The Lowdown
Alright mates, Rusty here. Let’s break down the next couple of weeks for Cobden Breakwater.
Water temp is about 54°F, which is dead average for this time of year, so no funny business.
We start off slow. The first real chance to get wet is Wednesday the 29th of July. Morning has clean 3ft swell from the WSW, a long 14-second period, and a light offshore breeze. Combined energy is 608 (moderate). Afternoon picks up to 5ft from the WSW, still 14 seconds, but the wind goes cross-off. That’s the warm-up.
The big standout is Thursday the 30th of July. The morning has 4ft from the W, 13-second period, and a gentle offshore wind from the NE. Combined energy is 726 (moderate). It’s clean, it’s got push, and it’s gonna be fun. The afternoon gets bigger – 8ft from the NW – but the period drops to 8 seconds and the wind cranks from the NNE at 30 km/h. Choppy and messy. Only for the hardcore.
Friday the 31st is a total mess. Swells over 15ft with strong cross-onshore winds, combined energy up above 14,000 (very strong). That’s a big washing machine. Leave your shortboard at home.
The absolute best on offer is Saturday the 1st of August. The morning has 7ft from the W, 11-second period, and a light cross-offshore breeze from the SE. Combined energy is 1202 (moderate-strong). It’s clean and powerful – excellent for experienced surfers. The afternoon glasses off with 6ft from the W, 10-second period, and a glassy SSW breeze at 5 km/h. Combined energy 572 (moderate). That afternoon session is as good as it gets – smooth, clean, and solid.
Sunday the 2nd drops to 4ft, shorter period, but still clean in the morning. After that, a quiet spell.
Monday the 3rd of August brings a long-period groundswell – 4ft from the WSW but with a massive 18-second period. Combined energy 1069 (moderate-strong). At this breakwater, that long-period energy can be a bit tricky, but it’ll be clean with a light offshore breeze. The afternoon stays clean with a 17-second period.
The 4th and 5th are smaller, clean, but nothin’ to write home about. Then from the 6th through the 11th of August, it’s mostly flat or weak. Swells under 2ft, combined energy under 200, often onshore or messy. There’s a little 2ft swell on the 8th with a 15-second period that’s glassy in the afternoon, but it’s marginal.
Then, like a gift, Wednesday the 12th of August rolls in. The morning has 5ft from the W with an 18-second period, combined energy of 1792 (strong) and clean. The afternoon is glassy, 5ft from the W, 18-second period, 1823 combined energy. That’s a proper, clean, long-period swell for the experienced crew. That’s the one to circle on the calendar, though it’s far out.
So, if you’re lookin’ to paddle, Saturday the 1st of August is your day. The 12th of August is a promising long-range bet. The gaps between good days are a few days, but it’s not a total drought – just gotta be patient.
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.
