The Lowdown
Righto, let’s have a look at what’s on the cards for Cobden Breakwater over the next couple of weeks.
First up, the water temp is sittin’ about average for this time of year, so no nasty surprises when you hit the water.
The pattern ahead is a bit of a mixed bag. We’ve got some real decent size comin’ through, but most of it’s gonna be blown out or just plain too big for the break. The first real chance to get in the water that’s worth your time is Wednesday the 2nd of September. That morning is lookin’ glassy – glassy, mate – with a clean 7 ft swell pushin’ in from the west, period around 13 seconds. That’s a proper groundswell, plenty of energy (1736), and with no wind messin’ it up, the break will be shapin’ up real nice for experienced surfers. This is the standout session of the whole run.
Now, you gotta be patient after that. Thursday the 3rd and Friday the 4th are marginal with crummy onshore or cross-off winds. Then we hit a real ugly stretch from the 5th right through the 7th where the swell is huge – well over 10 ft – and the wind is just honkin’ onshore. That’s a hard pass unless you’ve got a death wish. There’s a couple of windows on the 6th (Sunday) that say “wind and tide favorable,” but at 12 ft to 13 ft, this spot is just too exposed for that size.
Right, fast forward a bit. After a poor run on the 8th, we get another beauty on Wednesday the 9th of September. The morning has clean 10 ft swell from the northwest with light offshore flow, and the afternoon goes glassy again with a solid 8 ft NW swell (1934 energy). That afternoon session is world-class for the experienced crew, with those long-period lines (10 seconds) wrappin’ in clean.
Thursday the 10th also has a tidy morning with 5 ft swell – might be a bit weaker on energy (732), but clean and a nice size for intermediates. The 11th is marginal again, but then Saturday the 12th of September throws up a sneaky little morning: only 4 ft from the west, but with a clean offshore breeze. Low energy (392) but a fun little window if you’re on a longboard.
From there, things go south again with big rain and strong winds. The last day in the window, the 13th, is a no-go with 15 ft from the WSW and a fresh onshore breeze.
So overall: the real highlights are the Wednesday the 2nd morning glass-off and the Wednesday the 9th afternoon glass-off. Any other clean slots are small or a bit average. Keep your eyes peeled for those two windows, because that’s as good as it gets.
