The Lowdown
Alright, this is Rusty comin' at ya from the desk. Let's have a look at what's on the cards for the next couple of weeks.
Alright mate, we're looking at a solid run of swell for Dongara-Port Denison, but the wind is gonna be the real talking point. For the first week, the sea is absolutely pumping with energy, but a lot of it is coming with onshore or cross-onshore winds that'll chop it up. We do have a couple of windows of clean conditions, though, so you gotta be picky. The water is sitting at 66°F, which is a bit colder than normal for this time of year, so don't forget the steamer.
The first real standout is Saturday morning, the 1st of August. We got a 8ft swell from the SW with a long 15 second period, and the combined energy is pumping at 2469. The wind is a light ESE breeze at 10 km/h, coming cross-offshore, so the waves will be clean. This is setup for the more experienced crew, as it's a bit of size, but the quality is there. It's a reef break, so it'll handle that long-period energy well.
Sunday the 2nd has a similar size swell, 8ft from the SW, but the wind swings ENE at 25 km/h in the morning, which is still cross-off, but that breeze is a bit stronger so it won't be as glassy. The combined energy is still solid at 2598. It's a bit more on the edge for the conditions.
We hit a bit of a rough patch from Monday the 3rd through to the end of the first week. The wind goes onshore and the waves get lumpy and choppy, even though the swell size stays up. Not a great time for a paddle.
Now, get this. Wednesday the 5th of August is a beauty. The morning is looking clean with a 7ft SW swell, long 16 second period, and a glassy ENE breeze at only 5 km/h. The energy is at 2404. This is a proper window for some good, clean waves. The crowds are listed as "sometimes" here, so you might have a few mates out, but it won't be a circus.
Things get a bit wild for the next few days. The swell jumps up, but the wind stays ugly. Thursday the 6th morning has a massive 12ft SW swell with a solid 17 second period and energy through the roof at 6255, but the wind is howling onshore from the WSW. That's a no-go for me. This kind of size and power is only for the absolute experts, and even then, it's a washing machine.
The big daddy is on Sunday the 9th of August. The morning sees a 21ft monster from the WSW with a 19 second period. The energy is insane at 58897. The wind is offshore from the ESE at 10 km/h, so it would be clean. But, and this is a big but, the forecast says it's too big for this break. That's a no-go zone for paddle surfing. This is more of a tow-in or a spectator sport, or maybe something for the kite crew if you're into that kinda thing.
The second week settles down a bit. Wednesday the 12th looks good. 8ft swell from the SW with a 17 second period, and the wind is offshore from the E at 20 km/h. Clean conditions with 2811 energy. Good for the experienced lot.
The real standout in the second week is Thursday the 13th of August. The afternoon session is absolute magic. An 8ft SW swell with a very long 19 second period, and the wind is offshore from the E at just 10 km/h. Clean, light, and the energy is 5017. This is a call for the experts, but it's as good as it gets on paper. Just remember, this is a long-range call, so it's a bit less certain than the start of the week.
Sunday the 16th brings another big pulse of 15ft from the WSW with a 17 second period, but the wind is a strong SSE cross-off at 30 km/h. It'll be clean, but that's a lot of power and a lot of breeze. That's a big call for the top crew.
Overall, the best bets are the clean windows on the 1st, the 5th, and the 13th. The rest of the time, you're fighting the wind or the size.
Rusty out.

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.
