-up. The morning has a clean 8ft SW swell, light cross-offshore winds, and excellent conditions.
We have a few wild days around the 9th and 10th with strong winds and a lot of rain. On the 11th, the swell gets huge, hitting 23ft on Tuesday afternoon, but it's too big for J-Bay and the wind is messy. This is more of a kite-surfing setup than a paddle-surfing one.
The second week offers a couple of gems. The best of the bunch is Saturday, August 15th. The morning is glassy, with a 4ft, 15-second groundswell from the southwest. The energy is moderate at 1110, and it’s a perfect option for a clean, cruisy session. Then, Sunday, August 16th, is also fantastic. The morning is glassy again with a 6ft, 14-second SW swell. Both of these are excellent, clean windows for a good surf.
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.
