The Lowdown

Alright, folks, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty grim for a proper paddle. We’ve got a long stretch of small, weak, and messy conditions ahead, so if you’re itching for a wave, you might want to find something else to do for a while.

The good news is that the water temp is sitting at about 63°, which is just a touch warmer than average for this time of year. Not a big deal, but it’s something.

Right now, we’re looking at a blank period. From Friday the 14th all the way through to the 26th of August, it's basically gonna be clean but tiny, or bumpy and small. We’re talking ankle-biters and knee-high slop. The wind is all over the place, mostly onshore or cross-shore, and any swell that does show up is weak and short-period. The energy is just pathetic—we’re seeing values in the 15 to 170 range, which is nothing to get excited about.

We’ll see a little bump in energy around Tuesday the 18th (125) and Wednesday the 19th (172), but it’s still only 4ft to 5ft of wind-slop. Not worth the drive. By the 20th, it drops right back down.

There’s a window on the 22nd and 23rd where we get some longer period swell (15 seconds) coming from the southwest, and the wind turns offshore (cross-off from the NE). But, the size is still tiny—1ft to 3ft. It’ll be clean and glassy, but you’ll be doing more floating than surfing. It’s a bit of a tease.

Then, to close out the first week, the 27th of August sees a bit more size, with 5ft to 6ft on Thursday, but the wind is messy and the period is only 6 seconds. It’ll be lumpy and cross-chop, and probably not much fun. The energy is moderate (192 to 205), but it’s just not clean.

Now, here’s the one bright spot in the whole 16-day window. It’s a long way off, but mark your calendars for Friday, August 28th. The models are hinting at a proper pulse. We’re talking a solid 16ft of west-southwest swell with a 12-second period, and the wind is forecast to be cross-offshore in the morning. The guidance even flags it as wind and tide favorable.

But here’s the catch—it's predicted to be too big for Whitesand Bay. The energy reading is off the charts at 6934. That’s seriously strong. This isn't a beginner wave; this is big, powerful, and potentially dangerous. If you’re not an expert, stay on the beach. Even for the pros, this will be a handful. By Saturday the 29th, it settles a bit but is still 13ft to 12ft, which is still huge.

So, the story is: a long, flat, frustrating start, followed by a massive, potentially unrideable swell at the very end. The only real standout, if you've got the skills and the nerve, is that Friday the 28th. But it’s a long-range call, so don’t book your flights just yet. Keep an eye on it, and don't get your hopes up for the next week and a half.

Stay stoked, but stay patient.

Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Whitesand Bay may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
