Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a tough run ahead. We’re looking at Rivermouth_Wailuku, and honestly, the whole 16-day window is one long, flat, choppy mess. There’s not a single decent session in the mix. The first few days of July kick off with a 6ft to 6ft ENE swell, but the wind is a solid cross-on from the ENE at 12–16 mph, which is just tearing the surface apart. The water temp is sitting at 80°F, which is bang on average for this time of year, so at least you won’t be cold while you’re getting frustrated.
The combined wave energy bounces around between 286 and 447 (moderate energy), but it doesn’t matter because the quality is shot. The period is short too – mostly 7 to 8 seconds – so it’s just weak, bumpy, unsurfable lines. That persistent ENE cross-on wind is the main culprit, and it doesn’t let up at all. Even on the 14th and 15th of July, when the wind drops to a gentle 9 mph, it’s still cross-on and the swell drops to 4ft to 4ft. It’s just not happening.
The only highlight I can even mention is that around the 18th and 19th of July, the period stretches out to 9 seconds, which is slightly better, but the swell is still small (4ft) and the wind is still messing it up. It’s a ‘poor surf conditions’ label on every single time slot, and I’m not gonna sugarcoat it – there’s nothing to get excited about here.
If you’re a kitesurfer, this setup might actually be worth a look, because the consistent cross-on wind and moderate swell energy could get you planing. But for paddle surfing? Put the board away for a bit. The break is fairly consistent, so it’s a bit of a shock to see such a blank run, but forecasts can change. For now, though, it’s a solid no-go.
Rusty, signing off.
