Kua Bay Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s cookin’ at Kua Bay over the next couple of weeks. Gotta be honest with ya, the start is rough. Real rough. We’ve got a few days of flat or junk right out of the gate.

Right off the bat, Wednesday the 2nd and Thursday the 3rd are a write-off. Tiny little 0.7 ft dribbles with onshore wind on Wednesday... not worth getting the board wet. The water temp’s sitting at 82°, which is about what you’d expect for this time of year, so at least it’ll be a warm wait.

Friday the 4th, Saturday the 5th, and the morning of Sunday the 6th? Flat. Zero. Nada. The ocean’s takin’ a nap. That’s a solid three-day gap with nothing to ride.

Then Sunday afternoon the 6th, we finally see a pulse. It’s not magic – a 4 ft SW swell rollin’ in at 12 seconds, but with a cross-shore wind, it’s gonna be a bit jumbly. The energy’s moderate at 361. Still, it’s something to paddle for if you’re desperate.

Now, here’s where it gets interesting. Monday the 7th afternoon is your first real standout. The wind goes glassy – dead calm – off a 4 ft SW swell with a long 13-second period. That’s clean, that’s smooth, that’s the kind of session you remember. The combined energy’s solid at 560. Kua Bay (Big Island) is an exposed spot, and with the swell coming from the WSW, it’s close to that optimum WNW direction. It’ll be surfable, but with crowds “sometimes,” so keep an eye out for company.

Then Tuesday the 8th... whoa. This one’s a beast. Monday night into Tuesday morning, the swell jacks up to 8 ft from the WSW with a 15-second period. That’s groundswell territory – long, lined-up, powerful. The combined energy is a massive 2998 – that’s strong. The wind is cross-offshore from the SSW at 12 mph, which will groom the faces. But here’s the reality check: 8 ft is expert-only. If you’re not solid, sit this one out. By Tuesday afternoon it’s pushing 10 ft with a 13-second period – still massive energy at 2778 and still cross-off. This is a legit big-wave day for the skilled crew. It’s going to be a wild one, but it’s also the best on offer in this whole window.

After that, it fades fast. Wednesday the 9th drops back to 3 ft with onshore wind... junk. Thursday the 10th into the second week is mostly small and weak, with a lot of flat patches. A few 1 ft pops here and there, but nothing with any push. The 15th has a 1 ft SW swell with a super long 21-second period and 154 in energy, but the wind is cross-onshore – that’s just a tease.

So, to wrap it up: if you’re surfing Kua Bay, the standout is absolutely Tuesday the 8th for the big-wave chargers. Monday afternoon the 7th is the cleanest, most approachable swell. The rest of the 16 days is mostly a flat or ugly wait.

Stay keen,
Rusty.
