The Lowdown
Alright, Rusty here again. Let’s break it down in feet.
Look, the surf window is real tight. Only one spot, Laniakea Reef and Holtons, shows up, and it’s a consistent reef break that needs a NW swell. For the first week, it’s tiny.
Sunday, August 16, we’ve got a 1ft WNW swell with a 12-second period, combined energy a weak 35. Wind is a strong 25 mph cross-off from the ESE, so it’s clean but bumpy. The whole stretch up to August 20th is poor – nothing worth paddling for.
There’s a little bump around Wednesday, August 19th, a 2ft NE swell, but the period is only 6-7 seconds, and combined energy is 113 – moderate. Winds are light, 9 mph cross-off from the east. It’s surfable but very ordinary.
Friday, August 21st is your best shot. Swell hits 3ft from the NE, still short-period at 7 seconds, but combined energy sits around 107. Winds are light, 6 mph from the east, cross-off and clean. The waves will be small and weak, but it’s the biggest we get in the first week. Not a standout, just the least bad.
Then from Saturday, August 22, it dies completely – flat or near-flat for over a week. The next flicker shows up on August 31 with a 2ft W swell, 16-second period, combined energy 131. Still poor surf conditions, with a 16 mph ENE cross-off.
No real standout. If you’ve gotta go, shoot for Friday the 21st. The rest is a long, flat wait. Crowds can be expected at Laniakea when there’s anything at all.
Rusty.
