Table - best surf conditions forecast for Jacobs Bay over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Jacobs Bay over the next couple of weeks.
Right off the bat, we’ve got a slow start. Monday the 13th and Tuesday the 14th offer some tiny, clean waves, but they’re pretty weak, so don’t get your hopes up. The real story starts to build toward the middle of the week.
The standout window is definitely Wednesday the 15th. That morning, the bay is going to be absolutely firing. We’re looking at a clean 4.6ft SSW groundswell with a very long 16-second period, pumping in with strong energy (1257). The wind is glassy out of the ESE, so the surface will be perfect. The wave comment says it’s excellent for experienced surfers, and that’s the truth – that long period swell will be lining up beautifully. This is the pick of the whole forecast.
We get a bit of a lull through the rest of that week, with smaller, choppier conditions, but then Sunday the 19th morning shapes up as another good one. A solid 6.9ft WSW groundswell (1260 energy) with a decent 12-second period, coming in with a clean cross-offshore breeze. That’s worth a paddle.
After that, things get a bit wild. Monday the 21st sees a massive 9.8ft SW groundswell (5159 energy) with a 16-second period, but it’s flagged as too big for the break. The same goes for Thursday the 23rd morning with a 16.4ft SW swell (8026 energy) – that’s proper big-wave territory, only for the absolute experts if they can handle it. The afternoon of the 23rd does clean up and drop to 8.2ft with glassy conditions, which is a solid shout for the brave.
The final few days are a mix of huge, lumpy conditions and days where the swell is way too big, with strong winds making it a messy affair. For the most part, after the 21st, it’s either giant or blown out, so keep your eyes on the earlier windows.
Stay stoked.

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.
