The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Slade Bay/Boot Reef. This is a reef break, SW is the optimum direction, and it gets a fair bit of swell. But I gotta be straight with you – the next two weeks are a real mixed bag.
The overall pattern is a whole lot of onshore, cross-shore, or just plain messy wind, which is kryptonite for a reef like this. We’ve got a long gap of poor conditions right from the start. The first real chance to get wet doesn’t appear until the morning of Thursday the 13th, and even then it’s only just surfable.
Thursday morning, August 13th, is about as good as it gets for the first week. We’ve got a clean, 3ft swell rolling in from the WSW with a period of 10 seconds, and light WNW cross-offshore winds. The wave energy is moderate (184). It’s not going to be pumping, but it will be rideable and clean.
The rest of the first week and into the second is a write-off. Friday morning the 14th is clean but small at 2.5ft, and then the wind gets messy. The long-period, 18-second swell that shows up Monday afternoon, August 17th, is a real tease – it’s only 0.3ft, so you’d be floating over nothing. By Tuesday the 18th, we get a bump in size to 4ft to 4.5ft, but it’s a short-period 6-second wind swell straight onshore from the SW. That’s a recipe for a choppy, sloppy mess.
The second week offers a few more clean windows, but the quality isn't there. The morning of Thursday, August 21st, is clean with a 2.5ft WSW swell, but the energy is weak (104). The morning of Saturday, August 23rd, is glassy with a 1.5ft swell, but again, that’s tiny. Then on Sunday, August 24th, we see a big jump in energy – 504 on the scale – with a 5ft swell from the W, but it’s cross-onshore with fresh winds, so it’s blown out and choppy. That’s a kite-surfing setup, not a paddle-surfing one.
The best and only true standout here is Thursday morning, August 13th. It’s the cleanest, most surfable wave in the whole forecast. The rest is either too small, too windy, or too messy to bother with. This spot can be *sometimes* crowded, but on a Thursday morning with mediocre waves, you’ll likely have it to yourself.
