The Lowdown

G’day, Rusty here. Look, I’m not gonna sugarcoat it—this is a pretty flat stretch for Laniakea Reef and Holtons. The whole 16-day window is a bit of a struggle, with only a handful of moments that are even worth paddling out for. It’s not a total write-off, but you’ll be waiting for the small windows of clean, rideable waves.

We kick off Sunday the 13th with the best of a weak run. Morning sees a little 3ft swell out of the NNE, period around 9 seconds, with a light cross-off breeze from the ENE at 6 mph. The combined energy is moderate at 162. It’s clean, but it’s small and ordinary. The afternoon stays similar but the breeze picks up a touch to 9 mph, and the energy drops to 112. Not a standout, but it’s the best we’ve got early on. The water temp is about average for this time of year.

Monday the 14th drops off to 3ft, period down to 8 seconds, and energy falls to 87 in the morning and 80 in the afternoon. Still cross-off and clean, but it’s pretty weak.

Tuesday the 15th morning throws a bit of a curveball with a 2ft swell from the SW at a very long 20-second period. Energy jumps to 240. That’s a long-period groundswell, which can be tricky on a reef setup—might wrap in with some shape, but it’s small and the cross-off wind is 9 mph. The afternoon fades to 3ft from the NNE but with only 8 seconds and energy of 52. Not much to get excited about.

From Wednesday the 16th right through to Saturday the 26th, it’s mostly poor conditions day after day. Swells hover around 0.5ft to 3ft, with winds picking up to 16–22 mph out of the ENE and E. The energy is mostly in the double digits, with a few spikes around 150–168. There’s a long stretch here with nothing worth calling a session.

Finally, on Saturday the 26th afternoon, we see a return to surfable but ordinary waves—2ft from the SW, 15-second period, energy of 168, with a gentle breeze. Sunday the 27th morning is similar with 2ft from the NW, 16-second period, energy of 90. Clean, but tiny.

If I had to pick the best on offer, it’s Sunday the 13th morning—small, clean, and the most consistent energy in the whole run. The other little spike is Tuesday the 15th morning with that long-period SW groundswell, but it’s tiny. Don’t expect much else. The reef can hold a bit of shape on those long-period swells, but with the size this low, it’s more of a longboard glide than a proper session.

Stay patient, keep an eye on the forecasts—things can turn around.

Rusty.
