The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for Dongara-Port Denison over the next couple of weeks. There’s a rough start, but some absolute gems are hiding in this run.
First up, the first few days are a write-off. Friday the 7th and Saturday the 8th are messy with strong onshore winds and big, lumpy swell. You’re looking at 8ft to 15ft of SW swell, but the wind is just tearing it apart. Not worth paddling out. The combined wave energy is moderate to strong (3528 to 8210), but it’s all chop and no shape.
Then we hit the real standout. Sunday the 9th is the one you wait for. The wind goes glassy – dead calm – early morning, with a 13ft SW groundswell rolling in at a very long 17 seconds. That’s proper energy, 9317 on the combined scale, and it’s going to be glassy clean. This is for expert surfers only at that size, but if you’ve got the skills, this is a session to remember. The offshore wind at Dongara-Port Denison is a reef setup, so that long-period swell should wrap in nicely. It’s fairly consistent here, but crowds are sometimes an issue, so get in early.
Monday the 10th gets blown out again with strong onshore wind and poor conditions, so give it a miss.
Now, Tuesday the 11th is another huge standout. Morning brings a 16ft SW groundswell with a 16-second period, and clean cross-off winds from the SE. The combined energy is massive – 14274 – that’s strong. Again, this is only for experienced surfers; beginners will be in way over their head. The afternoon stays clean with light cross-shore breeze, but the size is still 16ft. It’s a big-water day.
Wednesday the 12th through to the 14th offers more good surf, with offshore and cross-off winds keeping things clean. Swell drops from 12ft to 8ft, with moderate combined energy (3571 to 5953). These are excellent for experienced surfers, and the lighter winds mean it’s a lot more manageable. The 14th has a clean afternoon with a light offshore breeze and 8ft swell – a nice one for a solid session.
After that, there’s a lull. The 15th and 16th are smaller, with onshore wind and only marginal conditions. Swell drops to 6ft–8ft, but the wind and chop spoil it. Not worth the drive.
Then, the 17th and 18th pick up again. Monday the 17th morning is clean with offshore wind and 8ft WSW swell, moderate energy (3832). The 18th Tuesday morning has a 13ft WSW swell, but it’s cross-on, so it’ll be a bit bumpy, though still surfable for the keen.
Finally, the 19th of August Wednesday morning is another glassy dawn patrol, with 12ft SW groundswell at 17 seconds. Combined energy is strong (6631), and it’s glassy. This is another one for the experts, but what a way to finish the window.
Overall, the absolute best on offer is Sunday the 9th and Tuesday the 11th. Those are the days to circle. The rest of the run has plenty of clean, smaller windows for experienced surfers, but the first week is where the magic is. Water temp is about average for this time of year, no major anomaly to report.
Stay stoked, and get on that Sunday glass.
