The Lowdown
Alright, Rusty here again. Let’s talk Cobden Breakwater in feet and miles per hour.
We’ve got a slow start, so leave the board in the car for the first day or two. Monday the 3rd of August is a bust – a weak 4ft WSW groundswell with an 18-second period, but with 9 mph onshore wind and moderate energy, it’s messy. By the afternoon, a raw 10ft wind swell with a short 8-second period and 18 mph onshore wind is just ugly.
Tuesday the 4th is the first real window. Morning brings clean 8ft W swell at 10 seconds with light cross-offshore winds from the SE at 9 mph. That’s expert-only stuff. Afternoon drops to a cleaner 6ft.
Wednesday the 5th is a nice small day. A clean 3ft WSW groundswell at 13 seconds, light easterly cross-offshore winds at 6 mph. Smooth cruising.
Here are your standouts. Thursday the 13th – morning session delivers a clean 7ft W groundswell at 15 seconds with 9 mph cross-offshore winds and energy of 2251. That’s powerful, clean, and the pick of the forecast. Monday the 17th – morning is glassy with a 5ft W swell at 11 seconds and light ESE winds at 3 mph. Afternoon goes glassy flat calm with a 3ft WSW swell at 17 seconds – that’s a *really* long period groundswell. Expect long, clean, peeling waves at this breakwater.
Avoid the 12th of August – that 13ft swell with energy over 8000 is too big for most. And the 15th of August – a 20ft W swell with 11588 energy and 18 mph onshore wind is just dangerous.
Water temp is 54°F, right about normal for the season.
Best sessions: Thursday the 13th morning and Monday the 17th.
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.
