The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for this little corner of the world. We’re talkin’ about a spot that’s a real gem, but it’s not for the faint of heart. It’s a rare-breakin’ reef set-up, and the forecast shows we’ve got a bit of a wait before the real magic happens.
The first few days are pretty flat and ordinary. Tuesday the 4th is a write-off with a weak, short-period swell and a messy cross-shore wind. Wednesday the 5th has a tiny window of clean, glassy conditions in the morning on a 2ft swell, but the energy is weak (174). It’s surfable, but it’s not gonna get the heart pumpin’. The rest of the first week is a real struggle – onshore winds, small chop, and poor conditions. You’re better off waitin’ for the real deal.
Now, the first real standout we’re lookin’ at is Saturday the 15th. The morning session is the absolute pick of the whole run. We’ve got a clean 7ft swell from the SSE, with a long 13-second period. The combined energy is cookin’ at 1382 – that’s strong, powerful stuff. The wind is a light breeze, cross-offshore, which means the face will be smooth as glass. This is solid, expert-level groundswell. It’s gonna be a bit heavy, and with that long period, it’ll be faster and more powerful, which is perfect for this reef. The crowds are likely to be around, but for a wave this good, you’ll paddle out anyway.
The next big one is further out, on Tuesday the 18th. The morning shows a solid 8ft swell from the ENE, with a 9-second period and a massive 1975 combined energy. That’s a lot of power. The wind is light and cross-offshore, keepin’ it clean. It’s a bit of a shorter period, but the size and energy make up for it. This one is also for the experts only – it’s too big and powerful for the beginners. It’s a promising long-range call, but we’ll have to see how it shapes up.
The afternoon of the 15th is still a good option, with a 4ft clean swell, but it’s not the morning. The same goes for the 18th afternoon – 7ft and clean, but a step down from the morning peak.
Other than those two main highlights, most of the days are marginal or poor. The water temp is around 65°, which is about average for the time of year, so nothin’ to worry about there.
Rusty, out.
