Alright, Rusty here again, same story, different numbers. For Wailua/Horners, it’s a long stretch of ugly. This is an advanced reef spot, but the ocean is just not cooperating. Water temp is about 79°, dead average for the season, so at least you won’t get cold while you’re waiting for a wave that isn’t coming.
The wind is the villain. From Sunday the 5th right through the first week, it’s 15 to 19 mph onshore from the ENE, blowing straight into the waves. The swell sits around 7 ft to 8 ft from the ENE, with a short, weak period of 8 seconds. The combined swell energy runs from 434 to 651 – moderate on paper, but worthless with that wind. Every single session is flagged as “poor surf conditions,” scoring a zero. The spot is “inconsistent” anyway, so a dry spell is part of the deal.
This same pattern sticks around for days. Onshore wind, lumpy, short-period slop. No relief.
Then on the 14th and 15th of July, a glimmer. A tiny groundswell shows up – only 3 ft to 3 ft, but with a very long period of 16 seconds. The combined energy peaks at 789 on the 15th, which is respectable. But the wind is still onshore at 12 mph from the ENE. On a reef, that long period could have given you some beautiful lines if the wind was right, but it’s not. Still called “poor surf conditions.”
There’s one flicker on Thursday the 16th afternoon – a 6 ft swell from the E, period of 7 seconds, and the wind drops to a gentle 9 mph onshore. It’s called “marginal” at best, a score of 1 out of 10. That single afternoon is the only session in the entire 16 days that isn’t a complete write-off. A 6 ft, short-period wave with onshore wind… it’s a gamble, not a guarantee.
The rest of the second week slides back into the doldrums: 4 ft to 5 ft short-period E swell with 9 to 12 mph onshore winds. The combined energy drops to the low 200s and 300s – weak, messy, and not worth your time.
I can’t give you a standout. There’s no day where the stars align. If you absolutely must paddle out, keep an eye on that Thursday the 16th afternoon for the best of a bad bunch. Otherwise, this setup looks more like a kiter’s game than a surfer’s.
Hang tight. Things can turn around.

Information about the Wailua/Horners Surf forecast
The above surf forecast table for Wailua/Horners provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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. If you surf the same spot (Wailua/Horners) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
