The Lowdown
G’day, it’s Rusty.
We’ve got a bit of a slow start here for Laniakea Reef and Holtons. The first couple of days are pretty flat and not worth getting excited about. We’re looking at tiny, weak surf with a lot of cross-off wind, so don’t bother paddling out until things change. It’s a classic case of the ocean taking a breath.
Water temp is sitting at a normal 80°, so no worries there once you’re in.
The first real pulse of energy shows up on the morning of the 8th. We’ve got a jump to 8ft of swell from the WSW, with a 10-second period. That’s a decent wave, but the wind is a cross-off at 19 mph, which will make it a bit lumpy and tricky to manage. It’s a marginal call at best and probably more of a handful than a treat.
After that, it backs right off again. The 9th and 10th are pretty underwhelming, with small, weak surf and not much behind it. We go through a bit of a flat spell where the waves are just dribbling and not worth the paddle. The 11th, 12th, and 13th are much the same – ordinary, small conditions. There’s some energy around on the 12th morning, but the swell direction is all over the place and the size is tiny. You’d be better off doing something else.
Things start to look a bit more interesting from the 16th. A long-period groundswell (18 seconds) from the SW shows up, pushing the energy numbers up. It’s still small, around 2ft, but that long period means there’s some push and shape to it. The afternoon looks glassy and the wind is light, so if you’re desperate for a wave, that’s your moment to get a few clean ones on a longboard.
But the real standout, the one to circle on the calendar, is the morning of the 17th. That’s when the swell from the NNW kicks in with a 13-second period and the energy is pumping. The surf builds to 5ft by the afternoon, and with the wind easing right off, it’s going to be clean and powerful. This is the best window of the whole stretch for Laniakea. The direction matches the optimum, the period is long enough for proper groundswell, and the conditions are looking good.
The 18th keeps that NNW swell running, with solid 5ft surf and a 12-second period. It’s still good, very good, but the morning will be the pick. The wind is light and offshore, so it should be lined up and hollow. This is the other window you don’t want to miss.
After that, it starts to taper off. The 19th is back to small, ordinary surf. But hold on, the 20th sees a bit more size return with 4ft, and the 21st and 22nd keep the NNW/NW flow going with clean conditions. The 22nd morning looks special – glassy conditions and 4ft of clean swell. That’s a perfect morning for a quiet session.
So, to be honest, the best on offer is the 17th and 18th. That’s when the north-west swell lines up with the wind and this reef will be doing its thing. It’s going to be worth the wait.
The rest is just keeping the board waxed and the eye on the horizon. It’s been a slow spell, but it never stays flat here for long.
Rusty.
