The Lowdown

Hey folks, Rusty here. Gotta be straight with you – the next couple of weeks look pretty grim for Wailua/Horners. We've got a solid 16-day window ahead, but honestly, there's nothing to get excited about for a long stretch. The first real chance of anything decent doesn't show up until way down the line.

See, the problem is that for the entire first week and a half, we're stuck with a constant onshore wind from the east-northeast, blowing at 12 to 16 mph, and the swell is all short-period, wind-driven stuff. The wave heights hover around 4 ft to 6 ft, but with periods of just 6 to 8 seconds, there's no power or shape. The wave energy is weak to moderate at best, with the combined energy readings sitting around 131 to 429. It's just poor surf conditions day after day. The water temp is sitting at 80°, which is bang on average for this time of year, so nothing unusual there.

We finally start to see a flicker of something on Saturday, September 5th. The morning shows a bit of a bump with 7 ft from the east-northeast, and the wind drops to a gentle 9 mph onshore. The energy climbs to 711, which is moderate, but it's still onshore and the waves are just messy. The swell really starts to build on Sunday, September 6th, with 8 ft in the morning and 10 ft in the afternoon from the east-northeast. The period jumps to 11 seconds, which is a proper groundswell, and the energy skyrockets to 1655 and then 1953. That's strong wave energy. The wind stays light, 9 mph onshore, but the size is getting big. Over 8 ft is expert-only territory, so this is not for the faint of heart.

The real standout – if you can call it that – is the Sunday afternoon session on September 6th. That 10 ft east-northeast swell with 11-second period and light 9 mph onshore wind is the most powerful we'll see, but it's still onshore, so it's going to be a battle. For the experts who can handle it, there might be some heavy, challenging waves. For the rest of us, it's more of a "watch from the beach" kind of day. The following Monday, September 7th, fades quickly, with the swell dropping back to 6 ft to 6 ft and the wind picking up again.

So, there you have it. A long, dry spell with one very late, very big, and very challenging option for the pros. Keep your eyes on the forecast, but don't hold your breath.

Rusty.

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.
