The Lowdown

Righto, cobber, Rusty here. Let's have a look at what's on the table for the next couple of weeks.

We've got one spot to work with, and that's Cobden Breakwater. It's a breakwater setup, so it's a bit of a specialist wave – it can handle a good fetch of swell. The water temp is sitting about average for this time of year, nothing too wild.

The first real standout is the coming Saturday morning, the 15th of August. We've got a solid 8ft of long-period west swell rolling in at 15 seconds, and the energy is pumping (2753). The wind is a light cross-off from the southeast, which will keep things clean. This is a proper groundswell, so expect some power and longer lulls between sets. It's a fair size, so this one is for the experienced crew.

That Saturday arvo sees the wind swing onshore, so it gets a bit messy. Sunday the 16th morning is a bit blowy, but Sunday afternoon the wind drops back to a light cross-off again, with 7ft of west swell. Clean and workable.

Then we hit a bit of a lull. Monday the 17th through to the end of that week, the swell drops off. We get some smaller, cleaner windows – like Tuesday morning with 4ft, or Thursday morning the 20th with a light offshore wind and 4ft. The energy is weak to moderate (605). It's not a total write-off, but it's small and inconsistent.

The real event kicks off again on the 23rd of August. Sunday morning that week sees a jump in size with 8ft from the WNW, but it's getting blown out by a fresh nor'westerly. Not ideal. The 24th of August, Monday morning, is a weird one. The ocean is churning with 13ft of west swell and an energy reading of 3254 – that's a massive amount of juice. The wind is glassy, but the size is simply too big for this break. Unless you're on a big wave gun and have a death wish, this is a pass.

The 26th of August, Wednesday morning, that's the next genuine standout. We're back to 8ft of west swell (15 seconds), with a light cross-off from the east. The energy is strong again (2678). This is a ripper session for experienced surfers. The 27th of August, Thursday, also looks promising with a glassy morning and a 8ft west swell.

The last week of the month sees a shift in direction. The 29th of August, Saturday morning, brings in 10ft of north-northwest swell with a moderate energy (1959). It's a bit bigger, and the wind is a clean cross-off. Good for the experienced fellas again. The 30th of August, Sunday morning, is another solid option with 8ft from the northwest and clean conditions.

So, to sum it up: the best on offer is the Saturday morning of the 15th of August, and the Wednesday morning of the 26th of August. Both are solid, clean, powerful groundswells at Cobden Breakwater. Get around it if you've got the skills.

Rusty.

A general guide to surfing at Cobden Breakwater can be found by selecting the local surf guide option on the grey menu.

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.
