The Lowdown

G'day, Rusty here, and we're looking at a solid run ahead for Cobden Breakwater. The water's sitting right on 54°, which is bang on average for this time of year, so no surprises there. The pattern starts quiet, builds to a real standout session mid-period, and then serves up another solid pulse right at the end. Let's get into it.

Monday the 10th kicks off pretty average. That morning rain shower with a cross-on wind means the 3ft swell from the west is messy, and the tide's likely doing no favours either. The wave energy is moderate (777). It's a bit of a write-off.

Tuesday the 11th is the first flicker of hope. Morning sees 3ft from the west-southwest with a clean offshore easterly breeze – clean waves, light wind. By the afternoon it goes glassy with a long period 18-second groundswell pushing in at 2ft from the west. The energy is moderate (332). It's small, but that glassy surface will be a treat for anyone on a longboard.

Wednesday the 12th morning holds clean, 3ft from the west-northwest with an offshore breeze. Then Wednesday afternoon is where it gets real. That swell jumps to 10ft from the north-northwest with a moderate 11-second period and a gentle offshore wind. The combined energy is strong (1803). This is expert territory – over 8ft, so only for the experienced crew. The break is fairly consistent, but crowds are rare here, so you might have it nearly to yourself. This is the first standout: big, clean, and powerful.

Thursday the 13th is still good. Morning has 5ft from the northwest with a clean cross-off breeze. The afternoon goes glassy with 5ft from the northwest. Energy is moderate (676-728). Very clean, very surfable.

Friday the 14th backs off. Morning is clean but only 2ft from the west-southwest, and the afternoon turns cross-on with a 19-second period groundswell that'll likely wall up on this breakwater setup. Energy is moderate (387-676). Not the best.

Now, Saturday the 15th is the real standout. Morning brings 8ft from the west with an 18-second very long period groundswell, clean with a cross-off breeze. The energy is strong (3273). This is excellent, powerful surf for experienced surfers. The long period will give it real punch and shape. The afternoon jumps to 8ft from the west-southwest but goes onshore, so it'll get messy. The morning session is the one.

Sunday the 16th drops a bit but stays punchy. Morning has 7ft from the west with a moderate breeze, clean enough but the wind picks up. Energy is strong (2036). It's still got power but the wind is a factor. The rest of the week from Monday 17th through to Saturday 22nd offers smaller, cleaner waves – around 3ft to 5ft, mostly with offshore or cross-off breezes. Not huge, but fun for intermediate surfers. Energy ranges from moderate (284) to moderate (815).

Then Sunday the 23rd and Monday the 24th show another pulse. Monday morning the 24th has 3ft from the west but with a 19-second period and clean conditions – energy is moderate (795). Monday afternoon jumps to 6ft from the west-southwest with a 17-second period, but a light cross-on wind. Energy is strong (2308). That's a solid swell, but the wind might chop it a little.

Tuesday the 25th finishes the run with 5ft from the west-southwest, clean with a moderate cross-off breeze. Energy is strong (1216). A good way to end the outlook.

So, if you're looking for the best of the bunch, it's Wednesday afternoon the 12th for the big, clean, expert-only stuff, and Saturday morning the 15th for that long-period, powerful groundswell with clean conditions. Both are absolute rippers for those who can handle it.

Stay salty,
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.

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.
