The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Wailua/Horners.
Right off the bat, I gotta be straight with you – the next couple of weeks are looking pretty average. The surf starts off small and bumpy, and it doesn't really get its act together. The first record we see is for Saturday, August 1st. That afternoon, we’ve got a 8 ft east swell rolling in, but with a 16 mph onshore breeze from the ENE, it's gonna be messy. The water temp is sitting at 80°, which is about normal for this time of year, so the wetsuit can stay at home.
Moving into Sunday August 2nd and Monday August 3rd, it’s more of the same – 8 ft to 5 ft east-northeast swell, but that onshore wind just won't quit. The combined wave energy is moderate, hitting around 1067 on Saturday but dropping off through the weekend. It’s not looking good for a paddle.
Now, Tuesday August 4th shows a bit of a glimmer. We get a cleaner 5 ft swell from the ENE, and the period stretches out to 12 seconds, which is a nice proper groundswell. The wind drops to a gentler 9 mph, but it’s still blowing onshore. The energy is moderate at 647. The report calls it marginal, and I’d agree – it might be worth a look if you’re desperate for a session, but don't get your hopes up. This break is an advanced reef, so you want it clean.
The rest of the first week into the second week is a write-off. From Wednesday August 5th right through to Wednesday August 12th, we’ve got small, weak swell, crappy onshore wind, and the wave energy drops right off to as low as 64. There’s even a risk of thunderstorms in there. You’d be better off doing something else.
Then, things get a little weird. From Thursday August 13th through to Sunday August 16th, the swell direction swings around to the west. The swell heights are tiny, just 2 ft to 3 ft, but the period gets very long – 15 to 17 seconds. That’s a lot of energy in the water for a small wave, with the combined energy climbing back up over 500. The problem? The wind is still hammering onshore at 16 to 19 mph, and there’s a risk of thunderstorms or rain showers. For a beach and reef setup with that much onshore wind, this looks like it’d be more fun for the kite crew than for us surfers.
To be honest, there isn’t a single standout session in this whole 16-day window. It’s a long, flat, windy run. The break itself is inconsistent and when it does get going, the wind usually ruins it. It’s a tough forecast.
Stay patient, check back later. Forecasts can change.

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.
