The Lowdown
Alright, Rusty here, checking the surf at Wailua/Horners. Gotta be straight with you – this is a dry spell. The whole 16-day window is nothing but "poor surf conditions," with no real standout in sight. Water temp is about 79°, which is normal for this time of year.
From Tuesday the 14th through the weekend, it’s a bust. We’ve got a tiny 2ft west swell, but onshore winds from the east and northeast at 12 to 13 mph are just tearing it up. Choppy, messy, and not worth a paddle. The wave energy is moderate, around 478, but it doesn’t help.
Come Saturday the 18th, the swell switches to a short-period east swell (7 seconds), and the wind is still onshore. The size bumps up to 4ft, but it’s not clean. This pattern sticks around through the middle of the week. By Sunday the 19th, we see 6ft from the east, but it’s still onshore with a short period, so it’s just a bumpy, jumbled mess.
The second week is the same sad story. From Monday the 21st onward, it’s onshore wind, short-period east swell, and poor conditions. The swell gets a little bigger around the 25th and 26th, hitting 6ft to 7ft, with strong wave energy up to 729. But it’s all onshore. At that size, with strong wind and a beach-and-reef setup, it’s looking more like a kite-surfing zone than a paddle spot.
For a break that’s inconsistent and only for advanced surfers when everything aligns, this is a total blank run. A full 16 days with no good options. That’s a rough one. It won’t stay this way forever, but right now, there’s nothing to recommend.
Rusty.

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.
