The Lowdown

Alright, Rusty here again. Let’s run through the same story in feet and miles.

The opening act is a bit lackluster, but the main event is a Friday that’s pure magic. The wave energy is pumping (5618), with a 10-foot swell out of the west, a 18-second period – that’s a long-period groundswell, packing a serious punch. And the wind? A light offshore breeze, almost glass. The lineup will be clean as a whistle. The afternoon gets even better, going dead calm with zero wind, still a solid 10-foot west swell. This is big stuff, so it’s for the experts only. If you’re up for it, don’t even think about missing it.

So, Tuesday the 8th is a gentle start. You’ve got a clean 4-foot west swell, 12-second period, and light cross-off winds. The energy is moderate (458), but it’s a nice, easy paddle. Wednesday morning the 9th looks better with a 4-foot WSW swell, clean conditions, and a bit more energy (560). That’s a solid morning session.

Thursday the 10th goes downhill fast. The wind swings onshore, the swell gets messy, and the energy jumps to 1326, but it’s all chop. Just skip it. That poor stretch runs through the weekend – Saturday and Sunday are blown to bits with strong onshore winds and big, lumpy waves. Monday the 14th morning offers a brief break: glassy conditions, an 8-foot west swell with 14-second period, and strong energy (2578). That’s another one for the experienced crew, but it’s clean.

The middle of the week (15th-17th) is a total loss – strong winds, onshore slop, and rain. Don’t even think about it. Then, on Friday the 18th, we get another beauty: glassy calm, 10-foot west swell, 15-second period, and massive energy (4017). That’s a Friday to circle. The Saturday morning after, the 19th, is also a treat with a clean 5-foot west swell and a gentle offshore breeze.

The very end of the run, on the 22nd and 23rd, looks good again with glassy or clean conditions and waist-to-chest-high west swells, but the real standout is that Friday the 11th. Get out there.

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.

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.
