The Lowdown
Alright folks, Rusty here. Let's be straight up about the next couple of weeks at Laniakea Reef and Holtons. It's looking like a pretty quiet stretch, to be honest. We’ve got a long gap of small, poor-quality surf to start, before a brief window of cleaner, more organized conditions shows up about a week and a half away. Don't get your hopes up for any massive days, but there's a couple of mornings worth keeping an eye on.
For the next week or so, starting Friday the 11th, it's mostly a write-off. We're looking at tiny swell, mostly around 1 ft to 3 ft from the north-northeast, with a cross-off wind that's not ideal. The wave energy is weak to moderate (between 25 and 163). The vibe is "poor surf conditions" for the vast majority of that time, with only a couple of mornings on the 12th and 13th being described as "surfable but very ordinary". Basically, a lot of waiting. The water temp is about average for this time of year, nothing out of the ordinary.
We do get a little spike in energy on the morning of Tuesday the 15th of September, with a 2 ft south-west swell showing up with a very long 20-second period and moderate energy (282). That's a nice, clean groundswell pulse. That long period suggests some real shape, but it'll be breaking pretty straight on this beach-and-reef setup, so don't expect it to wrap in perfectly. The wind is a cross-off from the east at 9 mph, which is okay but not perfect for that spot. It’s marked as “marginal surf forecast”, so it’s a maybe, not a guarantee.
But the real standout, the only one worth circling on the calendar, is Wednesday the 23rd of September. Both the morning and afternoon sessions are looking like a classic North Shore day. We've got glassy conditions with zero wind, and a clean 2 ft to 3 ft swell rolling in from the north-northwest with a nice 12-second period. The combined wave energy is moderate (100 in the morning, 160 in the afternoon). This is the best bet for a clean, fun session on a longboard or a fish. The glass makes it all worth it.
After that, it gets a bit rough again with stormy conditions and onshore wind on the 24th and 25th, so don't sleep on that 23rd window.
So, here’s the call: Don't bother with the first week. Maybe peek at that Tuesday morning the 15th for the novelty of the long-period south swell. But the one true standout is Wednesday the 23rd of September. Get out there for the glass, because that’s the best it’s gonna get.
Rusty.
