Alright, Rusty here again. Let’s break down Cobden Breakwater in feet and Fahrenheit.
The next couple of weeks look good. Starting this Friday, the 10th of July, we’ve got a long run of groundswell from the WSW. The water temp is a bit cooler than the long-term average for this time of year, so you’ll want a thicker wetsuit.
The standout is Wednesday the 15th of July. That morning, the swell hits 10ft from the W with a 15-second period, and the combined energy is a massive 3339. That’s serious power. Wind is offshore from the NE, so it’s clean and lined up. This is for experienced surfers only – too big for beginners. The afternoon gets cross-shore, so get in early.
Before that, the weekend is solid. Friday the 10th starts with clean 4ft WSW swell, glassy in the afternoon. Saturday the 11th is even better – glassy again, dead calm wind in the afternoon. Sunday the 12th holds clean 4ft waves. Monday the 13th sees a shift to a shorter-period NNW swell, but still clean.
Tuesday the 14th afternoon is a treat – swell swings back to the W, 6ft with a 13-second period, energy at 1315. Light cross-off wind, clean and punchy.
After the big Wednesday, things settle. Thursday the 16th is onshore and messy. Friday the 17th is back to clean, fun 4ft WSW swell. Saturday the 18th sees another NNW pulse, 8ft to 8ft, clean – another good one for the experienced crew.
The second week trails off into smaller, cleaner waves. From the 19th to the 22nd, we’re looking at waist-to-chest high WSW groundswell, often glassy. Crowds are rare. By the 23rd and 24th, it’s small and weak, but the 25th of July shows a little pulse back to 3ft.
Overall, the first week is the real deal. Wednesday the 15th morning is the best – big, clean, and powerful. Saturday the 18th is another standout. The rest of the window has plenty of fun, clean waves for the average surfer.
Rusty.

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.
