The Lowdown
G’day, Rusty here. Looks like we’ve got a bit of a slow start, but this next week and a half has some real potential for the Cobden Breakwater.
We’re kicking off Tuesday the 21st of July. The first few days are small but clean. Tuesday afternoon brings a 3ft WSW swell with a 12-second period, and it’s glassy. The combined swell energy is weak (305), so it’s not a standout, but it’s a nice little session to get the arms moving. The water temperature is 55°, which is spot on average for this time of year.
Wednesday the 22nd stays in that 3ft to 4ft range, with clean conditions thanks to light cross-off winds. Nothing to write home about, but it’s surfable.
Now, Thursday the 23rd morning is where things start to get interesting. We’ve got a 5ft WSW swell, 13-second period, and offshore wind from the NE at 6 mph. Clean. The combined energy jumps to 700 (moderate). That’s a solid, fun morning.
Friday the 24th morning sees the swell bump up to 6ft from the NW, but the period drops to 8 seconds – short period, so it’ll be a bit softer. Wind is cross-off from the NNE at 12 mph, and the energy is 946 (moderate). The afternoon gets bigger at 7ft, but the wind picks up to 12 mph. It’s still clean, but the quality is marginal due to the short period and size.
Saturday the 25th is a write-off. The morning is a disaster with 15ft of W swell and 19 mph onshore wind. That’s a big, blown-out mess. The energy is 5011 (strong), but it’s unsurfable for anyone. The afternoon drops to 8ft but the wind is still onshore and the period is 15 seconds – too big and messy for this break.
The standout window starts Sunday the 26th. Sunday morning delivers a 7ft W swell, 14-second period, and light cross-off wind from the ESE at 9 mph. Clean. The combined energy is 1723 (strong). This is excellent surf for experienced surfers – solid, powerful, and well-shaped. Sunday afternoon is even better: 6ft, 13-second period, and the wind drops to 6 mph. Still clean. This is the best on offer.
Monday the 27th morning is still very good with 5ft and clean conditions, but the energy drops to 617. The afternoon turns marginal as the wind swings onshore.
We then have a few quiet days, but Thursday the 30th morning is a standout again. A 7ft W swell, 11-second period, and light cross-off wind. Clean. The energy is 1686 (strong). Thursday afternoon is glassy with a 8ft, 15-second swell – that’s a big, long-period groundswell. It’s excellent for experienced surfers, but the long period (15 seconds) means it might break a bit straight here at the breakwater; still, with glassy conditions and 2827 energy, it’s a serious session.
Friday the 31st continues the run with 7ft to 7ft W swell, 14-second period, and glassy or light cross-off conditions. Energy is strong (1719 and 1433). Another excellent stretch.
Saturday the 1st of August is still good but smaller, with 6ft in the morning and 4ft in the afternoon, both clean.
Watch out for Sunday the 2nd of August. The swell is predicted to be 13ft to 15ft – way too big for this break. That’s expert-only, and even then, it’s likely too much. The energy is 4000 to 4075 (very strong). The wind is light, but the size is the problem.
Monday the 3rd of August settles back into a good range: 8ft to 7ft, 13-second period, glassy or light cross-off. Excellent conditions for experienced surfers.
The final few days (Tuesday the 4th to Wednesday the 5th) taper off. Wednesday the 5th morning is poor with onshore wind and a tiny 2ft swell, but the afternoon brings a 2ft, 17-second period swell with clean conditions – a very long period, so it’ll be weak but maybe a fun novelty.
The clear standout is Sunday the 26th and Monday the 27th for the best combination of size, power, and clean conditions. Also, Thursday the 30th through Friday the 31st are top-tier for experienced surfers. The break can get crowded, so expect company during the good windows.
Rusty.

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.
