The Lowdown
Alright, this is Rusty, checkin’ out the waves for the Dongara-Port Denison spot over the next couple of weeks.
We’ve got some serious size comin’ in, but it’s gonna take a bit of patience to find the clean windows. There’s a solid, long-period groundswell from the SW that’s gonna be hittin’ for a good stretch, but a lot of the time the wind is gonna be a bit of a pain. The first few days are a mixed bag. The standout, the absolute one to circle, is Sunday, August 9th. That morning, we’re lookin’ at 13ft of SW swell with a 17-second period – that’s some serious, long-period energy, and the combined energy is a massive 9536. The wind is a light offshore from the ENE, just a slight air, so the surface will be glassy. This is for experienced surfers only, though – at 13ft, it’s not a day for the faint-hearted. The water temp is 66°, which is a bit colder than normal for this time of year, so you’ll want a good wetsuit.
The other big one to lock in is Tuesday, August 11th. Another morning with 13ft of SW groundswell, this time an 18-second period, and the combined energy is 9335. Clean offshore wind from the ESE, again, for the experts. The Thursday morning the 13th is also lookin’ good with 10ft and 18-second period swell, clean conditions, and a combined energy of 6153. That’s a solid session for the experienced crew.
Now, for the rest of it. The first few days from Tuesday the 4th through to Saturday the 8th are mostly onshore or cross-onshore winds, choppy conditions, and the swell is big but messy. The Saturday afternoon the 8th has a 13ft SW swell, but it’s a fresh cross-shore wind with a lumpy cross-chop – the combined energy is a whopping 14010, but it’ll be a battle. Not really a paddle surfer’s dream, more of a kite session if you’re into that.
After the 9th, the swell hangs around in the 8ft to 12ft range, but the wind goes back and forth. The Thursday morning the 13th is a highlight, as I said. The Saturday the 15th and Sunday the 16th are onshore again, and it gets a bit ordinary. The following week, from the 17th onwards, the swell starts to drop off a bit, but the wind is still messy. The Wednesday the 19th is just a write-off with strong onshore winds.
So, bottom line: if you’re an expert, lock in the mornings of the 9th, 11th, and 13th of August. That’s your best chance for some all-time, clean, heavy waves. The rest of the time, you’re gonna be pickin’ through a lot of chop and wind.
Rusty.
