The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for the stretch ahead. This is a solid run of south-west groundswell, no doubt. The water’s sitting about average for this time of year, nothing wild going on there.
We get into it proper on Sunday the 16th of August, but it starts off a bit messy. Sunday morning’s got a clean 4ft SW swell with a 16-second period, but that NE wind is howling at 19 mph, a cross-off that’ll keep things a bit bumpy. The energy’s there (1212 total) but it feels like a warm-up, not the main event. Sunday afternoon, though, is where it gets tasty. That swell pushes up to a nice 7ft from the SW, same long 16-second pulse, and the wind drops right out to a glassy 3 mph offshore from the east. That’s the kind of afternoon you paddle hard for—clean, lined-up waves at Dongara-Port Denison, a reef break that likes this west in the swell. This is the standout session.
Monday the 17th is a write-off. Onshore wind and rain make a mess of things, so give it a miss. Tuesday the 18th, though, is a big one for the brave. Tuesday morning you’ve got a beast of a 12ft SW groundswell, period holding at 16 seconds, and clean offshore wind from the east at 6 mph. That’s expert territory only—big, powerful, and a lot of water moving (6262 total energy). If you’re not solid, watch from the carpark. Tuesday arvo the wind swings cross-on and it gets lumpy.
The next real highlight is Thursday the 20th. Another 10ft SW swell, 16 seconds, with clean cross-off winds in the morning. The energy is pumping (5406) and the conditions are clean. That’s another expert-level session but one for the books.
We wind down a bit after that. Friday the 21st still has fun 8ft to 10ft SW swell with offshore or clean cross-off winds—good for experienced surfers. Then Saturday the 22nd and Sunday the 23rd drop off a little, with smaller 7ft to 6ft swell but still clean. It’s rideable, but not the peak.
There’s a bit of a flat, windy gap Monday 24th and Tuesday 25th—nothing worth paddling out for. Wednesday the 26th sees a new pulse, with 7ft to 10ft SW groundswell and a longer 17-second period, but the cross-shore wind keeps it a bit messy. Still, for the keen, there’s waves.
Thursday the 27th cleans right up again with a 10ft SW swell and glassy cross-off winds. That’s another excellent morning for experienced surfers. The energy is solid (3728). Then things wind down toward the end of the fortnight, with a few smaller days before another pulse shows up. Saturday the 29th has a clean 8ft SW groundswell with a very long 18-second period—that’s proper groundswell, but for a reef like this it’ll be lined up and juicy. Sunday the 30th has a clean 8ft WSW swell with offshore wind, another top morning.
All in all, the best of the best is that Sunday afternoon the 16th for the combo of size, wind, and clean conditions. Tuesday morning the 18th and Thursday the 20th for the big, expert-only juice. Later in the run, Thursday the 27th and Sunday the 30th mornings are standouts too.
Rusty.

Information about the Dongara-Port Denison Surf forecast
The above surf forecast table for Dongara-Port Denison provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Dongara-Port Denison can be found by selecting the local surf guide option on the grey menu. Our Dongara-Port Denison surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Dongara-Port Denison) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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.
