The Lowdown
Alright, this is Rusty, and I’m looking at the forecast for Slade Bay/Boot Reef. The water temp is coming in about average for this time of year, so nothing crazy there.
Let’s be real, the next week and a half is a grind. We’ve got a long stretch of poor conditions starting from Thursday the 27th of August. The wind is mostly cross or cross-on, and the swell is all over the place but messy. The combined energy is weak to moderate at best, hitting a low of 6 (21) on Thursday afternoon, then slowly building. The only real highlight in the first week is Wednesday the 2nd of September morning. That morning the wind goes glassy, with a 4ft swell from the WSW, but it’s a short period at 5 seconds, so it’s small and weak, just surfable, not special. The combined energy is only 98, so really weak.
From there, it’s back to poor surf until we hit a promising run. The standout is Monday the 7th of September. Both morning and afternoon at Slade Bay/Boot Reef look clean. The morning brings a 6ft swell from the west, period at 8 seconds, with a light cross-offshore breeze from the NNW. The combined energy is 403, which is solid moderate. The afternoon holds a 6ft swell from the west, period 7 seconds, with a light cross-offshore breeze from the NW. Combined energy at 303. This is the best window in the whole 16-day outlook. The swell direction is southwest, which matches the optimum swell direction for this reef break, and the wind is light and clean.
Then Tuesday the 8th still has clean conditions but the swell drops off fast to 4ft and 3ft, energy fading. After that, it’s mostly small and weak until Friday the 11th of September morning. That morning shows an 8ft west swell with a period of 8 seconds, and a light offshore breeze from the north. The combined energy jumps to 1009, which is strong. It’s an expert-only size, but it’s promising. The direction is west, and the optimum swell direction for this break is southwest, so it’s a bit off, but still good. Keep in mind, that’s a long way out, so forecasts could change.
Overall, the best bet is Monday the 7th of September. It’s the only window where everything comes together for a proper session. The rest of the time, you’re either fighting the wind or waiting on small, weak swell.
Rusty.
