Aha Rivermouth Surf Forecast and Surf Report

Alright, Rusty here. Let’s break it down for this spot. The first week or so is a total dud – flat and frustrating. There’s a real spike of swell in the second week, but the size and conditions are all over the place.

Right now, through to the end of July and into early August, the surf is tiny. We’re talking 1ft to 2ft waves from the east and southeast with weak energy. The wind is mostly cross or onshore, and the conditions are poor. Aha Rivermouth is a beach/jetty setup, and with this little push and messy wind, it’s just a flat paddle. It’s a long, boring stretch of nothing.

Then, around the 3rd of August, things get interesting. On Monday the 3rd, we get a solid 2ft to 2ft groundswell from the east with a period of 12 to 13 seconds. The energy jumps up. The wind is light onshore, but it’s still a bit marginal. The real action starts Tuesday the 4th. That’s when a proper swell arrives. The forecast shows 5ft to 6ft from the east with a very long period of 16 to 17 seconds – that’s serious groundswell energy. The wind is light and cross-shore, which will keep it reasonably clean. This is a standout for competent surfers. The long period means better shaped waves, and the cross-shore will help hold the line. This will be a proper session.

By Wednesday the 5th, the swell jumps to 8ft to 8ft from the east with an 18-second period. That’s a lot of power, but the wind turns cross-onshore, so it’ll be a bit lumpy. This is getting into the range where it’s too big for beginners and only good for experts. The beach/jetty setup might get a bit messy.

Thursday the 6th is the big one. The swell is peaking at 10ft from the east-northeast with a 17 to 18-second period. The energy is massive. The forecast directly says it’s too big for this break. This is expert-only territory, and even then, it might be a washing machine. The wind is light onshore, so it’s not ideal, but the sheer size will be a sight. This is not a day for the faint of heart.

Friday the 7th is a much better proposition. The swell drops to 4ft from the east-northeast, still with a nice 14-second period. The wind goes glassy in the morning, which is a major positive. Expect very clean conditions with that long-period groundswell. This is the best of the lot for the whole outlook – decent size, long period, and offshore winds. If you can only make one day, this Friday morning is the one.

The weekend after that, the 8th and 9th, the swell mixes up. You get a weird northwest swell with a short 5-second period and some east-northeast energy. The wind goes cross-offshore, which is clean, but the wave quality is poor or ordinary. By Sunday the 9th, it’s back to tiny 1ft with rain and moderate wind.

So, the highlights: It’s a flat start, then a big pulse of groundswell mid-week. The standout is Friday the 7th morning at Aha Rivermouth, with 4ft of east-northeast groundswell, glassy conditions, and a long period. That’s the one to circle. Tuesday the 4th is also a good call for stronger surfers with that 5ft to 6ft groundswell and light cross-shore wind. The crowds at Aha Rivermouth can show up sometimes, but with the right timing, you’ll get a good one.

Stay stoked, and keep your eyes on the horizon.
