The Lowdown
Alright, Rusty here. Let's break down the Dongara-Port Denison forecast.
We've got a solid south-west groundswell train running, but the wind is going to pick the winners and losers. It's a reef break, so it needs the right wind to really shine.
The first day to circle is this Sunday, August 30th. The water temp is about 69°F, which is normal for the season. We're looking at a solid 8ft SW groundswell with a very long 19-second period. The energy is huge, with a combined reading of 3987. The wind is glassy from the WSW at just 3 mph. That's a dream scenario for this spot. The swell direction is ideal from the south-west. It's big, though—over 8ft in the afternoon—so this is expert territory. The morning session is the one.
After that, it's a rough patch. From Monday through to the end of the week, the wind turns onshore and cross-shore, bringing choppy, lumpy surf. The swell is still there, but it's not worth paddling out for. Friday, September 4th, looks awful with strong winds and poor conditions.
Looking ahead, there's a serious chance on Monday, September 7th. We've got a 10ft SW swell with a 17-second period, and the wind is a clean offshore breeze from the east at 12 mph. The energy is enormous at 5695, and the forecast is exceptional for experienced surfers. This is a big, powerful groundswell on a reef with offshore wind—that's a standout. The crowds can be "sometimes" here, but the size will keep the numbers down.
Then, keep an eye on Thursday, September 10th. This is a long-range forecast, but it's a monster. We're talking an 12ft SW groundswell with an 18-second period, and the combined energy is off the charts at 8145. The wind is a light cross-shore from the NNW at 6 mph, which is workable. If this holds, it's going to be a huge day for the experts.
The rest of the second week has consistent swell, but the wind is a bit of a gamble, mostly cross-shore, so it's hard to lock in a perfect session. The early mornings will be your best bet.
Rusty.
