The Lowdown
Let’s have a look at the picture for Whitesand Bay, lads. Honestly, it’s been a proper flat spell for the near future, so don't rush to grab the boards just yet.
We’re looking at a long stretch of tiny, gutless surf kicking off for the next week or so. The first pulse that looks even worth a mention is on the morning of Thursday, August 27th. We’ll see some chest-high waves, around 4ft, pushing in from the SSW. The energy climbs a bit (384) and with a clean cross-off breeze, it'll be the cleanest you’ll see for a while, even if it’s just a marginal session.
After that, it gets a bit wild. Friday the 28th is blown out, and the weekend brings side-shore slop. There’s a bit more push on Saturday the 29th with waves around 3-4ft and some energy (485), but a cross-onshore wind will leave it choppy.
Now for the big call later on. On Wednesday, September 2nd, a serious, long-period groundswell from the southwest arrives. We’re talking double-overhead to well-overhead, with waves up to 10ft and the energy reading hitting a massive 2356. That’s proper power. But with that size, it's strictly for experienced surfers only. A moderate onshore wind is going to make it a messy, lumpy beast. The same story holds for Thursday the 3rd with 10ft waves and heavy rain.
So, realistically, this is a tough outlook for a break that normally sees a bit of action. The first week is a write-off. The only standout that makes the cut is the morning of August 27th, with those clean 4ft waves from the SSW. After that, the big September swell has power but the wind and size mean it will be a ruthless, choppy challenge. For the average surfer, there’s not a lot to get excited about.
