The Lowdown
Tuesday (Sep 8):
We’re starting with a clean, rideable wave. The morning has a light ENE breeze, nearly glassy, with a 1.1m west swell at 12 seconds. It’s not big, but it’s clean, and the water’s sitting at 13°, which is right about average for this time of year. The afternoon turns slightly cross-off with a 1.0m wave, still clean. Nothing to get crazy about, but a good warm-up.
Wednesday (Sep 9):
This is where it starts to pick up. The morning is crystal clear, with a light E breeze, cross-off, and a 1.4m swell from the WSW at 11 seconds. The energy is building (620) and it looks very good. The afternoon gets a touch cross-on with a light WNW wind, but the swell holds at 1.3m. Still, the morning is the pick.
Thursday (Sep 10):
We’ve got a step up in size, but the wind turns onshore and it gets messy. Morning has 25 km/h SW winds with rain, on a 1.9m swell – that’s poor. The afternoon drops the wind to 10 km/h, but it’s still cross-on and the swell pushes to 2.3m, leaving it marginal. Not worth your time unless you’re desperate.
Friday (Sep 11):
Now we’re talking. This is the best on offer. The morning is glassy – dead flat calm – with a solid 3.0m west swell at 18 seconds. This is proper groundswell, and the energy is massive (5260). It’s going to be big and powerful, so this is one for experienced surfers only. Over 2.5m, it’s expert territory. The afternoon stays glassy with a 2.5m swell at 17 seconds – still excellent, but slightly smaller. If you can get out there on Friday morning, you will not regret it. The long period might make it a bit straight at the beach, but this break can handle it.
Saturday (Sep 12):
The swell jumps to a stormy 4.0m with strong 25 km/h WSW onshore winds. This is a full-on mess. Poor conditions, huge and lumpy. Kite surfers might be eyeing this up, but for paddle surfing, stay away.
Sunday (Sep 13):
Swell drops back to 1.5m with a long 16-second period, but the wind is onshore and it’s still messy. Morning is light rain, afternoon has stronger 20 km/h winds. Marginal at best.
Monday (Sep 14):
Another onshore day with 15 km/h WSW winds. Swell is around 1-2.0m, but quality is poor. Not a day for it.
Tuesday (Sep 15):
Signs of life again. Morning has a light NE cross-off breeze, and a clean 1.3m west swell at 14 seconds. It looks very good for the size. The afternoon gets a bit crossed up, but the morning session is worth a paddle.
Wednesday (Sep 16):
Swell builds, but so does the wind. Morning is 20 km/h SW cross-on with a 2.1m swell – poor. The afternoon turns to 35 km/h onshore with a 3.5m swell. Unless you’re on a tow-in, this is a no-go.
Thursday (Sep 17):
This is the other standout, but it’s a problem. The morning is clear with a light ESE cross-off wind and a 4.5m west swell. That’s a huge amount of energy (4719), but it’s way too big for this spot. The forecast even says so. Afternoon has a 3.5m swell with onshore wind. This is purely for the top-tier experts, and even then, it’s a risk. The conditions are clean, but the size is the limiting factor.
Friday (Sep 18) to Sunday (Sep 20):
We’re back to a more manageable size, but the wind turns onshore again. Friday and Saturday are onshore with 1.7m to 2.2m swells – marginal to poor. Sunday morning finally turns glassy again with a 2.5m west swell. That’s a good one for experienced surfers, clean and with decent power. The afternoon gets a light cross-on breeze.
Monday (Sep 21) and Tuesday (Sep 22):
Monday morning is looking clean with a light NE offshore breeze and a 1.5m swell. Nice little runner. The afternoon turns to 25 km/h onshore, so get it early. Tuesday is similar: clear with an ESE cross-off and a 2.2m swell, that’s a solid, clean option before the wind goes west in the arvo.
Wednesday (Sep 23):
The forecast ends with a glassy morning, a light E breeze and a 1.9m swell from the WSW at 16 seconds. Very clean, good energy, and a nice way to wrap things up. The afternoon gets a cross-on breeze, so again, morning is the call.
So, overall, the standout is undoubtedly Friday the 11th – big, glassy, and powerful. The second pick would be Sunday the 20th or Tuesday the 22nd, both offering clean, solid waves for those with a bit of experience. The long-range stuff looks promising, but we all know that can change. Keep an eye on it.

Information about the Cobden Breakwater Surf forecast
The above surf forecast table for Cobden Breakwater provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cobden Breakwater can be found by selecting the local surf guide option on the grey menu. Our Cobden Breakwater 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 (Cobden Breakwater) 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 Cobden Breakwater 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.
