The Lowdown

Righto, cobber. Rusty here with the long-range outlook for the Cobden Breakwater. There’s a bit of a slow start, but the second half of the week and into the following week has some absolute crackers for the experienced crew.

The opening couple of days are a write-off, to be honest. Sunday the 13th is a no-go with rain and messy 8ft onshore slop. Monday the 14th isn’t much better with a tricky cross-onshore breeze. We’re looking at a gap of nothing worthwhile until the middle of the week.

The first real glimmer comes Tuesday morning the 15th. It’s only 4ft, but that ESE breeze is clean and cross-off, so it’ll be tidy for the intermediates out there.

Wednesday the 16th is where it starts to get interesting. The morning is clean and 5ft, but the afternoon is the standout of this first week: a solid 8ft from the WNW with a clean cross-off wind. The combined energy is pumping at 1226 (moderate wave energy). This is excellent for experienced surfers only – that size is getting up there. The water temp is 54°, about average for this time of year.

Thursday the 17th holds that form with excellent, clean conditions both morning and afternoon – 5ft to 6ft of solid WSW groundswell, period around 14 seconds. Combined energy is very strong (1818 and 1742). Light offshore breezes keep it all tidy.

But the true standout of the whole run? Friday morning the 18th. Glassy conditions, a clean 7ft of long-period W groundswell at 15 seconds, and combined energy hitting 2177 (strong wave energy). This is the pick for the experienced surfer – that long period will make for powerful, well-shaped waves at this break. It will be clean and uncrowded.

Saturday the 19th turns ugly fast – onshore winds and a massive 15ft in the afternoon, which is way too big for paddle surfing. This spot is exposed, and that kind of size with onshore wind looks more interesting for kite surfing than paddle surfing.

Sunday the 20th morning is a return to glory: glassy again with a solid 10ft W swell at 14 seconds, combined energy of 3456 (very strong wave energy). Another expert-only session, but it will be a ripper.

After that, the run gets inconsistent. Monday the 21st is windy and messy. Tuesday the 22nd has huge 12ft to 13ft swell with clean winds, but it’s just too big for this break. Wednesday the 23rd is a complete washout with strong cross-onshore winds.

The next real highlight is Thursday morning the 24th of September. Clean offshore ENE breeze, 8ft of W groundswell with a 15-second period, and combined energy of 2717 (strong wave energy). Excellent for experienced surfers.

Saturday the 26th offers a solid finish: both morning and afternoon have clean 7ft and 7ft W swell with good winds. Not the biggest of the run, but very surfable.

The final few days taper off with smaller swell and stronger winds, so get on it earlier. Keep an eye on that Friday the 18th and Thursday the 24th – those are the ones to circle.

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. If you surf the same spot (Cobden Breakwater) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
