Kua Bay Surf Forecast and Surf Report

Alright, this is Rusty.

Let’s be straight with you. Looking at Kua Bay (Big Island) over the next sixteen days, it’s a tough stretch. The swell is just tiny, and the conditions are mostly messy. We’re talking about a long haul of poor surf, so don’t get your hopes up for any real barrels. The first real glimmer of something surfable, and I mean barely surfable, doesn’t show up until Monday, the 17th of August.

The water is sitting at 82°F, which is a touch warmer than normal for this time of year, so that’s a nice perk if you just want a float.

Let’s go through this. The first week is a write-off. From Thursday the 6th right through to Sunday the 16th, it’s just a parade of flat days and knee-high dribble. The wind is mostly cross-on or light, and the combined energy is pathetic, staying under 100 (typically between 11 and 61). There’s a glassy moment on Saturday the 8th afternoon, with 3 ft from the NE, but the period is a short 6 seconds, so it’s just weak, wonky windswell. Not worth paddling out for.

The real standout, and I mean the only spot that even gets a pulse, is Monday the 17th of August in the afternoon. We see a long-period groundswell of 1 ft from the WNW at 14 seconds, with the combined energy finally pushing up to 84. The wind goes clean, a cross-off from the SSW at only 3 mph. This is the best of the bunch, but let’s be real, it’s still tiny. The long period (over 15 seconds would be very long, so 14 seconds is good) means the waves will have some shape and energy, but Kua Bay is an exposed beach, so that long period could make it break a bit straight. Still, it’s the only time the report says "surfable waves" instead of "poor." This is your best bet, but it’s a micro-session.

After that, the rest of the week into the 21st goes back to the same flat and blown-out story. The wind stays light, but the swell barely registers. Saturday the 15th has a glassy afternoon with 1 ft from the WNW, but the energy is a paltry 26.

So, to sum it up: if you’re a kitesurfer, the consistent cross-on winds might be interesting, but for a surfer? It’s a long, flat stretch. The one afternoon to keep an eye on is Monday the 17th. It’s not going to be memorable, but it’s the only game in town.
