The Lowdown
Alright folks, it’s Rusty here. Let’s have a look at what’s coming our way. I’ll be straight with you: this stretch is a long, flat lull with only one tiny window that might get the heart beating, but we gotta wade through a lot of nothing to get there.
The next week or so is honestly a bit of a washout. From the 17th right through to the 27th, we’re stuck with tiny, weak swell and mostly onshore or cross-shore wind. The water temp at Fortunes Rocks Beach is running about 66° at the start, which is about normal for this time of year, but it won’t matter much because there’s barely a wave to ride. We’ve got a solid 11-day gap of poor surf, with most days showing combined wave energy barely cracking 50 to 90 (weak energy). The swell is short-period, under 8 seconds, and the wind is never doing us any favors. It’s a frustrating stretch for a surfer.
Now, keep your eyes on Friday, the 28th of August. That’s the one that stands out. It’s not perfect, but it’s the best we’ve got. The morning shows a clean 7ft swell coming from the SE with cross-offshore wind from the NNE at 12 mph. That’s a clean look. The combined energy jumps to 752 (moderate to strong energy), which is a real kick compared to the rest. This is solidly in the intermediate to expert zone at that size, so beginners should sit this one out. The period is short at 7 seconds, so it’s windswell, not groundswell, meaning it’ll be a bit lumpy and won’t have the long lines of a proper groundswell. It’s a sandbar setup here at Fortunes Rocks Beach, and with that short-period SE swell, it could be a bit sectiony, but the clean wind will make it rideable. The crowd factor reads “sometimes,” so you might have company, but it won’t be a zoo.
The afternoon of the 28th drops off to 4ft and gets a bit cross-chop, so the morning is the window. After that, we’re back into the small stuff through the end of the month and into September, with weak energy and clean but tiny waves.
So, the call is: wait it out. The 28th of August morning is your best bet, but don’t expect magic. It’s a brief pulse of clean, solid-sized swell in a very quiet stretch. For the rest, it’s a good time to wax your board and wait for a change.
Rusty.
