The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks at Wailua/Horners over on the east side.
It’s a pretty grim start, I’m not gonna lie. We’ve got a solid run of poor surf conditions kicking off this Thursday afternoon, September 3rd, and it’s gonna be a long wait. The first few days are just a write-off. The wind is hammering onshore from the NE and ENE at 15 mph, and the swell is a messy, short-period chop. Combined wave energy is moderate at best early on, but it’s all blown out and ugly. That run of junk lasts right through until Sunday, September 6th, with the wind actually picking up into a fresh breeze and even a near gale by Monday the 7th. The swell gets big—up to 14.8 ft on Monday afternoon—but it’s a total mess with that cross-onshore wind. Unless you’re looking to get your kite flying, this is a stay-at-home kind of stretch.
The first real sign of life doesn’t show up until Tuesday, September 8th. The wind finally swings around to the SSW, giving us a cross-offshore breeze and clean conditions. The swell drops back to 6.6 ft in the morning and 5.2 ft in the afternoon, coming from the ENE with a decent 11-second period. The combined energy is still strong (1361 and 729), so there’s meat on the bone. But the surf forecast is only marginal, and this spot is an advanced, inconsistent reef break that often gets crowded. It’s tricky, but if you’re a seasoned local and you can pick your peak, Tuesday morning and afternoon are your best bet in the whole outlook. The water temperature is 80.8°, which is pretty much normal for this time of year.
After that, it’s back to the same old story. From Wednesday, September 9th, through to the end of the forecast on September 18th, it’s a long stretch of onshore ENE wind and poor quality. The swell hangs around between 2.6 ft and 7.2 ft, but the wind is relentless and the conditions are blown out or just marginal at best. There’s a brief spike in energy around the 15th (1446) with a 7.5 ft ENE swell and a 10-second period, but the wind is still onshore from the ENE, so it’s probably not worth the drive.
Honestly, the standout here is Tuesday, September 8th. That’s your window. It ain’t perfect, but it’s the only clean surf we’re gonna see for a while. Get it while you can.

Information about the Wailua/Horners Surf forecast

A general guide to surfing at Wailua/Horners can be found by selecting the local surf guide option on the grey menu. Our Wailua/Horners surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
