The Lowdown
Hey mates, Rusty here. Let’s talk about Dongara-Port Denison. It’s a reef setup that needs a proper SW push, and we’ve got a good run of it coming.
Water temp is about 66°, which is spot on average for this time of year, so don’t worry about a cold shock.
First decent look is Saturday the 29th in the morning. It’s a small one – just about 3 feet of glassy SW groundswell with a very long 20-second period. The wind’s a light cross-off, so it’ll be clean and easy. Good for a longboard or a fish.
The absolute standout is Sunday the 30th at dawn. We’ve got a solid 8 feet of smooth SW groundswell, 19-second period, and the wind is totally dead. Glassy as a lake. The combined energy is massive (3986). This is a serious session for experienced surfers. Beginners should sit this one out – that 8-foot set is no joke, and it’ll be a bit walled-up.
The onshore wind messes things up for the next few days, and we get a quiet spell around the 7th and 8th of September when the swell drops and the wind gets sloppy.
Then it gets heavy. Thursday the 10th of September we see a 15-foot SW groundswell. The morning is junk, but the afternoon brings a cross-shore that cleans it up. The energy reading is a ridiculous (11285). This is expert-only territory. The paddle out alone will be a mission.
The best of that big pulse is Friday the 11th of September in the morning. A clean 13-foot SW swell with light cross-off winds. The lineup will be organized but incredibly powerful. It’s going to be packed, but that’s the price for a wave this good.
After that, it settles back to a solid 8-foot range on Saturday the 12th with clean morning conditions, still too big for the groms, but perfect for charging.
Rusty.
