The Lowdown
Alright, Rusty here. Let’s have a look at this stretch. The main show is all at Cobden Breakwater. We’ve got a solid run of surf coming through, but it’s a mixed bag of conditions, so you’ve got to pick your moments.
Things kick off on Tuesday the 11th with a clean 3ft southwest swell and a light offshore breeze. It’s not big, but it’s tidy, with moderate wave energy (242). The water’s sitting at 54°, which is pretty much normal for this time of year. That afternoon, the swell drops to 2ft, but with a super long 18-second period—pure groundswell—and only 3 mph of wind. It’s clean, but tiny.
Wednesday the 12th morning is a bit messy with a cross-off wind and a 3ft northwest swell, but the energy jumps (430). The afternoon is a different beast: an 8ft NNW swell with offshore wind and massive energy (1786). That’s expert territory, too big for the average punter, and it’ll be powerful.
Thursday the 13th brings a solid 6ft WNW swell in the morning with light offshore wind and strong energy (800). Conditions are very good. The afternoon stays similar at 5ft with cross-off wind and energy at 841. Both sessions are clean and juicy.
Friday the 14th has a morning 3ft WSW swell with a 15-second period and moderate energy (504). Clean with a cross-off breeze. The afternoon gets a 4ft west swell, but the wind turns onshore, so it’s messy.
Now, the standout of the whole forecast is Saturday the 15th. We’ve got a solid 8ft west swell, a 16-second period, and glassy conditions. The energy is pumping (2935). This is a serious session for experienced surfers only. That morning, it’ll be perfect—clean, powerful, and lined up. The afternoon gets onshore, so don’t sleep in.
Sunday the 16th holds onto the swell at 7ft west with a 15-second period and cross-off winds all day. Energy is still high (1763). Both morning and afternoon are clean and excellent for the experienced crowd.
Monday the 17th sees the swell drop to 5ft from the WSW, period at 14 seconds, and cross-off wind in the morning. Clean with good energy (834). Afternoon turns onshore, so go early.
Tuesday the 18th morning offers a clean 4ft WSW swell with cross-off wind and moderate energy (571). Afternoon gets a light cross-onshore, but it’s still surfable for those who don’t mind a little texture.
Wednesday the 19th morning has a 4ft WSW swell, 16-second period, cross-off breeze, and clean waves. Energy is solid (871). Afternoon goes cross-onshore again.
Thursday the 20th and Friday the 21st deliver clean mornings with 3-4ft WSW swells and light winds. Friday afternoon even goes glassy with no wind at all. These are smaller but clean fun waves.
Saturday the 22nd starts glassy with a small 3ft swell, but the afternoon turns onshore and messy. Sunday the 23rd has a clean 3ft WSW swell in the morning, but the afternoon pops a 8ft west swell with a short 8-second period and onshore wind—not great.
Monday the 24th morning brings an 8ft west swell with clean conditions and strong energy (1548). Tuesday the 25th morning is the biggest of the run: 10ft west swell, clean, and energy at 2155. Both are only for experts, and with short periods (10 seconds), the power will be punchy.
After that, Wednesday the 26th backs right off to a clean 3ft WSW swell.
Overall, Saturday the 15th is the absolute pick of the bunch—big, glassy, and powerful. Tuesday the 25th is a close second for size, but it's a solid week out, so keep an eye on it. The crowds at Cobden Breakwater are listed as rare, so you might have it mostly to yourself.

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.
