The Lowdown

G'day, I'm Rusty, and I've got the lowdown on the waves coming our way for Cobden Breakwater.

First off, the water temp is sitting right around 55°F, which is pretty much bang on for this time of year, so nothing unusual there.

The first solid opportunity kicks off on Saturday, August 1st. We're looking at a clean 5ft swell from the west, with a period of 10 seconds and glassy conditions. The combined energy is moderate (433). It's a nice start to the period.

The real standout, the one you want to circle on the calendar, is the tail end of the forecast. Tuesday, August 15th, is looking like a serious session. The morning brings a solid 8ft swell from the west with a 13-second period, and the energy is pumping hard (2828). The wind is light offshore from the NE, making for clean waves. This is excellent for experienced surfers, and the crowds are rare, so you might have it to yourself. The afternoon sees it jump to 8ft (3219 energy), but the wind swings to a cross-shore, making conditions a bit more tricky.

Then, on Sunday, August 16th, the swell drops a touch but stays at a very respectable 6ft from the west, with a long 16-second period. The energy is still strong (1923). The morning has a clean cross-offshore breeze, and the afternoon goes glassy with light easterly winds. Again, excellent conditions for experienced surfers.

There are a few other days with surfable waves. Monday, August 4th, gets a clean 6ft west swell with a short period of 9 seconds (1027 energy) in the morning. The wind is cross-offshore, so it's a decent option. Thursday, August 14th, also offers a solid 4ft west swell (877 energy) with glassy conditions both morning and afternoon, giving you very good waves.

Now, a word on the 8ft+ days on the 15th: that's expert territory. The swell is powerful, and the long period (13-16 seconds) means it'll be a proper groundswell. At a breakwater, that should produce some well-defined lines, but don't paddle out if you're not confident.

For the rest of the period, there are a few small days (under 3ft) with clean conditions, but nothing to write home about. The run from the 5th through to the 12th sees wave heights mostly under 3ft, with a mix of cross-offshore and glassy winds, so if you're after a longboard and a quiet paddle, you'll find something, but it's not the main event.

Stay stoked, and keep an eye on that mid-August window.

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.
