The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Wailua/Horners.
To be straight with you, this 16-day window is a tough one. We’re looking at a long stretch of poor surf quality with onshore winds hammering the break day after day. The water is sitting at 81°F with a water temperature anomaly of 0.7°F, so that’s about average for the time of year. The first real chance of anything worth paddling out for doesn’t show up until Wednesday, September 9th, and even then it’s only a marginal shout.
From Saturday, August 29th, right through to Tuesday, September 8th, it’s a dead zone. The wind is coming in from the ENE at 12 to 19 mph, mostly onshore, and the swell is a messy mix of short-period, wind-affected waves. The combined energy of all swells directed here is weak to moderate, ranging from 322 to 1191, but it’s all blown out. The wave comment for every single session reads “poor surf conditions.” That’s a solid 10-day gap where you’re better off doing something else.
We finally get a flicker of hope on Wednesday, September 9th. The afternoon shows a “marginal surf forecast” with a score that suggests it’s barely worth a look. The swell is 8ft from the ENE with a period of 9 seconds, and the combined energy is strong at 1071. The wind is still onshore from the ENE at 12 mph, but it’s a slight improvement. Still, this is not a standout. It’s a last resort for the desperate.
The next chance is Saturday, September 12th, in the afternoon. Again, a marginal call. Swell is 8ft from the E with a period of 9 seconds, and the combined energy is strong at 1191. The wind is onshore from the ENE at 12 mph. The problem is the same – the wind is working against the waves.
The real kicker is that this is an exposed reef break, and it’s inconsistent. It rarely seems to be in good shape. The optimum swell direction is from the N, but we’re getting nothing but ENE and E swells. The crowds are often there, but with this quality, they’ll probably be a lot thinner.
If you’re an expert and you’re absolutely itching, the afternoon of September 12th might be your best bet, but keep your expectations low. The swell is over 8ft, so it’s for experts only, and the wind is a problem. The setup here, with the strong onshore winds and the size of the swell, honestly looks more interesting for kite surfing than paddle surfing right now.
It’s a bleak run, but it tends not to stay poor for long in this area. Forecasts can change.
Rusty.

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.
