The Lowdown

G’day, Rusty here. Alright, it’s gonna be a bit of a mixed bag over the next couple of weeks at Cobden Breakwater. There’s some solid swell on the table, but the wind and conditions are gonna chop and change. We’re starting off with a bit of a gap here – no real surf worth paddling out for until Thursday morning the 27th of August.

Okay, Thursday morning the 27th is where it starts to get a little interesting. We’ve got a 6ft swell rolling in from the WNW, and the wind is blowing offshore from the east at 12 mph. That’s going to make for some clean lines. The water temp is sitting at 55°F, which is right about average for this time of year. The combined swell energy is moderate (707), so there’s some push behind it. This morning window is the standout of the first week – it’s gonna be your best shot at a clean, fun session.

The next real highlight, and the best on offer across the whole outlook, lands on Saturday morning the 29th of August. Now this one’s a beauty. Swell drops to a manageable 5ft out of the WSW, and the wind goes totally glassy – barely a breath from the ENE at just 3 mph. You’ll be looking at clean, smooth faces with that moderate swell energy (664). This is the one to circle on the calendar. Keep in mind crowds are rare here, so you might have it to yourself.

After that, the swell picks up quick. Friday the 28th of August morning has a big 12ft NNW swell (3124 combined energy), but the wind is cross-shore from the NW at 12 mph and it’s simply too big for the break – experts only if you’re game. By Sunday the 30th, it gets messy with strong onshore winds.

Moving into the second week, there’s a promising window on Monday the 7th of September. Monday afternoon sees a 5ft W swell with a light offshore breeze from the east at 6 mph. Clean conditions and solid energy (755) – that’s a good bet for a late session.

Then Tuesday the 8th of September morning is small but clean – 3ft from the west, offshore wind from the NE, glassy conditions. Not a lot of power (299), but it’ll be a fun one if you’re on a log.

The last standout worth a mention is Wednesday morning the 9th of September. A solid 10ft WNW swell (1759 combined energy) with clean offshore wind from the ENE at 6 mph. That’s excellent for experienced surfers, but remember, when it’s over 8ft, it’s only for the crew who know what they’re doing.

So, bottom line: Thursday morning the 27th and Saturday morning the 29th are your true standouts in the first week. Second week, keep an eye on Monday afternoon the 7th and Wednesday morning the 9th, but those long-range calls are a bit more touch and go. Stay keen, Cobden.

Rusty.

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.

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.
