Aha Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming our way.

Right off the bat, we’ve got a whole lot of nothing for the first week or so. Aha Rivermouth is small and wonky from the 28th of July all the way through the 1st of August. We’re talking tiny 0.7ft to 1ft slop, with light cross-onshore winds messing things up. The combined energy is weak, and it’s just not worth paddling out for. You’d be better off staying on the beach.

Then, on the 2nd of August, there’s a hint of something. The afternoon swell pushes to 1ft but with a very long period of 16 seconds, and the energy bumps up a bit. It’s still cross-shore and pretty weak, but the glassy morning on the 29th of July was a tease – that 1ft with glassy conditions was clean, but just too small to do anything with.

The real story starts Monday, the 3rd of August. We get a proper jump in size. The morning sees 3ft swell from the east with a 14-second period, and the energy is moderate. By the afternoon, it’s up to 4ft with a 16-second period. Still, the wind is a moderate cross-shore, making it a bit bumpy, and the score is marginal. It’s not a standout, but it’s the first real sign of life.

Now, the big one. Tuesday, the 4th of August, is where things get serious, but not for the faint-hearted. The swell jumps to 5ft in the morning and 6ft in the afternoon, both from the east with a very long period of 18 seconds. The afternoon energy is strong. That’s a lot of water moving. But the wind is a moderate cross-onshore, so it’s chopped up and messy. This is too big for beginners and honestly, it’s not clean enough for experts either.

Wednesday, the 5th of August, is even bigger. 8ft from the east with a 19-second period, and energy is very strong. Still cross-onshore, still choppy. A real beast, but not a friendly one.

The best of the whole run, and I mean the absolute standout, is Thursday, the 6th of August. The swell is a solid 13ft from the east-northeast with a 19-second period. The energy is massive. That’s a groundswell of serious heft. For the morning, the wind is a moderate cross-shore, but by the afternoon it swings to a clean cross-offshore from the west-northwest at 22 mph. The wave comment says it’s too big for this break, and you know what? That’s just for the average surfer. For a top-tier expert, that afternoon session is pure magic. Glassy, clean, and a mountain of energy. If you’re a pro, you’re charging. If you’re not, stay far, far away.

Friday, the 7th of August, is still big. The morning has 12ft from the east-northeast with a 17-second period. The afternoon drops to 7ft with a 16-second period. Both sessions have clean, cross-offshore winds. The morning is still too big for most, but the afternoon is more manageable. Still, a marginal call.

Then we get a weird one. Saturday, the 8th of August. The swell is 10ft from the north with a 13-second period, and the energy is strong. The wind is glassy in the afternoon with a light offshore in the morning. It’s clean, but it’s a north swell, and the optimum direction for this break is from the northeast. It’s still too big for most, but the glassy conditions are a huge plus.

After that, it fades. Sunday, the 9th of August, sees 5ft dropping to 4ft from the north-northwest, with cross-onshore winds and gentle chop. Monday, the 10th, is back to small and messy, and by Tuesday and Wednesday, the 11th and 12th of August, it’s a complete write-off with storm-force winds on the 12th.

So, the bottom line: if you’re an expert, the afternoon of Thursday, the 6th of August, is your target. Thirteen-foot groundswell, clean offshore wind, and a lifetime of energy. For everyone else, it’s a long wait. The first week is a bust, and the second week is either too big or too messy. The best of the rest is probably the afternoon of the 7th with 7ft and clean wind, or the glassy morning of the 8th, but that’s still a big north swell. Keep an eye on it, but don’t get your hopes up.

Rusty.
