The Lowdown

Righto, Rusty here. Let's have a look at what's coming our way for Cobden Breakwater.

First up, the water temp is sitting at 55°, which is about average for this time of year. Not gonna need a thick steamer but you'll want a decent spring suit.

The next 16 days are a bit of a mixed bag for Cobden Breakwater. We've got some proper, hefty groundswells rolling in, but the wind and size are going to be a real challenge. The first week in particular is messy. Wednesday the 2nd is a write-off with a 6ft cross-on shorey and poor conditions. The combined swell energy is a massive 1231 - that's a lot of juice - but it's all for nothing with the wind. Thursday the 3rd afternoon cleans up a bit, with a 4ft swell from the WSW and a clean cross-off breeze. It's not huge, but the setup looks rideable. The swell energy is still moderate at 908.

The real story here is that for most of the first week and a half, the swell is just too big. We're talking 13ft to 15ft swells from Friday the 4th through to Saturday the 5th, with strong onshore winds. The combined energy is through the roof, hitting 5006 (very strong wave energy), but for a paddle surfer, it's a skunk. This setup looks more interesting for kite surfing than paddle surfing.

The standout window, and the one to circle on the calendar, is the Monday morning of the 7th. We get a clean, 6ft W swell with a 14-second period and a light cross-off breeze from the ESE. The energy is still a solid 2289 (moderate-strong), but the conditions are excellent for experienced surfers. The swell direction (W) matches up nicely with that optimum WSW direction, so the waves should have some shape. It's an exposed spot, so it'll cop the full force, but with that wind, it'll be lining up clean. Crowds are rated as 'rare', so you might have it to yourself.

After that, there are more opportunities on the 12th of September, with a clean 8ft W swell and a 16-second period, good for experienced surfers. The 14th of September morning also looks very good, with a glassy 5ft W swell. Further out, the 16th and 17th of September both have clean mornings with solid swell, but as with any long-range call, treat it as promising but less certain.

In the second week, things quieten down in size but remain very clean. The 13th of September is a bit of a letdown with smaller, cross-on swell. The 15th of September has a real special one: a 19-second period, 4ft swell from the WNW. That's a very long period groundswell, which will wrap around and hold up beautifully at a breakwater spot like this. The combined energy is 2019 (moderate), but the quality from that period will be incredible.

So, the best bet for a proper session is the morning of Monday the 7th. For a glassy, clean wave the morning of the 14th is a beauty. The long-period groundswell on the 15th is a real wildcard that could be world-class, so keep an eye on that.

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.
