The Lowdown
Alright folks, Rusty here. Let's talk Jacobs Bay. Just this spot, nothing else.
First thing you're gonna notice is the water, it's sitting at 54°, which is a crazy 6° colder than usual for this time of year. That is very unusual, so you'll want a thick hooded suit. Despite the freeze, there's a short window to get some.
The real standout is Thursday morning, September 3rd. Wind is glassy out of the SW at only 3 mph, and we've got a solid 6ft groundswell from the WSW with a long period of 13 seconds. The wave energy is strong, coming in at (1327). This is producing clean, excellent waves. But 6ft is pushing it for bigger beginners, and that energy means it's got some punch. This is prime for experienced surfers. Crowds are only *sometimes* an issue here, so you might have it good.
Thursday afternoon is a loss – that 37 mph SSE wind is a near-gale, wrecking the 12ft swell.
Friday the 4th stays too big with 10ft to 12ft swell and strong cross-off winds. That's expert-only territory. Saturday the 5th drops a bit, but the wind and tide looks dodgy, even with the swell down to 7ft to 8ft. Not worth it.
Now, Sunday morning, September 6th, is interesting. We've got a 6ft groundswell from the SW with a very long period of 18 seconds, producing strong energy (2587). This kind of long period can make a beach break wall up and close out, but it has long lulls, making the paddle out easier. The wind is a light breeze, glassy. Another one for the experienced crew only.
After that Sunday morning, the quality drops hard. From Sunday afternoon all the way to Wednesday the 16th, it's marginal conditions, poor wind, or just not enough decent swell. That's a solid 12-day gap with no good options.
There's a brief spike on Sunday, September 13th, with swell hitting 10ft to 13ft and clean cross-off winds. The energy is massive (3908), but that's big-wave territory. Only for the hardcore.
Monday the 14th stays big and choppy, then it fades into smaller, messy stuff.
The call: Your best shot is Thursday morning, September 3rd for that glassy, clean 6ft groundswell. If you can't make that, Sunday morning, September 6th is your backup, but it's powerful and peaky. After that, it's a long wait.
Stay warm out there.
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.
