The Lowdown
Right then, Rusty here. Let’s have a look at what’s cookin’ for Wailua/Horners.
Truth is, mate, for the next 16 days, this spot is a write-off. The whole window is a blank run of poor surf conditions. There’s a solid 16-day gap with no recommendations at all. The wind is hammering onshore from the east-northeast the entire time, and that’s just gonna chop everything to pieces.
The water temp is sittin' at 80°, which is basically bang on average for the time of year, so no surprises there.
The first few days are a total mess. On Tuesday the 4th, we’ve got a 5ft swell from the east-northeast, but it’s onshore wind and a risk of thunderstorms. Combined wave energy is moderate at 494. It’s poor.
Wednesday the 5th and Thursday the 6th are more of the same – onshore ENE wind, 5ft to 4ft of weak, short-period slop. Friday the 7th drops to 3ft with a period of just 6 seconds and energy down to 95. It’s barely surfable.
The second week doesn’t get any better. By Sunday the 16th, the swell pushes up to 8ft from the ENE with a period of 9 seconds, but the wind is still howling onshore at 16 mph. The energy jumps to 866, which is strong, but it’s a total wind-blown mess. By Tuesday the 18th, we’re looking at 10ft from the ENE with a period of 9 seconds and energy over 1600 – that’s very strong wave energy. But again, it’s all onshore garbage. That’s expert-only territory, and only if you’re keen on a beating.
There is no standout. There is no best on offer. The setup here is so wind-affected it’s looking more interesting for kite surfing than paddle surfing. The swell direction is ENE, which is the wrong side of the compass for this reef. It’s an inconsistent break that rarely lines up, and when it’s like this, you’d be better off stayin’ home.
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.
