The Lowdown

Alright folks, Rusty here. Let’s be straight with you. Looking at the next couple of weeks, it’s a bit of a flat spell for the most part. We’ve got a long stretch of small, weak surf, and honestly, there’s no real stand-out day where everything lines up for a proper session. It’s a waiting game, and I’d say things look pretty quiet until we get well into the following week.

We do have a couple of pulses of more meaningful swell, but the wind is just going to be a pain. Early on, and I mean the first few days, it’s tiny. We’re talking knee-to-waist high dribble at best. There’s a little bump of energy on Wednesday the 5th, with a swell around 6ft but with a short, weak 7-second period and a strong cross-onshore WNW wind at 18 mph. That’s a mess, honestly. The energy reading is only 388 (moderate), which tells you it’s not organized. It’s going to be lumpy and poor.

The next few days, Thursday the 6th through to Tuesday the 11th, are proper flat. We’re looking at surf under 2ft, with the combined energy dropping to double digits – 108, 54, 21, you get the picture. There’s a clean glassy morning on Friday the 7th, but nothing to ride. And again on Saturday morning the 8th, it’s clean with a light cross-offshore breeze, but the surf is just not there. It’s a tough stretch for surfing.

We start to see something slightly more interesting around Wednesday the 12th of August. The swell builds a little, to around 3ft, and the energy picks up to 167 (moderate), but the period is still short at 9 seconds. The wind is onshore and building through the day, so it’s not going to be good. The swell keeps coming up on Thursday the 13th, hitting 5ft to 6ft, with energy right up there at 430 (strong). But the period is still short at 8-9 seconds, and we’re dealing with a solid onshore wind. It’s going to be lumpy, messy and blown out.

Then there’s a bit of a drop again, before a bigger pulse arrives on Sunday the 16th of August. We’re looking at a 7ft swell, with energy reading 516 (strong). This is the biggest of the window. But, and it’s a big but, the period is still just 7-8 seconds, and the wind is going to be howling from the NNW at 18 mph in the morning. That’s a recipe for a complete closeout at a beach break. Onshore wind and short-period swell just don’t mix. The afternoon calms down a touch to a 9 mph NW breeze, but the damage is done. This one’s for the experts, and even then, it’s likely to be a washing machine.

After that, the energy fades out again. We’ve got some cross-offshore winds late on the 15th and 17th, which sounds nice, but the swell is small and weak. The last few days of the window just die out completely, with strong onshore winds and minimal surf.

So, what’s the call? There really isn’t one. No break gets a mention as a highlight because it’s just all poor. The water is a touch warmer than normal at 65°, which is a nice touch for your first duck dive, if you can find a wave to duck dive on. This is the kind of run where you’d be better off checking the kitesurfing spots, because there’s plenty of wind and more than a bit of swell at times, but it’s not for the paddle crew. It’s a blank run, and it can happen here. Forecasts can change, but as it stands, I’d give this one a miss. It’ll turn around eventually, it always does.

Rusty, out.
