The Lowdown
G'day, it's Rusty here. Let's talk about the surf at Jacobs Bay. We've got a solid run of swell coming through, but it's a mixed bag of conditions, so you'll need to pick your moments carefully. The water is sitting a bit cooler than usual, about 56°, which is a touch colder than the norm for this time of year.
The first real standout for experienced surfers hits on Tuesday, the 11th of August. The morning is looking prime with a clean 7ft SSW groundswell, a period of 13 seconds, and light offshore winds from the east at 9 mph. The combined energy is significant, sitting at 1600 (moderate wave energy). This is a solid, powerful swell that will reel off nicely with that offshore wind. Tuesday afternoon still holds good surf at 6ft SSW, but it's a bit more cross-off, so the morning is your best bet.
Wednesday, the 12th of August, is another cracker for the experienced crew. The morning session delivers a 6ft SW groundswell with a very long period of 18 seconds, and light ENE winds at 6 mph. The energy is up there at 2388 (moderate to strong wave energy). That long period will create some beautifully shaped, powerful lines, especially at a point or reef. The afternoon goes a bit more marginal, but still clean.
Now, there's a few days in the middle of the week that get a bit messy with strong winds, but we get a glassy gem on the morning of Sunday, the 16th of August. The wind is a perfect 3 mph from the southeast, making it glassy, and the swell is a clean 6ft from the WSW at 13 seconds. It's a touch smaller, but with that glassy surface, it's going to be a joy to surf. The energy is 1083 (moderate wave energy).
The biggest surf of the period hits on Monday, the 17th of August, with a 10ft WSW swell, but it's predicted to be too big for this break, so best to avoid. The following week sees a drop in size and quality, with a lot of choppy, wind-affected days. There's a chance of a clean morning on Thursday, the 20th of August, with a 6ft WSW swell and gentle cross-off winds, but the energy is a bit lower.
So, overall, the standout is Tuesday morning, the 11th, for the best combination of size, period, and offshore wind. The glassy morning on Sunday, the 16th, is a close second for pure, clean conditions. The crowds can be around sometimes, so get in early.
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.
