The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this stretch looks grim for paddle surfing. The entire 16-day window is a write-off for clean, surfable waves. We’ve got a solid run of cross-shore winds that just won’t quit, and the wave quality is shot through the whole period.
Looking at our only option here, Middles/Generals, the story is the same all the way through. From Tuesday 4th August to Wednesday 19th August, every single session is tagged with "poor surf conditions." The wind is relentless – a constant cross-shore breeze from the NE or ENE, mostly in the 15 mph to 25 mph range, sometimes stronger. That’s going to put a nasty cross-chop on the surface, making it a bumpy, frustrating mess. The water temperature is sitting around 80°F, which is pretty normal for this time of year.
The swell energy does build significantly. You’ll see the combined energy climb from moderate values early on, right up to very strong levels in the second week. But with that lumpy, messy wind, it’s all for nothing. The swell direction is mostly ENE, which is the optimum direction for this spot, but it doesn’t matter when the wind is ruining it. By the time we get to the 17th, 18th, and 19th of August, the swell is punching over 10 ft, and the energy is massive, but with a strong breeze onshore, it’s just a big, blown-out, dangerous mess. That’s expert-only territory, and even then, it won’t be any fun.
Honestly, with this persistent cross-shore wind and the beach setup, this whole forecast looks way more interesting for kite surfing than for a paddle surfer. There’s simply no standout session to recommend. A blank run like this can happen, but with the energy on offer, it’s a gut-wrencher.
Rusty.
