The Lowdown
Alright, Rusty here with the long-range look at Jacobs Bay. We’ve got a solid 16-day window to chew through, but it’s a real mixed bag. The first few days are a bust for paddle surfing, but there are some absolute gems hidden in there for the patient surfer.
The water is sitting at 54°F right now, which is a massive 6°F colder than usual for this time of year. That’s very unusual, so you’ll want a thick wetsuit and maybe some booties if you’re heading out.
The first real standout we’re looking at is Thursday, September 3rd, in the morning. Jacobs Bay is a beginner-friendly break, and this is the sweet spot. We’ve got a clean 6ft swell rolling in from the WSW with a nice 13-second period. The wind is a light cross-offshore from the SSE at only 3 mph, which is going to keep the faces clean. The wave energy is moderate (1306), and it’s just right for experienced surfers to have a blast. Bigger swell than this would be too much for a beginner, but this is prime.
The absolute standout of the whole forecast, though, is Sunday morning, September 6th. Glassy conditions. The wind is from the NNW at 3 mph, and it’s described as glass. That’s a massive positive. You’re looking at a long-period groundswell of 7ft from the SW with a very long 18-second period. That’s a lot of energy (2946) and it’s going to produce some beautiful, well-shaped lines. The long period means it’ll be a bit more walled up, which is perfect for a point or reef, but at Jacobs Bay, keep an eye on the sets. For a surfer who knows what they’re doing, this is the session to clear your calendar for.
After that, the conditions get a bit messy with cross-shore winds and less consistent energy. There’s a small window on Tuesday morning, September 8th, with a clean 4ft swell from the SSW and light cross-offshore wind, but it’s a drop in size compared to the Sunday peak.
The second week is a bit of a write-off for quality surf. There’s a lot of wind and bigger, unruly swell. The setup on Saturday, September 12th, into Sunday, September 13th, sees a massive spike in energy (3538 and 4518), but the swell is too big for this break, and the winds are strong and cross. It’s a real battle out there and frankly, looks more interesting for kite surfing than paddle surfing. The same goes for Monday the 14th and Wednesday the 16th – plenty of swell, but it’s a mess with strong winds and poor conditions.
So, to sum it up: the first week has the good stuff. Lock in the morning of the 3rd for a clean, fun session, and the morning of the 6th for what could be the wave of the period. The rest is a waiting game.
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.
