The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Laniakea Reef and Holtons.
Right off the bat, the next week or so is looking pretty flat and grim. We’ve got a long stretch of nothing, or next to nothing, until we see a real pulse of energy. That north-west swell window is what we’re after, and this spot needs the right direction to work.
We kick off Wednesday morning, the 2nd of September, with showers and a 15 mph cross-off Easterly. Nothing doing in the water, just a big zero for surf. This dead pattern hangs around for days. We get a tiny 0.3 ft SW swell on Friday the 4th, but it’s a 12-second period with hardly any energy (6), and the wind is still a fresh 19 mph cross-off. It’s a waste of time. Saturday the 5th sees a 1 ft NNE pulse, but again, weak energy (34) and 15 mph winds. Same old story through the weekend and into Monday.
Then things get interesting. On Monday afternoon, the 7th, a solid 4 ft SW swell shows up with a 14-second period. The energy jumps to a moderate 648, and we get 15 mph cross-off winds. It’s still only marginal due to tide, but it’s the biggest we’ve seen. Tuesday the 8th is the real standout here. We’re looking at a 8 ft SW groundswell with a long 16-second period, and the energy is a very hefty 3482. The wind goes offshore from the SSE at 25 mph, which is strong, but offshore. This is big, clean, and powerful. That 10 ft in the afternoon is pumping, but that’s expert territory. The 14-second period will see it wrap in and offer some good shape at the reef, so it’s not just for closeouts, but definitely not for beginners.
After that pulse, it fades fast. Wednesday the 9th is down to a 3 ft W windswell with short 8-second period and light ESE winds. It’s surfable, but average. We then hit another flat spell from Thursday the 10th right through to Sunday the 13th, with nothing but tiny 1.0 ft to 1 ft leftover pulses. The wind goes glassy a few times, but there’s just no water moving.
The second week offers some hope but it’s a longer-term look. On Tuesday the 15th of September, a 2 ft SW groundswell arrives with a very long 21-second period and energy of 413. The morning is glassy calm, and the afternoon is still clean with light cross-off. It’s labelled as good conditions, so expect clean little peelers. That 21-second period is prime for a reef like this, giving long, walled-up lines. Promising. Wednesday the 16th brings a 4 ft NE swell with a 9-second period and moderate energy (172). It’s surfable and clean, but nothing compared to the big Tuesday from the first week.
Best on offer: There’s one true standout in this 16-day window. Tuesday the 8th of September is the day. You get a 8 ft to 10 ft SW groundswell, long 14 to 16-second period, and strong offshore SSE wind. The combined energy of all swells here hits 3482 in the morning and 3675 in the afternoon. That’s very strong. The water temp is a normal 81° for this time of year, anomaly of only 0.2°. The crowds here are listed as “sometimes” busy, so with conditions like that, expect the lineup to fill up quick. If you’re a confident surfer on a proper gun, that’s your window.
Overall, a long flat start, one solid expert-level pulse, then a week of tiny clean leftovers.
Rusty.
