The Lowdown
G’day, I’m Rusty. Let’s get into it.
We’ve got a ripper of a 16-day window ahead for Dongara-Port Denison. The reef here is exposed to the west, so it’s all about that SW groundswell and the right wind. The water is sitting at 66°F, which is a bit colder than usual for this time of year, so you’ll want a slightly thicker wetsuit. The first few days are a write-off, but once that easterly offshore kicks in, it’s game on.
Saturday morning the 8th is a mess. That 15ft SW swell is pulsing with a combined energy of 8354, but a strong SSW breeze at 28 mph is making it a cross-onshore disaster. Poor surf, full stop. Saturday afternoon is no better, the wind drops a bit but still cross-onshore and lumpy. Forget it.
Then Sunday morning the 9th – this is the first standout. The breeze swings to an easterly offshore at just 6 mph, right into that 13ft SW swell at 17 seconds. The combined energy is massive at 9655. This is deep, clean groundswell with no wind, but 13ft is over 8ft, so this is expert territory only. For the crew that can handle it, it’s as good as it gets. The afternoon drops to 12ft but the wind turns light cross-onshore, so it’s a bit less clean.
Monday the 10th is a write-off – onshore winds and rain. Tuesday the 11th picks up again with a screaming 15ft SW swell, 16-second period, and easterly offshore wind at 6 mph. Combined energy is 11280 – that’s a beast. Another one for experts only. The afternoon stays solid but with a light cross-shore, still good.
Wednesday the 12th morning is clean with a light offshore breeze and 12ft SW swell, combined energy 5189. Still a big wave, not for the faint-hearted. Thursday the 13th morning offers 8ft SW swell with a gentle offshore, clean and excellent for experienced surfers. That’s a bit more manageable.
Friday the 14th morning is another beauty – 10ft SW swell at 17 seconds, moderate easterly offshore, clean. Combined energy 4599. Excellent for experienced surfers. The afternoon stays clean with a light cross-offshore.
Saturday the 15th and Sunday the 16th see the swell dropping to 7ft to 7ft, but the wind is all over the show – cross-off and cross-shore. Good for a fun paddle if you’re not picky, but nothing special.
Monday the 17th brings a new 8ft SW swell at 18 seconds – very long period – but the wind is light cross-shore, making it marginal. The afternoon is cross-onshore and choppy.
Now for the second standout. Wednesday the 19th morning – hold onto your board. A 15ft SW swell at 17 seconds, combined energy 12206, and a gentle cross-offshore breeze from the SE. That’s clean, powerful, and for experts only. It’s a long-range call but it’s looking promising. The afternoon gets a bit choppy with a cross-onshore.
Thursday the 20th morning is clean with a light cross-offshore and 10ft SW swell, combined energy 5140. Excellent for the experienced crew. After that, Friday the 21st and Saturday the 22nd are a write-off with strong onshore winds and rain. Sunday the 23rd morning has a 13ft WSW swell with a gentle cross-onshore, combined energy 7632, marginal but worth a look if you’re desperate.
Overall, the absolute best on offer is Sunday morning the 9th and Tuesday morning the 11th, with Wednesday the 19th morning as the long-range standout. If you’re an expert, mark your calendar. If you’re not, wait for the smaller days on the 13th or 14th.
Rusty.

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 Dongara-Port Denison 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.
