The Lowdown
Alright, this is Rusty checkin' in from the shores.
Well, I gotta be straight with you – the next sixteen days are lookin' like a total write-off for a decent paddle. We've got a solid onshore wind hammerin' us from the east-nor'east, and it doesn't let up once. The water temp is sittin' right around average for the time of year at 80.6°, nothin' weird there, but that’s about the only thing that's normal.
We're talkin' Wailua/Horners (Kauai) for the whole run, a reef setup that can handle some juice, but it's just not on. For the first week, from Monday the 24th of August right through to Saturday the 30th, it’s a constant stream of onshore wind and poor surf conditions. The swell is mostly from the east with a short, weak period of just 7 seconds. Heights hover around 4 ft to 5.6 ft, but it's so chopped out and messy, you wouldn't wanna be out there. The combined energy is weak to moderate, topping out around 474 on the 29th, but it's just not clean. Not a single day in that first stretch gets a pass.
We roll into the second week, and it’s the same sad story. From Sunday the 31st of August all the way through to Monday the 7th of September, it’s just more of the same. The wind stays onshore, the period stays short, and the forecast keeps callin' it "poor surf conditions." Honestly, the only thing that changes is that from the 1st of September, the swell period climbs to 9 seconds and the height bumps up to 6.9 ft, even pushin' the combined energy into the 600s. But it's all for nothin' with that wind. It's blown out, messy, and way too big for beginners at over 5 ft anyway.
Then, right at the very tail end on Tuesday the 8th of September, the swell direction swings around to the northwest with a super long 16-second period. The height is only around 2 ft, but the energy jumps back up. But again, the wind is howlin' onshore at 15-18 mph.
Mate, this is just one of those blank runs. The whole sixteen days is a bust. The onshore wind just never gives us a window. For a spot that's exposed like this, it's not unusual to get a stretch like this when the trades lock in. Maybe it's more of a kitesurfer's playground with that wind and some of those 5 ft+ days, but for a paddle surfer? Stay at home. The forecasts can change, but right now, there is nothin' on offer.

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.

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.
