The Lowdown

Alright, let’s get into it. These next 16 days? Honestly, they’re looking pretty barren for Wailua/Horners. We’ve got a solid stretch of nothing but poor surf conditions lined up, and that’s a tough one to take.

Right off the bat, for the next several days, we’re looking at weak, short-period slop. The swell is small, the energy is low – we’re talking combined energy readings in the low hundreds, like 5 to 6 feet of mix, which just isn’t enough to get this spot working. The wind is onshore and blowing sideshore, which just makes it a total mess. Water temp is sitting at around 80°, which is about average for this time of year, so you won’t need a thick suit, but you might not even bother paddling out for this dribble.

There’s a bit more energy kicking in around Thursday the 17th and Friday the 18th, with the swell bumping up to the 5 to 7-foot range. The combined energy jumps up to 391 and then 569, which is a sign of more push, but the period is still short, and the wind is cross-onshore with a risk of thunderstorms. It’s still going to be messy. This isn’t a tap-in, it’s a battle.

The mid-period, from around the 20th to the 22nd, sees the energy settle into the moderate range, but the waves stay below 7 feet and the period remains short at 8 seconds. It’s more of the same – onshore winds, poor conditions, and a lot of chop. Nothing to get excited about.

Then, around the 23rd and 24th, we finally see a pulse of real groundswell. The period jumps up to 11 and 12 seconds, and the combined energy goes through the roof, hitting 1239. That’s strong energy, and the swell is pushing 7 feet. But here’s the catch – it’s still coming from the east, which is straight onshore for this break, and the wind is still on it. The potential is there, but the conditions are going to make it a mess. For the experts out there, this could be something, but for everyone else, it’s going to be a washing machine.

The wave heights stay solid into the following week, around 6 to 6 feet, but the period drops back down to 7-8 seconds. It’s still blown out with onshore winds. The energy readings stay in that strong range, but again, the quality just isn’t there.

Overall, this is a tough stretch. The best window on paper, around the 23rd and 24th, is going to be for experts only due to the size and the onshore wind. But even then, the quality is questionable. This spot is an inconsistent reef break, so you need the stars to align, and they are far from aligned here.

There are no good surf options in this 16-day window. It’s a blank run, and that’s just how it goes sometimes. The forecasts can change, but right now, it doesn’t look like it’s going to get good. The potential for a bigger, longer-period swell to light it up is there, but the wind direction is killing it. It’s a waiting game.

Rusty out.

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.
