The Lowdown
Alright folks, Rusty here. Let's have a look at what's shaping up for our stretch of coast.
We've got a solid run of south-west swell lining up for the next couple of weeks, but it's gonna be a bit of a mixed bag with the wind. The water is sitting at 66° at the start, which is a bit colder than normal for this time of year, so you might want an extra layer.
The first real chance to get out starts Tuesday the 1st of September. We're looking at a 6ft SW swell with a long 16-second period, so there's plenty of energy in the water. The wind is a cross-off from the SSE at 9 mph, which should keep it reasonably clean at Dongara-Port Denison. It's a reef break, so that long period will wrap in nicely, but it's a bit on the bigger side for beginners.
Wednesday the 2nd sees similar 7ft to 7ft SW swell, but the wind swings more cross-shore, making it a little lumpier. The energy is still there, but it's not as clean.
Now, here's the standout window. Thursday the 3rd of September, the morning is looking glassy. We've got a 8ft SW swell with a 14-second period and a light NNW offshore breeze at 3 mph. The conditions are described as glassy. This is the pick of the early forecast for experienced surfers, but it's a reef, so that long period will work well. If you're a beginner, that 8ft might be a bit much.
The next few days get messy. Friday the 4th and Saturday the 5th are a write-off with strong onshore winds and a big, lumpy 10ft to 12ft swell. The energy is through the roof, but the quality is poor. This is more of a kite-surfing setup than a paddling one.
We get a clean-up on Sunday the 6th with a cross-off SE wind, but the swell is still a solid 12ft. It's a big, powerful swell, so only for the experts.
The real highlight, though, is looking at Monday the 7th of September. The wind is offshore from the ESE at 9 mph, and we've got a 10ft SW swell with a very long 17-second period. The conditions are described as exceptional for expert surfers. This is a serious groundswell, and it's going to be firing on the reef. The sets will be big and clean, but the long period means it'll be a bit fat and straight on a beach break – thankfully, we're on a reef, so it'll be epic.
Tuesday the 8th keeps the offshore theme going with a 10ft SW swell, but the period drops to 16 seconds. Still very good, with excellent conditions for experienced surfers.
The following week looks a bit more inconsistent. There's a drop-off in swell around the 9th and 11th, but then we get another pulse of significant energy around Saturday the 12th and Sunday the 13th. Saturday the 12th morning is looking promising with a 10ft SW swell and offshore E wind, but the period is a shorter 13 seconds. It'll be a bit lumpy in the afternoon.
The last true standout is Tuesday the 15th of September. We're looking at another 10ft SW swell, this time with a 15-second period, and a clean cross-off wind from the SSE at 9 mph. It's described as excellent for experienced surfers. That's a session to mark on the calendar.
So, to sum it up: the best windows are Thursday the 3rd of September morning for the glass, and Monday the 7th of September for the absolute peak of the swell. The later part of the second week, particularly Tuesday the 15th, also looks like a cracker. Keep an eye on the wind, and don't be afraid to wait for the clean ones.
Rusty.
