The Lowdown
Alright, Rusty here. Let's take a look at what's shaping up for Wailua/Horners over the next couple of weeks.
Honestly, it's a pretty bleak run for this spot. The whole 16-day window is basically a write-off for any kind of decent surf. There’s no standout period, no hidden gem days – just a whole lot of onshore wind and messy conditions. You're looking at a long stretch of nothing much to get excited about.
It all kicks off with a stormy setup. Through the 6th and 7th, we've got a decent sized swell pushing in, around 7ft to 10ft from the east, with a moderate wave energy (1634 to 1766). But that's where the good news ends. The wind is howling onshore from the east at 15 to 22 mph, and with the threat of thunderstorms, the surface is going to be a complete mess. This isn't a paddle-out situation; if anything, that strong wind and lumpy sea might be more interesting for the kite crew.
The 8th offers a tiny glimmer. The wind swings to a cross-offshore from the SSW, and the swell drops to about 7ft from the ENE, with moderate energy (1083 to 1169). The sea state cleans up, which is a major positive, but the overall surf quality is still rated as marginal. It’s not going to be the session of your life, but if you’re desperate, the Tuesday afternoon window with that lighter cross-off breeze is the best you’ll see in this entire outlook.
From the 9th onwards, it’s a downhill slide. The swell drops right off, dipping below 5ft for most days, and the energy levels fade into the weak-to-moderate range (under 600). The wind stubbornly sticks to onshore or cross-onshore from the east and northeast, keeping things choppy and poor. The only break that *might* offer a clean face is the Wednesday morning (9th) with a light cross-shore breeze, but the swell is tiny at 4ft from the northwest and the period is short at 10 seconds, so it’ll be weak and lumpy.
For the second week, from the 13th through the 21st, don't even bother. The swell stays small, the period drops off, and the onshore breeze is relentless. The combined energy values drop into the low hundreds, with some days barely cracking 100. This spot is just not going to have any quality waves in this timeframe.
Bottom line: For a break that’s already known to be inconsistent, this is a particularly blank run. It’s not abnormal for the area to go quiet, but this is a long quiet spell. Keep an eye on the forecasts, but don’t hold your breath.
Rusty.

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.

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.
