The Lowdown
Right, let’s have a look at what Slade Bay/Boot Reef has on the cards for the next couple of weeks.
The honest truth is, if you’re hanging out for a proper session, you’re going to be doing a lot of waiting. The first few days are pretty grim, with tiny, weak surf and cross-shore winds making a mess of things.
The only real highlight in the whole run is the window that kicks off on Monday the 7th. We’ve got a solid pulse of west-southwest swell that jumps up to 6ft-7ft. Now, before you get too excited, the wind is howling from the west at 18-19 mph, so it’s going to be lumpy and cross. That combined energy is reading at a strong 1275-1590, and the period is a nice long 13 seconds, so there’s proper groundswell power in the water. This wave is going to be breaking as a raw, powerful reef slab – this is not one for beginners at that size. It’s an expert-only wave with that much push and a fresh cross-onshore breeze. We’ll see it drop back down as the week goes on.
After that, it's a slow fade. There’s a small, clean window Thursday the 9th in the morning with some cross-offshore wind, but the swell has dropped right back to 4ft and the period is short (7 seconds), so the energy is weak (130).
After that, it’s a long, drawn-out goodbye. The swell just keeps fading, and we see a whole run of days with practically nothing on offer. The water’s way warmer than usual for the start of September – about 6° warmer, which is a bit of a shock, but it doesn’t help the surf.
There’s one last flicker of life that’s just for the connoisseurs of small, clean waves. On the 19th and 20th, the ocean goes almost glassy with a tiny, long-period groundswell on the way, but it’s only 0.3ft, so it’s barely breaking. The energy is weak as can be. You'd be surfing ankle-biters. For this break, it’s a long spell of nothing.
So, in short: if you're skilled, keep an eye on Monday the 7th for the only real push. For the rest of the window, it’s a board in the car just in case, and a lot of patience. This is one of those times where the ocean just isn't cooperating.
