The Lowdown
Alright, let's not sugarcoat it. The next week and a half is looking flat and frustrating at Slade Bay/Boot Reef. The swell is just about non-existent, with energy readings down in the single digits and low teens for days. You're looking at ankle-biters and nothing with any push.
There is one tiny window that might get your heart rate up. On Thursday the 13th, the morning brings a pulse of energy, hitting 161 on the combined scale. Swell height is still small, around 3ft, but it's coming from the southwest with a 12-second period, and the wind is dead glassy. That's your best shot at a clean, surfable wave in this whole stretch. Being a reef, that longer period swell will have a bit more shape to it. It's not going to be epic, but it's the only real option on the table.
After that, it all fades back to nothing. Tiny waves, weak energy, and winds that keep shifting around. There's a small bump around the 22nd and 23rd, with the swell reading around 3-3ft, but the periods are short and the energy is weak. It'll be pretty gutless.
Bottom line, this is a lean period for Slade Bay/Boot Reef. No big swells on the cards, and consistency is a real issue. If you're keen for a paddle, your best bet is Thursday the 13th, but don't expect to be threading any barrels. Might be a good week to work on the tans.
