The Lowdown
Alright, mate, Rusty here. Let's get straight into it.
The next couple of weeks are shaping up to be a proper run of solid, powerful southwest groundswell. There are a few bumpy, wind-affected days to sit out early on, but the real story is the weekend of the 9th and then that Tuesday the 11th. That’s where you want to be.
First up, at Dongara-Port Denison on Wednesday the 5th, we’ve got a clean morning with 8ft of southwest swell at 16 seconds. That’s a proper groundswell, carrying a heap of energy (2825). The water’s sitting at 66°, which is a bit colder than usual for this time of year, so don’t forget the boots. The light ESE cross-off wind will have it looking tidy, but it’s still a solid size, so it’s more for the experienced crew. The afternoon gets a bit messier as the wind swings onshore and it jumps to 10ft, so get your waves in early.
Thursday the 6th sees the swell hold at 10ft, but the wind is straight onshore out of the WSW. That’s going to put a bit of chop on it, making it a tricky one. Not the best call. Friday the 7th is similar – still 10ft but with a cross-on wind and a bit of rain around. It’s going to be lumpy and uninviting. Saturday the 8th is a write-off. The swell bumps up to 12ft, but we’ve got a strong 25 mph cross-onshore wind. That’s a mess. It’s pushing 15ft by the afternoon with a fresh cross-shore breeze, which is just a washing machine. I’d be giving that a wide berth.
Now, Sunday the 9th. This is the one that’s got me excited. The swell is still a chunky 15ft, but the wind drops right out, going light ENE cross-off in the morning and then glassy by the afternoon. The period stretches out to 17-18 seconds, so there’s a ton of energy in the water (11175). This is as good as it gets – big, clean, powerful surf. It’s a serious paddle and only for experts at this size, but if you can handle it, it will be unforgettable. The long period does mean it might be a bit straight at the beach breaks, but this reef should handle it beautifully.
Monday the 10th is a step down in quality, with fresh cross-shore winds and a dropping swell, so we’ll skip that. But Tuesday the 11th is another standout. The swell is back to a solid 13ft, and we’ve got a clean, gentle offshore breeze out of the east in the morning. The energy is still strong (8079), and it’s looking excellent. The afternoon brings a cross-shore wind, but the morning session is where it’s at.
After that, the swell backs off a bit but stays consistent. Wednesday the 12th and Thursday the 13th still have 10ft of swell with good offshore winds in the mornings, keeping things clean and fun for experienced surfers. Friday the 14th is similar. The following week starts to taper off in size, with the swell dropping to around 7ft by the 15th and 16th. The winds are a bit more variable, with some cross-off mornings and some bumpy afternoons. There are still some rideable waves, but the energy is definitely winding down.
The week after that, the 17th through the 20th, looks a bit more ordinary. The swell stays around 7ft to 10ft, but the winds are mostly cross-shore or cross-on, and by the 20th, we’ve got fresh onshores and messy conditions again. That's a week away, so keep an eye on it, but it’s not looking like a priority.
So, to sum it up: the standout days are Sunday the 9th and Tuesday the 11th. If you can only get out once, make it Sunday morning. It’s going to be big, but it will be as clean as it gets.
Rusty.
