The Lowdown
Alright folks, Rusty here with a look at the surf ahead for Wailua/Horners.
We’ve got a pretty rough start to this 16-day stretch. For the first few days, it’s gonna be a write-off. We’re looking at a lot of wind-blown slop and rain early on, so don’t even bother paddling out on the 7th – it’s just not happening.
Things start to look a little more interesting around Tuesday the 8th. The wind swings around, cleaning things up a bit, and we get a pulse of energy from the ENE. The swell is a solid 7ft to 7ft with a decent 11 to 12-second period, and the combined energy is pumping (1259). It’s a groundswell, which means those waves will have some punch, but with that direction, it’s coming straight onshore here, so it won't be perfect. Still, it’s the best we’ve got for a few days.
But the real standout, the one you want to circle on your calendar, is Wednesday the 9th morning. The ENE swell drops to a more manageable 4ft, the period is still a nice 9 seconds, and the wind goes super light and variable, sliding cross-offshore. The energy is moderate (555), but with those clean conditions, this is your window. The water temp is about average for this time of year, so no surprises there. Just keep in mind this spot is an advanced reef break that’s inconsistent, and it does get crowded often, so get there early if you want a peak.
After that Wednesday morning window, it’s a long, painful dry spell. From the 9th afternoon right through to the end of the 16-day forecast, the wind is just crap. It’s onshore or cross-onshore, the swell period drops to a short, choppy 7 to 8 seconds, and most of the energy readings are in the low hundreds (between 116 and 556) – that’s weak and average at best. It’s just not going to be worth the paddle for anyone. Honestly, with the wind and the size in the later part of the forecast, this setup looks a whole lot more interesting for kite surfing than for a proper surf.
So, short story: Your only real shot at something decent is early Wednesday the 9th. Get there if you can.
Rusty.
