Updates in hr min s Forecast update imminent
G’day, Rusty here. We’ve got one spot on the radar for the next couple of weeks: Cobden Breakwater. The water temp is sitting at about 56°, which is average for the season, no surprises there. The outlook starts off mixed, but there are a couple of sessions that’ll get the blood pumping.
First up, Saturday morning (July 4th) – we’ve got 8ft swell from the WNW at 11 seconds. That’s a solid groundswell with serious energy (1709), but the wind is a fresh NNE breeze at 19 mph, blowing cross-offshore. It’s clean, but 8ft is a lot for this break, and the wind makes it a bit marginal. Not the pick.
Now, Sunday afternoon (July 5th) is the standout for the first week. The wind drops to glassy calm, and we’ve got a 8ft swell from the WNW at 10 seconds. Moderate energy (1554), but with zero wind, the conditions will be pristine. This is a solid intermediate-to-expert wave – 8ft is getting up there, but the clean faces will make it a ripper. If you’ve got the skills, this is the session.
Monday (July 6th) sees a big jump – 10ft in the morning from the west, with a super long period of 16 seconds. That’s very long period groundswell, and the combined energy is cranked to 4136. But the wind is a gentle cross-shore, and the comment flags marginal conditions due to tide. This is heavy, powerful stuff – only for experts, and even then, it might be a handful. The long period will make it wall up at the breakwater.
For the second week, it gets smaller but cleaner. Thursday afternoon (July 15th) is the longer-range standout. We’ve got 6ft from the west, but the period jumps to 17 seconds – that’s a very long period, and the energy is 2583. The wind is light offshore from the ENE at 6 mph, so it’ll be glassy clean. This is a proper groundswell, and at Cobden Breakwater, that long period will set up beautifully. It’s listed as excellent for experienced surfers. Mark it, but it’s a week and a half away, so keep checking.
After that, it fades. From July 17th through the 19th, we’re down to 3ft to 3ft swells from the WSW, with light to moderate winds. Clean enough for a small wave if you’re keen, but nothing special.
The best on offer is Sunday afternoon (July 5th) for a glassy 8ft wave, and that Thursday July 15th session for the long-period offshore gem. Cobden Breakwater is fairly consistent, so even the smaller days can surprise. This window has its highs and lows, but there’s fun to be had.
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.
