The Lowdown
Alright folks, Rusty here. Let’s take a look at the surf ahead for the next couple of weeks. I’ve got my eye on one spot, and I’m not gonna lie, it’s a bit of a tough read.
We’re looking at a long stretch of pretty ordinary conditions. The water temp is sitting at 80°, which is pretty much bang on average for this time of year, so no surprises there.
The only break on the radar is Wailua/Horners. It’s a reef set-up, exposed to the swell, and it’s inconsistent, so you’ve got to be patient. The swell direction it really wants is from the north, but we’re not seeing that for a while.
Starting from Saturday, 22 August, right through to the end of the month, it’s all poor surf conditions. Winds are blowing onshore from the ENE, with speeds around 9 to 16 mph. The swell is small, mostly around 3 ft to 6 ft, coming from the east, with a short period of just 7 seconds. The combined energy is moderate, ranging from 140 to 471, but with that wind and short period, it’s just not going to shape up. It’s a write-off.
We roll into the first week of September, and there’s a flicker of hope. On Tuesday, 1 September, the swell picks up to 8 ft from the ENE with a period of 9 seconds – that’s a bit more energy in the water (788). But the wind is still onshore at 12 mph, and the forecast still says poor surf. On Thursday, 3 September, we get a slight improvement. The wind drops to a light breeze, 6 mph, and the surf is 7 ft to 7 ft from the ENE. The combined energy is strong (585), and the conditions are only flagged as *marginal* rather than outright poor. This is the closest we get to a go. It’s still not perfect, but it’s the only time the window cracks open. The swell is still a bit short-period at 8 seconds, but that light wind could make it rideable. The swell direction is ENE, not the optimum north, but it’s our best bet.
After that, Friday the 4th through Sunday the 6th of September, we’re back to poor surf. The wind picks up again, with a strong breeze of 28 mph on the last day, making it messy and lumpy.
So, to be straight with you: there’s no standout session in this 16-day window. The only real chance to get wet is on Thursday, 3 September, when the wind goes light and the swell is a solid 7 ft. But even then, it’s a marginal call. For the rest of the time, with the onshore winds and short period swell, it’s more of a kite-surfing setup than a pure paddle session. The crowds might be around, but honestly, I don’t think many will be keen.
Hang in there, though. Forecasts can change.
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. 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.
