The Lowdown
G’day, Rusty here. We’ve got a solid run of swell lining up for Dongara-Port Denison, but it’s a mixed bag of quality and conditions, so you’ll want to pick your moments carefully. The water temp’s sitting about average for this time of year, so nothing to fret about there.
The first real standout is Tuesday morning 11 August. We’re looking at a solid 13ft SW groundswell rolling in with a very long 16-second period – that’s proper energy (8486). It’s a little on the big side, so this one’s for experienced crew only. Wind’s a gentle ESE breeze, blowing cross-offshore, keeping the reef top clean. The catch with that long period is it might break a bit straight at the beach, but on a reef set-up like this, it should line up nicely. Crowds are sometimes a thing here, but on a Tuesday, you might have a bit more room.
Wednesday morning 12 August is another beauty. Swell drops a touch to 10ft, still SW and long-period (16 seconds), but now we’ve got a clean offshore from the east (15 km/h). It’s still expert territory size-wise, but the wave quality should be top-shelf – clean faces, plenty of energy (3876). This is the pick of the first week if you’re experienced.
We’ve got a bit of a lull coming in over the weekend with smaller swell and breezier conditions. Sunday afternoon 16 August is worth a mention though – the swell bumps back up to 7ft SW (16-second period, 2432 energy) and the wind goes glassy (WSW, 5 km/h). That’s rare and special. Conditions will be silky clean, but again, that long period might mean it’s better for the reef than the beach breaks.
Into the second week, Tuesday 18 August morning brings back 10ft SW swell with a light ENE cross-off breeze (10 km/h). Clean conditions, solid energy (4288), but still big enough for experienced surfers only. It’s a strong window.
Sunday 23 August morning is another standout late in the run – 10ft SW swell with a 17-second period, and a moderate offshore from the east (20 km/h). That’s a clean, powerful groundswell (4776) that should offer some excellent waves for those who can handle the size.
There’s a rough patch around Monday 17 August with onshore wind and rain – steer well clear. And Thursday 20 August sees a massive 15ft WSW swell but with strong cross-onshore winds, making it a lumpy, messy mess. That’s kite-surf territory, not paddle-friendly.
Overall, the best on offer is hands-down Wednesday morning 12 August for the clean offshore and solid but manageable swell, with Sunday afternoon 16 August as the sneaky glassy gem for those who can wait.
Stay safe, read the tides, and get amongst it.
