The Lowdown
G’day, it’s Rusty here.
We've got a 16-day window ahead, and honestly, it's a bit of a mixed bag to kick things off. The first couple of days are pretty average, but the second week has some real potential if you’re patient and pick your moments. The first proper call is for Friday the 21st, but it’s nothing to write home about.
We start with a bit of a flat spell. Friday the 21st has a touch of swell at `6.9ft` from the southwest, but a cross-shore wind and a short period of `11 seconds` are making things messy. The combined energy is moderate at `1008`, but the water is a bit colder than normal for this time of year at `56.7°F`, which is notable. The break is Jacobs Bay, and with the conditions as they are, it’s a marginal call at best.
Saturday the 22nd is a bit of a drop-off. Morning sees the swell drop to `4.3ft` with a cross-on breeze, and the afternoon gets even smaller. Not worth the paddle. Sunday the 23rd brings a bit more life with `6.9ft` of WSW swell and a clean cross-off wind in the morning, but the energy is moderate at `1670`. It’s surfable, but still nothing special. Monday is similar, with a cleaner morning at `5.6ft`, but the afternoon gets blown out with a fresh cross-shore.
The first real standout is Tuesday the 25th of August. There’s a solid `7.2ft` of SW groundswell pushing through with a long period of `14 seconds`. The combined energy is strong at `2318`. The morning session has a cross-off wind which will keep it reasonably clean. This is a good one for experienced surfers looking for a proper wave.
Now, look out for Wednesday the 26th of August. This is your pick of the first week. The morning is glassy with a light, offshore SSE airflow. Swell is a clean `4.9ft` from the WSW, and the long period of `13 seconds` gives it real push. The energy is `1196`. Conditions are set up to be absolutely perfect. This is one of those mornings where you’ll want to be in the water early. Jacobs Bay will be working nicely.
Thursday the 27th is a bit of a letdown after that, with a smaller `3.3ft` swell. But don't sleep on Friday the 28th. Another great morning is on the cards with a clean `4.3ft` of long-period WSW swell at `14 seconds` and light offshore winds. It’s a smaller day, but the quality will be there.
Saturday the 29th is a write-off. Strong onshore winds and choppy conditions mean you can leave the board in the car. Then we get to the big one.
Sunday the 30th of August. This is a big water day. The swell jumps to a powerful `13.1ft` from the WSW with a `12 second` period. Combined energy is a massive `4232`. The wind is cross-off and the tide is favorable, but take it from me, this is far too big for Jacobs Bay. This is one for the experts only, and even then, it might be more of a spectacle than a session. This is warning-level size.
Monday the 31st drops back down to a more manageable `5.6ft`. Then, the first of September delivers another standout. Tuesday morning, the 1st, has a clean `6.2ft` of SW groundswell, with a long period of `14 seconds` and light offshore ENE winds. Excellent conditions for experienced surfers. This is a quality mid-week option.
The rest of that week stays consistent but gets a little more challenging. Wednesday the 2nd and Thursday the 3rd have solid swell in the `6.6ft` to `7.2ft` range, but the winds are more onshore and cross-shore. You’ll have to work for it. The last true standout is Thursday the 10th of September. Morning has a clean `5.9ft` of south swell with light offshore winds. It's a long way out, so it’s promising but not a lock.
After that, the period fades out with some smaller, shorter-period swell and less favorable winds. So, mark your calendar for Wednesday the 26th, and keep an eye on the 1st and the 10th of September. There are waves to be had, just pick your windows.

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.
