The Lowdown

Alright, Rusty here. Let’s talk about what’s on offer at Cobden Breakwater over the coming weeks.

The good news is there’s surf nearly all the way through, though the first few days are rough. Monday the 3rd of August is a write-off with strong onshore wind and rain washing out the shape. Tuesday the 4th morning stays a bit messy with the cross-off wind, but the afternoon cleans up – light breeze, clear skies, and a 6ft swell from the west with 10-second period. That’s the first real window.

Wednesday the 5th is the early standout. The morning has a light cross-off breeze with a 3ft WSW groundswell, period of 13 seconds, and the afternoon goes glassy. The combined energy is 397 (moderate) in the morning, dropping to 249 by the afternoon. It’s not big, but those long-period waves will wrap in clean. Water temperature sits at 54°, about average for the time of year.

The next real highlight is Friday the 7th afternoon. A 8ft swell from the NW, period of 10 seconds, and an almost glassy cross-off wind. Combined energy hits 1259 (strong). This is intermediate territory – a bit much for beginners, but good for anyone with some experience. Breaks are fairly consistent here, and crowds are rare, so you should get plenty of waves.

Sunday the 9th morning is another strong option. A 6ft W groundswell with 13-second period, light offshore wind, combined energy of 1043 (strong). Conditions will be clean and lined up. The size is manageable for intermediates, and it’s just a good, honest session.

Looking into the second week, Thursday the 13th morning has some juice: 6ft from the west, 17-second period, combined energy of 2764 (very strong). That’s a powerful swell and it’s going to be solid. For experienced surfers only at that size. The cross-off wind keeps it clean. It’s a promising call but further out, so keep an eye on it.

Saturday the 15th is a classic. Both morning and afternoon are glassy, with a 5ft W swell (15-second period) in the morning and 4ft WSW in the afternoon. Combined energy is 1714 and 1434 respectively. This is the best combo of clean, manageable size, and quality groundswell. A real standout for the whole outlook.

Sunday the 16th afternoon sees the biggest swell of the run: 10ft from the west, 12-second period, with a cross-off breeze and combined energy of 2989 (very strong). Experts only here – this is raw and powerful.

After that, things taper off. Monday the 17th morning is messy, but the afternoon goes dead glassy with a small 3ft WSW swell wrapping in. Tuesday the 18th gets blown out by onshore wind.

Overall, the standout days are Wednesday 5th afternoon for a glassy, long-period session, and Saturday 15th for the combination of clean conditions and solid groundswell. If you’re experienced, Thursday 13th morning and Sunday 16th afternoon are worth marking in the calendar, but check closer to the date.

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.
