The Lowdown
Hey, Rusty here again. Let’s talk about Laniakea Reef and Holtons in feet and miles per hour.
Alright, so the first week and a half is basically a ghost town. Nothing but ankle-snappers and flat spells from the end of August right through the start of September. Water temp is about 81°, nothing surprising for the season.
Finally, on Thursday, September 10th, we get a pulse. Swell comes in from the NNE at about 4ft, with a 9-second period and combined energy around 305. That's moderate juice. The wind is a clean cross-off from the east at 12 mph. It’s rated as marginal, but it’s the first real sign of life.
The standout window looks like Friday, September 11th. The afternoon shows a NE swell pushing 6ft with a 10-second period and the combined energy jumps way up to 606. That’s strong energy. The wind stays clean and cross-off from the south at 15 mph. 6ft is getting into the range where beginners might want to sit it out, but for the rest of us, this is the session to aim for. The swell angle isn’t perfect for the break, but with that much power and clean conditions, you’ll find waves.
Saturday the 12th keeps the size around 6ft from the NE, although the period drops to 8 seconds. The combined energy is still a solid 408, and the wind stays light and cross-off from the south-southwest. It’s still a marginal read, but it’s head-high and clean.
So the real story here is the flat start, then a late burst of chest-to-head-high waves with clean wind on the 11th and 12th. That’s your best bet.
Rusty, out.
