The Lowdown
Alright, let’s talk this in feet and miles per hour. This is Rusty, and here’s the straight-up on Dongara-Port Denison.
The next day or two are weak, but hang tight—there’s some heavy stuff on the horizon.
Saturday the 25th morning is a no-go. There's a weak 4 ft SW swell with a moderate cross-off breeze and poor conditions. Water temp is about 67°, a touch cooler than usual. But that afternoon turns glassy, and that same 4 ft swell picks up energy, so it’ll be clean and fun.
Sunday the 26th is marginal. A 3 ft groundswell with a long 16-second period in the morning, but cross-on wind kills it. The afternoon cleans up a bit with a 4 ft swell and cross-off wind, but it’s nothing special.
Monday the 27th morning pumps up to 8 ft of SW swell with clean cross-off wind. That’s expert-only territory. The afternoon stays at 8 ft and clean.
Tuesday the 28th is a standout. Offshore breeze all day, 7 ft SW swell with 14-second period and strong energy. The reef will be firing and hollow. Expect some crowd.
Wednesday the 29th backs off to 4 ft with a long 17-second period. Afternoon glass-off is clean but small.
Thursday the 30th afternoon is glassy with a 5 ft SW swell and solid energy. That’ll be smooth as silk.
Friday the 31st has big energy but the wind swings onshore, making it lumpy.
Saturday the 1st of August morning is a highlight: glassy, offshore, and an 8 ft SW swell with massive energy. Expert session only. The afternoon gets wrecked by a fresh SE wind.
From Sunday the 2nd through to Thursday the 6th of August, conditions are mostly blown out, too big, or onshore. The 6th sees a 15 ft WSW windswell with 45 mph onshore winds—that’s strictly for kite gear.
The second week is where it’s at. Friday the 7th of August morning shows a clean 12 ft SW groundswell with a 17-second period and cross-off wind. Huge energy. Experts only.
Saturday the 8th of August morning has offshore wind and an 8 ft SW swell.
But the absolute best is Sunday the 9th of August. Morning hits with an exceptional 12 ft SW groundswell, 17 seconds, offshore ENE wind, and an energy reading off the charts. That is a massive, clean, powerful swell. The afternoon holds at 12 ft with clean cross-off wind. If you’ve got the skills, that is the day. Circle it.
Rusty.

A general guide to surfing at Dongara-Port Denison can be found by selecting the local surf guide option on the grey menu.

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.
