The Lowdown
Alright folks, Rusty here with a look at the local stretch.
Right off the bat, the next week and a half is gonna be flat and frustrating. We’ve got a long dry spell staring at us, with next to nothing on offer from now until at least the 27th of September. For Laniakea Reef and Holtons, it’s all tiny, weak dribble with period so short the waves just collapse. The swell energy is in the single digits and low hundreds – nothing to get excited about. Add in a constant cross-off wind that’s howling at 16 mph and you’ve got blown-out, unrideable conditions.
Now, there is one flicker of hope right at the very end. We get a nice late-season long-period groundswell starting to show on Sunday the 27th. The combined energy jumps right up to 457, and you can feel it. The swell direction is from the NW, which isn't the absolute best for this spot – we’d prefer it straight out of the NW – but it’s close enough. The wind does settle a little by Monday the 29th, dropping to a manageable 9 mph, still cross-off but lighter. The waves will be around 3 ft with a long 12 second period, meaning cleaner, more lined-up sets and easier paddling. This reef set-up should handle it nicely.
The standout here is clearly Tuesday morning the 29th. It’s the last day of the run, the wind is the lightest, the conditions are noted as “expect good surf,” and we have that nice, clean long-period NW swell. It won’t be huge, but for the quality, it’s easily the best bet in the whole 16 days. Stick with the reef, don’t expect much until the very end, then make the most of that Tuesday dawn patrol.
Rusty.
