The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the table for the Margaret River Mouth.

First up, the water is sitting at a touch warmer than normal for this time of year, around 66°, so you might not need the thickest wetsuit.

We've got a bit of a slow start, but things kick off on Wednesday morning the 29th. The swell is a modest 4ft from the SW with a solid 13-second period, packing a moderate energy punch (731). The wind is a cross-off from the NE, keeping things clean. It's a beginner-friendly wave, and it's very consistent here, so it's a good place to get a few. The morning is the pick, with the afternoon dropping a bit in size.

Thursday the 30th sees the swell drop back to 3ft. The morning is clean with a cross-off breeze, but the scores are marginal. The afternoon gets a bit messy with a cross-shore wind. It's a bit of a lull.

Friday the 31st is a write-off. The swell jumps up to 7ft, but the wind swings onshore and gets fresh, making it lumpy and poor. Not worth a paddle.

The first weekend of August is a mixed bag. Saturday the 1st has a solid 6ft-8ft SW swell, but the wind is tricky. The afternoon looks the best with a clean cross-off breeze and a bigger 8ft swell. Sunday the 2nd cleans up nicely with a cross-off NE wind, and the 5ft-4ft swell is very manageable. The afternoon session is the pick for a relaxing surf.

Now, if you're looking for a standout, you have to circle Monday the 3rd of August. The morning is an absolute gem. The swell is a clean 3ft from the SW with a long 15-second period, and the wind is glassy. Absolutely dead calm. That's a window of pure, clean lines. It won't be huge, but the quality will be through the roof.

The rest of the first week stays punchy, but the wind is a constant battle. Tuesday the 4th has a 6ft swell but onshore wind messes it up. Wednesday the 5th is similar. By Thursday the 6th and Friday the 7th, the swell cranks up to 8ft and then a massive 13ft, but the wind is howling onshore. This is big, messy, and for the experts only, and even then, it's a battle. The setup looks more interesting for kite surfing than paddle surfing during that windy spell.

The second week starts with a massive pulse. Sunday the 9th of August has a 13ft SW swell with a strong cross-onshore wind. Monday the 10th is the biggest day of the whole run, with a 15ft SW swell, a 19-second period, and massive wave energy (14051). The wind is a cross-shore, so it's not completely blown out, but it's a serious, heavy, expert-only wave. The period is so long it might be breaking a bit straight at the beach, but for a river mouth, it could be holding some good lines.

The swell drops back through the middle of the week, but looks to stay clean. Wednesday the 13th of August is a real highlight. The morning offers a 12ft WSW swell with a 14-second period, and crucially, a light cross-off breeze from the SE. That's a recipe for excellent, clean conditions for experienced surfers. The energy is very strong (4610). That morning session is the one to plan for.

All in all, a classic winter run. A few early windows of clean, fun waves, and a couple of huge, powerful swells for the experienced crew. The 10th of August and the 13th of August are the real standouts.

Rusty.
