The Lowdown
Alright mate, pull on the springsuit, here's the word for the Dongara-Port Denison stretch for the next couple of weeks.
We've got a solid run of swell coming, but the wind is going to call the shots. The first real standout window opens Thursday morning the 3rd. The wind is glassy out of the north at just 3 mph, and there's a clean 8ft SW groundswell with a long 15-second period rolling in. The water temp is about 67°, which is pretty normal for this time of year. This is prime for experienced surfers, but keep in mind, it's a reef break and at that size with long period, it's got some serious punch. The combined energy is strong, sitting at 2424 (moderate to strong wave energy). Crowds are a *sometimes* thing here, so you might have a handful of locals out, but a Thursday morning should be okay.
After that morning, the wind turns onshore and the quality drops hard. Friday, Saturday, and Sunday (the 4th, 5th, and 6th) are pretty much a washout for clean waves, with strong cross-onshore winds and messy conditions. The swell is still there, but it's not worth the paddle.
The next big highlight is Monday the 7th. We have a very long-period SW groundswell of 10ft at 17 seconds on Monday morning, with clean cross-offshore winds from the ESE at 16 mph. The energy is cranking at 5673 (strong wave energy). This is big, powerful, long-period stuff, and at a reef break, it's going to be an expert-only day. That long period means the waves will have shape and energy, but the sets will be big and heavy.
Tuesday the 8th and Wednesday the 9th mornings are also looking like the pick of the week. On Tuesday morning, clean offshore winds from the ESE at 16 mph with an 8ft SW swell at 16 seconds. Wednesday morning is even better, with an 8ft SW groundswell at 16 seconds and light offshore winds from the east at 12 mph. Both are rated excellent for experienced surfers. The energy is strong (2888 and 3175).
After that, the swell starts to drop. Thursday the 10th morning still has a clean 6ft SW swell with a light cross-offshore breeze, but the power is fading (1764). By Friday the 11th, the onshore wind is back and quality goes out the window.
There's a wildcard on the 12th and 13th. Saturday the 12th is blown out with a near gale, but Sunday morning the 13th has a big 10ft SW swell with clean cross-offshore winds. That's a big lump for a Sunday session, but worth a look if you're experienced. The energy is strong at 4523.
The final two days of the run, the 16th and 17th, are worth a look for a smaller option. The 16th Wednesday afternoon has a clean 7ft SW swell (13 seconds) with moderate offshore wind from the east. That's excellent for experienced surfers and much more user-friendly. The 17th Thursday is smaller, around 5ft, but still clean with cross-offshore winds.
If I had to pick just one day, it's Wednesday morning the 9th. That 8ft SW groundswell with clean offshore wind and strong energy (3175) is about as good as it gets for this spot. Monday the 7th morning is a close second for the brave, but that 17-second period makes it a beast. For the second week, keep an eye on the 16th afternoon for a cleaner, smaller session.
Stay safe out there.

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.
