The Lowdown
Alright, this is Rusty. Let’s take a look at what’s on offer.
To be straight with you, the next couple of weeks are a tough stretch. The only spot in the picture is Wailua/Horners, and it just can’t get it together for most of the run. We’re looking at a long block of poor right from the start.
The outlook starts off on the morning of Thursday, August 27th, but don’t get your hopes up. The swell is a weak 4ft from the East with a short, wind-chopped period of 7 seconds and moderate wave energy (170). And the wind? It’s blowing straight onshore from the ENE at 16 mph, making for messy, blown-out conditions. That’s the story through the end of the month: onshore winds, weak short-period swell, and "poor surf conditions" every single session. The water temp is 81°, which is about average for this time of year.
We roll into September with the same troubles. The swell does build a touch, hitting 7ft by Tuesday the 1st, with energy climbing into the moderate range (537 in the afternoon), but the wind stays on it. It ain’t until Saturday the 5th that things get a little interesting. The swell jumps to 7ft from the East with a longer period of 12 seconds, and the energy surges to 1174 – that’s a strong, powerful push. But even then, the wind is still onshore, and the call is only "marginal" at best. A 7ft wave with onshore wind at Wailua/Horners is a choppy mess, not a gem.
The chase for a clean session goes on, but it never arrives. The wind stays onshore or cross-onshore with moderate to fresh breezes right through to September 11th, when things get wild. On the morning of Friday the 11th, we’ve got a near gale blowing 34 mph from the NE, cross-onshore, making it a complete write-off for paddle surfing – that’s kite territory if anything. By the afternoon, the wind shifts to a cross-offshore from the NW at 31 mph, which cleans it up a bit, but the swell is a jumbled 6ft from a different direction, and the whole setup is just not happening.
So here’s the bottom line: there isn’t a single standout session in this whole 16-day window. It’s a long, frustrating gap. The conditions just don’t line up for a quality surf. The break itself is inconsistent, and when the swell does show some muscle, the wind ruins it. We’ll have to wait for the next forecast.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Wailua/Horners may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
