The Lowdown

Alright folks, Rusty here. Let’s get into it.

We’ve got a solid run of swell on the way for the stretch of coast around Dongara-Port Denison. The water is sitting at 66°, which is a bit colder than normal for this time of year, so don’t be shy with the rubber.

The first real chance to get wet comes Wednesday morning, the 29th of July. The swell is a clean 4ft from the SW, with a very long period of 17 seconds. That’s proper groundswell energy (1793), which is a lot of grunt for a reef setup. The wind is a fresh 19 mph cross-off, keeping things clean. The afternoon cleans up further with the wind dropping to a light breeze, making the 4ft SW swell look excellent for experienced surfers. This is a good start.

Thursday the 30th is a bit of a write-off. The wind swings onshore in the morning, and the 5ft swell gets a messy cross-chop. The afternoon sees a 5ft wave with a light onshore breeze.

Friday the 31st of July is a standout. The morning is glassy, with a 6ft SW groundswell rolling in at 17 seconds. The energy is pumping (2117), and the wind is dead calm. That’s a session to set an alarm for. The swell pushes up to 7ft in the afternoon, but the wind comes onshore, so stick to the morning.

Saturday the 1st of August has a solid 8ft SW swell, but the wind is a moderate cross-off in the morning, keeping it clean. The afternoon gets messy with a cross-shore chop. Sunday the 2nd is similar – 8ft in the morning with a clean cross-off, but the afternoon is light and crossed up.

We’ve got a bit of a lull on Monday the 3rd of August, with the swell dropping to 6ft but still clean with a cross-off wind. Excellent for the experienced crew.

Now, Tuesday the 4th of August sees a jump in size. A 8ft SW groundswell with a very long 18-second period hits in the morning, but the wind is onshore. The energy is strong (3821), but the wind is a problem. The afternoon is an 8ft swell with a cross-shore wind.

Here’s where it gets interesting. Wednesday the 5th of August morning is a beauty. An 8ft SW swell with a light cross-off and a clean surface. The energy is huge (3263), and this is an excellent option for experienced surfers. The swell is over 8ft, so this is expert territory.

The following few days get big and messy. By Thursday the 6th of August afternoon, the swell is 12ft and the wind is howling onshore. Friday the 7th of August sees 13ft SW swell with a cross-on wind, and the energy is colossal (8365). It’s big, but it’s also a mess. Saturday the 8th is a write-off with 28 mph onshore winds.

Sunday the 9th of August cleans up a bit. The morning has a 13ft WSW swell with a clean cross-off. The afternoon sees a 15ft SW swell with a gentle cross-shore, and the energy is massive (7940). This is a big, powerful, expert-only wave.

Now, the true standout of the whole outlook is Monday the 10th of August. The morning is a 20ft SW groundswell with a 20-second period. The energy is astronomical (27587). The wind is light offshore, and the surface is clean. However, the swell is too big for this break. It’s only for the most experienced chargers. The afternoon is the same story – 20ft, clean, offshore, but too big.

Tuesday the 11th of August is the pick for the experts. The morning has an 12ft SW swell with a moderate offshore wind, clean as a whistle. The energy is still massive (7482). This is an exceptional, expert-only session. The afternoon is a 10ft swell, still clean, but slightly smaller.

The rest of the outlook drops in size. Wednesday the 12th of August is a 6ft swell with a clean offshore, good for experienced surfers. The last few days of the second week, from Thursday the 13th of August, see the swell building again to 10ft and 13ft, with clean winds, but the energy is still strong.

So, the best on offer is clearly the glassy 6ft on Friday the 31st of July for the average crew, and the massive, clean, offshore 12ft on Tuesday the 11th of August for the experts. The 20ft on the 10th is a beast, but it’s too big for this spot.

Rusty.

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.
