The Lowdown
Alright, Rusty here. Let’s look at what’s happening for Cap St Louis.
To be straight with you, this is going to be a lean run. We’ve got a long stretch of tiny or messy surf before anything worth paddling out for shows up. From the 28th of August right through until the morning of the 3rd of September, it’s mostly small, weak, and just not doing much. The afternoon of the 2nd does see a jump in swell height to 6ft, but with a fresh cross-shore wind and lumpy chop, that one’s a write-off. You’re better off waiting.
The first real glimmer of hope comes Thursday morning, the 3rd of September. Cap St Louis (reef) should see a clean 5ft swell from the WNW, with a period of 6 seconds and moderate wave energy (273). The wind is a gentle cross-off from the NNW, so expect clean faces. It’s rated for advanced surfers only, and this spot is inconsistent, so don’t expect it to be firing every day. Still, this morning window is the standout of the first week. Crowds are likely here, so get in early.
After that, we drop right back down into tiny waves and mostly poor conditions until the morning of the 10th of September. That morning offers a glassy 4ft swell from the south, with a period of 7 seconds and moderate energy (158). The water temp is a touch warmer than normal at 75°, so it’s a bit unusual for the time of year. The conditions are glassy, which is a huge plus, but the surf is just ordinary – not terrible, but nothing to write home about.
Then, the best bet of the whole outlook lands on Friday morning, the 11th of September. Cap St Louis picks up a clean 7ft swell from the WNW, period of 6 seconds, and strong wave energy (297). The wind is a gentle cross-off from the NW, so it should be clean and lined up. This is for experts only – at 7ft it’s big, powerful, and not for the faint-hearted. Given the spot is inconsistent and exposed to the SW, the direction is good for this break. Crowds are likely again, but for a morning like that, you won’t mind sharing.
That Friday morning is the real highlight. After that, the swell drops off fast into the weekend.
Rusty.
