The Lowdown
G'day, I'm Rusty, and I've got a look at what's happening at Whitesand Bay. Let's be straight with you - this stretch of the next 16 days is a challenge. The forecast is showing a lot of poor conditions, with messy wind and just average surf. The water temperature is sitting at about 62°, which is pretty normal for this time of year, so the wetsuit will be fine.
The first real chance of anything decent doesn't kick off until Monday, September 7th. We've got a solid 7ft to 6ft swell from the WSW, but the wind is howling from the west at 22 mph and it's onshore. The swell period is a short 8 seconds, so it's not going to have much shape. The combined energy is moderate, sitting around 596. It's going to be a battle, and honestly, it's not a good setup for a paddle. This is a beach, and with that much wind and swell, it might be more interesting for the kite surfers than the paddle crew.
The real standout, and the only thing worth getting excited about, is the Monday morning of September 7th. The swell jumps to 6ft from the WSW, but the period is a very long 13 seconds - that's proper groundswell energy. The combined energy is strong, hitting 1179. The wind is offshore from the west at 16 mph, which is a huge positive. For a point break, this long period swell will wrap in nicely, and with offshore wind, it'll be clean. It's a bit of a beast at 6ft, so it's not for beginners, but for the experienced crew, this is the one. It's a Monday, so crowds are possible, but you might get a few good ones if you're early.
After that, conditions go back to being ordinary. The next few days, from Tuesday September 8th to Thursday September 10th, have a mix of 8ft to 7ft swell, but the wind is onshore and strong, and the period drops back to 8 seconds or less. The energy is moderate to strong (611 to 634), but the wind is ruining it. The long range forecast from Friday September 18th and Saturday September 19th shows a glimmer of hope - a 5ft to 4ft swell with clean offshore winds, but the period is short (5-6 seconds) and the energy is low. It's surfable, but nothing to write home about.
So, the best of the bunch is that Monday morning, September 7th. Get on it if you can, but don't expect a party.
Rusty.
