The Lowdown
Alright, surfers, Rusty here. Let’s get into it.
The next couple of weeks are a real mixed bag. We’ve got a lot of energy in the water, but for the most part, the wind is going to be working against us. We're looking at a stretch where the conditions are just plain messy before things start to clean up and become more promising towards the back half of the window.
Right out of the gate, for Tuesday the 4th, we’ve got a big, powerful swell from the southeast pushing in. The energy is strong, with readings up to 5430. But that's paired with a cross-onshore wind that's going to churn things up into a choppy mess. Honestly, not worth your time unless you're a glutton for punishment. On Wednesday the 5th, there's a window early with glassy conditions and a solid 13ft of southeast swell, but the wave comment warns it’s just too big for this break, so it’s not happening here.
The rest of the week and into the weekend is a write-off. Lots of southeast and south swells, but we are looking at fresh to strong cross-onshore winds and lumpy, messy surf. Monday, August 12, is where things finally start to turn around. The swell is dropping to a more manageable 5ft for the morning, and the wind is coming from the west-northwest, giving us that cross-offshore flow. It’s going to be clean, and for a few hours there, it’ll be good for those who know what they’re doing.
Then, hold on to your boards, because on Sunday the 16th, there’s a real standout. It’s over a week and a half away, so take it with a grain of salt, but the potential is there. We’re looking at a morning with zero wind and glassy conditions, with a 8ft swell coming in from the east-southeast. The period is short, only 6 seconds, so it’s not going to have much punch, but the cleanliness and the wave state suggest "very good surf conditions." That’s the one I'd be pinning my hopes on if I want a day to myself.
Also keep an eye on Monday the 17th. The swell is still around 7ft from the ESE, and with a slight air, it’s going to be rideable, though the tide will be a factor. As we move into the following week, the swell fades and the wind shifts onshore, so it’s looking less and less interesting.
So, the short version: it's going to be a rough week. But next Sunday looks like the best chance for some quality, glassy waves at Akabane Long Beach. Fingers crossed that long-range forecast holds.
Rusty, signing off.
