Alright folks, Rusty here. Let’s have a look at what’s on the cards for the Wailua/Horners zone over the next couple of weeks.
Right off the bat, I gotta be straight with you – this one’s a tough run. We’re looking at a solid 16-day stretch where the conditions just aren’t playing ball. The whole outlook is flagged as poor surf, and honestly, I can’t find a single standout session to get excited about. There’s no real kick-off to the period; it’s just a long, flat-to-messy grind from the start.
For the first week and a half, from Thursday the 9th right through to around Monday the 20th, we’ve got a constant onshore breeze from the ENE, blowing at 12 to 16 mph. That wind is just ruining any chance of clean waves. The swell is hanging around the 5 ft to 8 ft range, mostly from the E and ENE, but with a short, weak period of 7 to 8 seconds – that’s windswell, not groundswell. The energy is there, reading between 240 and 638 (moderate), but it’s all chopped up and messy. Not a single clean window in that whole stretch.
Then, around Tuesday the 21st and Wednesday the 22nd, things get weird. The swell drops to 3 ft to 5 ft, but the period jumps way up to 15 to 20 seconds. That’s a very long period groundswell rolling in from the east. The combined energy spikes into the four-digit range (1116 to 1462), showing strong energy. But here’s the kicker – the wind is still onshore, 12 to 16 mph from the ENE and NE. That’s a brutal combo. A long period swell like that needs clean, glassy conditions to really shine, especially at a reef break like this. With that wind, it’s just going to be a bumpy, difficult paddle. The swell direction is E, which is not the optimum N direction for this spot, so it’s not wrapping in perfectly either. It’s a heartbreaker, but that’s the call.
The last few days, the 23rd and 24th, the swell fades back to 3 ft to 5 ft, period drops, and the wind stays onshore. The water temp is sitting at 79°F, which is about normal for this time of year, with a tiny anomaly of +0.4°F. Water temperature anomaly is about average for the time of year.
So, bottom line: there is no good surf on offer in this 16-day window. The whole period is a washout. For a spot that’s normally inconsistent, this kind of blank run can happen. It’s a real bummer, but that’s the reality of the forecast. Keep your eyes peeled for a change in the wind pattern, but for now, I’d say leave the boards in the car and find something else to do.
Rusty.

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.
