The Lowdown
G’day, Rusty here.
Well, I’ve gotta be straight with you – looking up and down the entire 16-day window for this spot, it’s pretty grim. There’s really nothing to get excited about at Wailua/Horners. The whole run is a write-off, with zero standout days. We’re talking about a solid 16-day stretch of poor surf conditions through to the afternoon of August 17th, with every single session scored as a zero. No good options at all.
The pattern is stubborn, and it’s basically the same story day after day. The fetch keeps pumping in from the east-northeast and east, with onshore winds the whole time. The swell height bounces around a bit: starting off at 8 ft on Sunday afternoon, August 2nd, but that’s from the ENE at a short period of 8 seconds, so it’s pretty junky. The combined energy is moderate at 938, but that doesn’t help with the wind ruining the face. The water temp is a normal 80°F, so no drama there.
Through Monday the 3rd and Tuesday the 4th, the swell drops to 6 ft and 5 ft, but still with those onshore breezes – gentle to moderate, but onshore all the way. That easterly wind doesn’t let up, and when the period does stretch out to 12 seconds on Tuesday morning (4th August), it’s a groundswell that’ll likely wrap in a bit, but the wind’s still on it, so it’s not going to be clean. The energy stays moderate, ticking between 549 and 636. It just never cleans up.
From the 5th through to the 7th, things get smaller, the swell drops to 3 ft, and the period falls to 7-8 seconds – weak, short-period chop with only 107 to 356 in combined energy. Not worth paddling out for. Then around the 8th and 9th of August, the swell picks up again to 5 ft to 6 ft, but the period stays short at 7 seconds, and the wind is still onshore. The energy climbs to 406 on Sunday the 9th, but with risk of thunderstorms and a constant moderate breeze, it’s a messy, blustery scene.
The second week looks the same: no improvement. From the 10th to the 13th, we’ve got 5 ft to 6 ft swell with 7-second periods from the E and ENE, and onshore winds at 12-16 mph. On the 14th and 15th of August, the swell gets a bit bigger – up to 8 ft – but the period is still a paltry 8 seconds, and the wind is onshore and picking up, hitting 19 mph on Saturday the 15th and Monday the 17th. The energy climbs to a moderate 903 at its highest, but honestly, with that wind and short period, it’s just lumpy, bumpy, and blown out.
This break is an advanced reef, inconsistent, and often crowded. There’s no good wind direction here – the optimum swell direction from N, but we’re getting E and ENE swells, and the wind is onshore from the NE and ENE every single day. No standouts at all. It’s a total shutout for 16 days. Sometimes you just get a run like this in this area – nothing to do but wait for a change in the pattern.
Stay patient,
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.

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.
