The Lowdown
Alright, this is Rusty, and I’m looking at the 16-day picture for Slade Bay/Boot Reef… and honestly, it’s a tough stretch. We’ve got a real quiet start, with no real surf to speak of for a solid week. From Thursday the 6th through Wednesday the 12th, it’s all tiny swell and pretty ordinary conditions—most of it is barely a ripple and not worth paddling out for.
The first real glimmer of hope comes on Thursday morning, the 13th of August. We finally see a pulse of waist-high swell, around 3ft, coming out of the WSW. The period is a decent 10 seconds, and the combined energy hits 193 (moderate wave energy). The kicker? It’s glassy. A light SSW wind of 3 mph, dead calm, clean conditions. Thursday afternoon stays clean too, with a cross-off breeze and a 3ft WSW swell. This is the best window we’ve got. Slade Bay/Boot Reef is a reef break, fairly exposed to a SW swell, and with light offshore winds, it’ll be your best bet. Expect it to be a bit inconsistent, but when the sets come through, they’ll have shape. It’s not a beginner wave at this size, but solid for intermediates.
The water temp is about average for the time of year, nothing unusual. Crowds are likely here, it can get busy, but with the rest of the forecast being so weak, you might have more room than usual.
Then we hit a bit of a blip. Friday the 14th and Saturday the 15th see a drop in quality. The swell is smaller, and the wind gets messy again. Saturday morning, the 15th, has a clean 2ft swell with some energy (176, moderate), but it’s short-lived. By afternoon, the wind picks up and the wave quality tanks.
After that, it’s a slow fade. There’s a brief window on Monday morning, the 17th, with a clean offshore flow from the north, but the swell is only 2ft. Not enough to get excited about. The rest of the second week is just small, choppy, and mostly cross-shore wind. Not a stand-out in sight.
So, to sum it up: if you want a wave, your best chance is the 13th of August—Thursday morning, glassy conditions, 3ft WSW swell. After that, it’s a waiting game. The surf might pop up, but it’s all a long shot.
Rusty.
