The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up at Jacobs Bay over the next couple of weeks.
The water’s sitting at 55°, which is a solid 4° colder than what’s normal for this time of year. That’s a noticeable chill, so if you’re heading out, you’ll want a decent wetsuit.
We’ve got a mixed bag coming in. The first few days offer some swell, but the wind is a bit of a bully, making it tricky to find a clean window. Things start to shape up properly from later in the week, and there’s a real standout session on the horizon.
The pick of the lot is likely the glassy morning on Saturday, August 15th. The swell is a consistent 6 ft from the WSW, with a period of 14 seconds, so there’s some decent energy in the water (1346). The wind is dead calm, glassy as a mirror. That’s a morning to paddle out early and just enjoy the smooth lines. Jacobs Bay is a beginner-friendly spot that’s fairly consistent, but with 6 ft swell it’ll be pushing it for the absolute greenhorns. It’s a solid, fun-size wave for the rest of us.
We also have a promising Monday morning on the 17th. The swell bumps up to 8 ft from the WSW, with a period of 13 seconds and heaps of energy (2245). The wind is glassy again. That’s a proper groundswell, and it’s going to be a powerful wave. At 8 ft, this is firmly in the experienced-only zone. But if you’ve got the skills, this could be a ripper before the wind swings onshore later.
Beyond that, things get a bit messy. The following week has some strong southerly winds that chop things up. We do see another clean shot on Saturday the 22nd, with a glassy morning and 5 ft swell from the SW. The energy is moderate (982), and it’s a much more manageable size. That’s a nice, relaxed session for anyone.
The long-range forecast has a couple of potential bright spots, like the mornings of the 23rd and 24th, with clean conditions and solid 6 ft to 8 ft SW groundswell. Plenty of energy there (1572 and 1855). But we’re talking a week and a half out, so keep an eye on the forecast. It’s promising but not locked in.
There’s a decent run of swell here, and a few real gems to get excited about, especially those Saturday and Monday windows. Don’t sleep on that glassy dawn patrol.
Rusty.

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.
