The Lowdown

Alright, Rusty here. Let’s have a look at what’s coming up for Cobden Breakwater.

Right off the bat, we’ve got a solid run of surf starting Wednesday morning. The water is sitting at 55°, which is basically normal for this time of year, so nothing wild there.

Wednesday morning is looking sweet. We’ve got a clean 5ft swell from the WSW, with a period of 11 seconds, and a light cross-off breeze from the East. The wave energy is decent too, sitting at 613 (moderate). Expect very good surf conditions. The afternoon gets even better – the wind goes glassy, coming from the West at just 6 mph, with a 4ft WSW swell. That glassy surface is a massive plus, making for some clean, smooth lines. This is a great start.

Thursday morning is a write-off for me. The wind swings onshore from the SW at 16 mph, pushing a lumpy 8ft swell. The energy jumps up to 1197 (moderate), but the onshore wind will ruin it. The afternoon is a bit better, with a cross-on breeze and a 8ft swell from the West, but the period drops to 9 seconds and the wind is messy. It’s marginal at best.

Now, Friday 11th September is the standout. The morning is pure glass – zero wind from the East. We’re looking at a 10ft swell from the West with a very long period of 18 seconds. That’s a proper groundswell, packing a massive 5618 (strong) energy. This is exceptional surf, but it’s only for expert surfers – that size and power is no joke. The long period means it could be a bit straight at the break, but with those conditions, the power will be incredible. The afternoon is also excellent, with an 8ft swell and glassy conditions, perfect for experienced surfers.

Saturday 12th September is a bust. The wind is onshore and strong, blowing 16-19 mph, and the swell is a messy 13ft. The energy is huge (7216), but it’s a total washout. Sunday the 13th could be a redemption. The morning is glassy again, with a 5ft W swell at 16 seconds. That’s excellent for experienced surfers. The energy is still strong at 2171, so the waves will have plenty of punch.

Monday 14th September morning is another glassy gem. The wind is dead calm, and we’ve got a 6ft W swell with a 15-second period. It’s clean and glassy, excellent for experienced surfers. The energy is 1430 (strong). The afternoon goes onshore, so get out early.

After that, the forecast gets messy. The week of the 15th to the 20th is mostly poor. Strong onshore winds, big lumpy swell, and a lot of rain. The swell is too big and blown out for most. There’s a small window on Tuesday the 15th morning with a tiny 2ft swell, but it’s not worth getting wet for.

The next real glimmer of hope is on the 22nd of September. Tuesday morning has a clean 7ft W swell with a 10-second period and a light offshore breeze from the NE. That’s excellent for experienced surfers. The energy is moderate at 1513. The 23rd of September Wednesday morning is also a standout in the second week. An 8ft W swell with a 16-second period, light cross-off wind, and energy of 3422 (strong). That’s an excellent prospect for experienced surfers, but it’s a long way out, so keep an eye on it.

So, overall, the best bet is to hit Friday 11th September morning, or Sunday 13th September morning. The first week gives you the most reliable, glassy conditions. The second week has some promising days, but they’re less certain.

Rusty.

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.
