The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks at Dongara-Port Denison (Australia).
Right off the bat, we’ve got a solid run of swell heading our way, but it’s gonna be a bit of a mixed bag with the wind. The water temp’s sittin’ at 66.7°, which is pretty much what you’d expect for this time of year – nothing wild going on there.
We kick things off on Sunday the 6th with a big 10ft SW groundswell, but a fresh SSE breeze is keeping it cross-off. It’s got some serious energy behind it (3355), but the conditions are only marginal, so don’t expect perfection.
Monday the 7th is where the real power shows up. Morning session sees a massive 10ft SW swell with a very long period of 17 seconds, and the energy reading is through the roof at 5180. That is some serious grunt. The wind is SE at 12 mph, cross-off, keeping things reasonably clean. This is a standout – for experienced surfers only, mind you, that size is not for the faint-hearted. The afternoon holds similar size and a slightly shorter period, but the wind picks up a bit.
Tuesday the 8th stays solid at 10ft, but the wind is howling from the ESE at 22 mph in the morning. That’s a fresh breeze and cross-off, but it’ll be a battle. Energy is still massive (4084).
Now, Wednesday the 9th is the one that’s got my heart racing. We’ve got a 7.9ft SW swell in the morning dropping to 7.2ft in the afternoon, and the wind turns offshore from the East at 22 mph. That’s fresh offshore and clean. The energy is still well up there (2866 and 2197). This is the best of the bunch for the first week – proper waves, clean faces, and that offshore breeze will have the lines looking sexy.
After that, the swell starts to back off a bit. Thursday the 10th is smaller at 5.2ft, still a nice SW groundswell but the wind goes cross-on in the arvo. Friday the 11th is a write-off with onshore wind, and Saturday the 12th stays onshore with a 7.2ft bump that’s just messy.
Sunday the 13th morning looks promising again with a clean 6.9ft SW swell, light SE breeze and a good 14-second period. That’s a nice, surfable size with decent energy (1761). But it’s the morning of Monday the 14th that’s the absolute gem for the second week. The wind goes glassy – dead calm from the SE at just 3 mph – with a 7.5ft SW swell and solid 2201 energy. That is a magic window for experienced surfers, and the conditions will be as clean as a whistle. If you can get out there, that’s your day.
The rest of the week gets a bit bumpy with onshore or cross-shore winds, and the swell stays between 6.2ft and 8.2ft, but nothing really cleans up like that Monday. There’s a big pulse coming in on Monday the 21st with a 11.5ft SW groundswell and an insane 8317 energy reading, but the wind is howling onshore from the WSW at 12 mph. That’s a no-go for paddle surfing – that setup looks way more interesting for the kite crew.
So to wrap it up: if you’re looking for the standout, it’s Wednesday the 9th for the offshore winds and solid swell. The second standout is that glassy Monday morning on the 14th. Everything else is either too windy, too big for beginners, or just plain messy.
Stay stoked.

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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
