The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Whitesand Bay over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s gonna be a long wait for anything worth paddling out for. The first week and a half is pretty much a write-off. We’re looking at a stretch of tiny, weak swells and poor conditions from Monday the 10th all the way through to the 20th. You’ll see a bunch of mornings with clean-looking water but barely a ripple, with heights struggling to hit 3 ft and combined energy levels mostly under 200 (that’s weak). The winds are mostly cross-off or light, but there’s just no power in the ocean. It’s a real flat spell for the beginners out there, but honestly, for anyone, it’s a no-go.
Now, hang in there, because things finally start to look up around Friday the 21st. The morning shows a bit of hope – a glassy 3 ft swell from the west, but the period is a short 5 seconds, so it’s not going to be doing much. The energy is still weak at 82. Still, that glassy surface is a treat. But don’t get too excited, because the afternoon brings a messy 5 ft onshore bump.
The real standout window is the weekend of the 22nd and 23rd. Saturday the 22nd sees a big jump in size – 10 ft from the west in the morning, and a massive combined energy of 865 (strong). That’s expert territory, though. The wind is a moderate cross-shore, so it’ll be a bit lumpy. The afternoon drops to 8 ft, still hefty.
But the pick of the whole forecast is Sunday morning, the 23rd of August. We’ve got a clean 7 ft swell from the northwest, with a light cross-offshore breeze. The combined energy is 493 (moderate to strong). This is the one. For experienced surfers, that’s a proper session. The swell direction matches the optimum (WSW) really well, so expect some decent shape. Just be aware, at 7 ft, it’s going to be a handful for the beginners. Crowds are sometimes an issue here, so get in early.
The following Monday morning, the 24th, is glassy but tiny at 1 ft with a very long 14-second period, but that long period on a beach break like this can make it close out. Not the one.
So, to sum it up: a long, flat first week and a half, then a massive peak on Sunday the 23rd. That’s your best bet. Keep an eye on the forecasts, but right now, that Sunday morning is the one to circle on the calendar.
Rusty.
