The Lowdown
Alright, Rusty here. Let's break down what's coming for the next couple of weeks.
To be honest, the first part of the outlook is a real bummer, a long stretch of flat, onshore junk. There's some bigger energy lining up later, but it's going to be messy.
We kick off on Friday, August 7th, at Honolii Beach Park (Big Island). The water temp is sitting at 27°, right around the average for the year. The swell is a weak 3ft from the NE, with a short period of 7 seconds, and combined energy is a measly 92. Wind is blowing onshore at 6 mph, making for poor, choppy conditions. Save your energy.
Saturday the 8th and Sunday the 9th don't get any better. We're looking at 3ft to 3ft of weak, short-period swell, with the wind shifting to a cross-onshore breeze. It's choppy and ugly.
Monday the 10th sees a little bump to 5ft from the E, with an 8-second period and energy climbing to 328. But the wind is still cross-onshore, keeping it ragged. The forecast says "poor surf conditions," and I'm not going to argue.
That poor pattern sticks around all week. The swell stays between 5ft and 6ft, but the wind is mostly onshore or cross-onshore, ruining any chance of a clean wave. It's a frustrating, grovelly stretch.
Then, on Friday, August 14th, things get a shot of adrenaline. The afternoon sees a big pulse: 8ft from the E at 11 seconds, with energy hitting a massive 2550. This is serious size for Honolii. But the wind is a cross-onshore 9 mph, and the forecast calls it "marginal." At 8ft, that's big for a river break, and with the wind, it'll be a messy, expert-only affair.
Saturday the 15th goes completely flat, zero energy.
Sunday the 16th brings another big pulse, 10ft from the ENE with a 9-second period and energy of 1403. Wind is light cross-onshore. Again, it's "marginal." For experts only, and the bumpy conditions won't help.
Monday the 17th morning is the biggest of the window, with 12ft from the ENE and energy topping 2296. But the onshore wind at 9 mph keeps it rough. The wave quality is going to be poor.
The rest of the window fades back into small, weak, and choppy surf.
So, the bottom line? There's no true standout here. The best on offer is the late-arriving big swell around August 14th and 16th, but it's raw, blown out, and for experts only. The setup at Honolii with that cross-onshore wind looks more fun for a kite surfer than a paddle surfer. It's a tough forecast.
Rusty.
