The Lowdown
Alright, let’s get into it.
We’ve got a stretch of surf coming up at Jacobs Bay, but honestly, the start of this period is a bit of a write-off for paddle surfing. From Thursday the 6th through the weekend, the swell is just too damn big for this spot. We’re looking at a solid 10ft to 12ft of SW swell, with a strong combined energy reading of (3598) to (4815). That’s a lot of water moving around, way too much for a beginner-friendly break like this. It’s more of a kite-surfing kind of show.
Things start to settle early next week. Monday the 10th the swell drops to 6ft and the energy eases (2088), but it’s still a bit messy and marginal. Not worth getting too excited.
Then, here’s the standout – Tuesday the 11th of August. That morning we get a clean 7ft S swell with a decent 13-second period, and the wind is offshore from the east at 9 mph. It’s setting up some proper clean lines. By the afternoon, it gets even better: glassy conditions, not a breath of wind, and the swell holds at a manageable 6ft. This is the best window. The energy is moderate (1348), but for an experienced surfer, this is going to be absolutely fun. It’s a bit too big for beginners, but for anyone comfortable in overhead surf, this is the session to circle.
Wednesday the 12th also looks promising. A solid 6ft WSW groundswell with a very long 18-second period. The morning is clean with light ENE winds. That long period means the waves will have serious push and shape, but at a beach break like Jacobs Bay, it can get a bit straight and testing. Still, it’s worth a look for the experienced crew.
After that, there’s a bit of a lull through the middle of the month with mixed conditions and smaller, shorter-period swell hanging around 5ft to 6ft. Not much to write home about until Sunday the 16th, when we get another glassy morning with 6ft WSW swell. It’s not massive, but clean, and that’s always a good thing.
Looking further out, the 18th of August sees a bump in size again with 8ft WSW swell, but the wind is cross-onshore and it’s likely going to be a bit of a mess. It’s a potentially powerful swell but not the cleanest setup.
The last real notable window is on Thursday the 21st of August. The morning brings a clean 6ft SW swell with an offshore breeze from the southeast at 9 mph. It’s the kind of session that could end the period on a high note for anyone with a bit of experience.
So, bottom line: Tuesday the 11th is the unquestioned best day. Wednesday the 12th is a good second. Everything else is either too big, too small, or too windy for a proper session at Jacobs Bay. Keep an eye on that Tuesday.

Information about the Jacobs Bay Surf forecast
The above surf forecast table for Jacobs Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jacobs Bay can be found by selecting the local surf guide option on the grey menu. Our Jacobs 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 (Jacobs 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 Jacobs 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.
Jacobs Bay is 8 km (5 miles) from the city of Saldanha. If you plan a holiday in West Coast, look for hotels and other accommodation in Saldanha. Saldanha has rooms for a wide range of budgets as well as car hire and transport links.
