The Lowdown
Alright, folks, Rusty here again, but this time in the old units. I’ve had a look at the local charts, and I’m telling you, it’s a total bust. There’s not a single decent wave in the whole 16-day outlook. The first record is on Wednesday, 12 August, and it’s flat, and it stays flat right through to Thursday, 27 August.
The only spot we’ve got to talk about is Laniakea Reef and Holtons. It’s a consistent reef break, exposed to the swell, but it’s getting nothing. The water temp is 80°F with a 0.4°F anomaly, so it’s pretty average for the time of year.
The whole period is a write-off. Cross-off winds from the east and east-northeast, blowing 12 mph to 31 mph, are going to mess up the surface. The swell heights are tiny – 0.7 ft to 1 ft, with one tiny spike to 3 ft on the afternoon of Wednesday, 19 August. But that little pulse has a period of just 6 seconds, so it’s weak and messy. The combined swell energy is pathetic, with the highest reading a lousy 83 (weak energy) on the 19th. The swell direction is all over the shop – WNW, NNW, W – none of it matching the sweet spot for this break, which is NW.
The wind gets a bit nasty on Saturday, 15 August, with a strong breeze at 25 mph and rain showers, and by Sunday, 16 August, we’re looking at a near gale at 31 mph with a risk of thunderstorms. That’s not surfable, that’s a day for the pub.
Honestly, this is a classic dry spell for this area. For a spot that’s usually reliable, this is a real bummer. The setup is more interesting for kite surfing than paddle surfing, given the constant wind and complete lack of rideable swell. But don’t give up – it never stays this poor for long, and forecasts can change. Keep an eye on it, but for now, the boards can stay in the shed.
Rusty.
