The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Laniakea Reef and Holtons.
We’re in for a pretty quiet start, I’m not gonna lie. The first week is mostly a write-off for any real surf. There’s a solid gap from Thursday the 3rd through to Monday the 7th where the swell is basically non-existent or just tiny, weak windswell. We’re talking about 5 or 6 days of flat to near-flat conditions. The combined energy is often in the single digits or low twenties during that stretch, so don’t even bother checking the cam.
We finally see a pulse of energy arrive on Tuesday the 8th. The morning brings a 4ft swell from the WNW with a period of 10 seconds, and the combined energy jumps to 456 (moderate wave energy). The wind is a light cross-off from the SSW, so the surface should be clean. It’s a bit of a messy, marginal swell for the tide, but it’s the first real sign of life. The afternoon sees the swell hold at 5ft from the WNW, but the period drops to 9 seconds, and the wind goes light cross-shore, which will put some tiny ripples on the face. Not the best, but it’s something.
Wednesday the 9th is a better bet. Morning offers a 4ft NW swell, 10-second period, with a clean cross-off breeze from the East. The combined energy sits at 240 (moderate). It’s not huge, but it’s clean and the reef will be working. This is a decent option for beginners and intermediates alike. The afternoon drops off a bit.
Now, the real standout is shaping up for late in the window. Thursday the 17th and Friday the 18th are looking like the best on offer. Thursday morning brings a 5ft NE swell with a 7-second period. The wind is light and offshore from the ENE, keeping it glassy. The combined energy is 215 (moderate). The peak of this run comes on Friday the 18th. The morning sees the swell building to 5ft from the NE, still a short 7-second period, but combined energy is a solid 418 (moderate). The wind stays light offshore from the East. This is punchy, clean, and will be fun for the better surfers. It’s a little too big for absolute beginners, but for anyone with a bit of experience, it’s the call. The afternoon holds similar size and conditions.
Water temp is sitting right around 80°F, which is bang on average for this time of year. No surprises there.
So, to sum it up: the first week is a dud, but the second week has some promise. Wednesday the 9th is a good warm-up, but the real highlight is Friday the 18th. That’s the morning to circle. The forecast is a bit further out, so it’s not locked in yet, but it’s got the best combination of swell, wind, and energy.
Rusty.
