Righto, grab a seat. Rusty here, and I gotta be straight with you – the next couple of weeks at Rivermouth Wailuku are looking pretty grim for paddle surfing. There's no good surf on offer right now, and you're looking at a solid 16-day stretch where conditions just don't line up.
We kick off Friday, July 3rd, with a 5ft ENE swell pushing in, but it’s got a short, weak period of just 8 seconds. That’s lethargic, junky energy, and combined with a persistent cross-onshore wind, it's churned up and messy. The water temp is sitting at a warm 79°F with an anomaly of 0.7°F, so nothing unusual there, just your typical tropical bath. The wind stays cross-on from the east-northeast all through the first week, gusting to 16 mph at times, keeping the surface chopped and the wave quality poor. The combined swell energy barely cracks 300 (269-370) for most of that run – that's weak to moderate at best, and definitely not enough to overcome the onshore breeze.
The second week isn't any better. The swell drops off a bit, slipping down to 4ft to 5ft, and the period gets even shorter, dropping to 6 or 7 seconds. Combined energy dips down to the 150-250 range – that’s weak. This spot is a reef break that’s exposed, but it needs a clean window. We’re not getting one. The setup here, with persistent cross-onshore wind and short, weak swell, honestly looks more interesting for kite surfing than for a paddle session.
There are no true standouts in this 16-day window. The closest we get to a maybe is Monday afternoon, July 13th, when the wind eases to just 6 mph from the ENE, and the swell bumps up to 5ft. That’s the only time you’ll see a "marginal" tag, and even then, it’s still cross-onshore. For the rest, it’s a blank run. This spot is "fairly consistent" so it tends not to stay this poor for long, but for now, leave the board at home.
Rusty.
