The Lowdown
Alright, mates, Rusty here. Let’s break it down.
We’re starting off a bit slow, but the first real action is Saturday morning, August 1st, at Jacobs Bay. The water’s at 57°, which is a bit colder than usual—grab the wetsuit. Swell is a clean 5 ft from the SW, with a 14-second period—that’s a nice long-period groundswell with solid energy (731). The wind is a light cross-off from the NE, so it’ll be smooth as glass. Expect very good surf. Saturday afternoon stays glassy, too, with a 4 ft SW swell and a 5 km/h glassy wind from the SW—perfect for a lazy session.
Sunday morning, the 2nd, is a bit messy with a cross-on breeze, but the swell holds at 4 ft SW. Then Monday morning, the 3rd, is another gem: glassy wind from the ENE, 5 ft SW swell at 13 seconds, and energy jumping to 949—moderate but clean. Great for beginners and intermediates.
Tuesday the 4th and Wednesday the 5th get a bit rough with onshore winds and chop. Wednesday afternoon sees a jump to 8 ft SW, but it’s choppy. From Thursday the 6th, the swell really kicks in: 12 ft on Thursday, 10 ft on Friday, and a massive 15 ft on Saturday the 8th—energy over 8000. That’s big, powerful stuff, only for the experts. The wind is cross to cross-off, so it’ll be clean on the sets, but the size is too much for anyone but the brave. Kite surfers might have a field day.
The week of the 10th to the 13th keeps a solid SW swell in the 7 ft to 8 ft range, with cross-off winds and some very long-period waves (up to 21 seconds on Tuesday afternoon). That long-period groundswell is best for reefs and points, not beach breaks. The 13th has strong 45 km/h winds, so it’ll be windy and clean.
The final weekend, the 14th and 15th, drops back to 4 ft to 6 ft, with light winds on Saturday morning. Sunday the 16th is a write-off with rain and strong onshore winds.
The real standouts? Saturday morning, August 1st, at Jacobs Bay—clean, glassy, long-period swell. And Monday morning, the 3rd—another glassy session with good energy. Later in the week, it’s for the big dogs only.
Rusty out.

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.
