The Lowdown
Alright folks, Rusty here. Let’s be straight with you—this 16-day window for Wailua/Horners is a tough one. The forecast is pretty much a long stretch of "poor surf conditions" with only a brief, flickering moment of hope right at the end of the month.
We’ve got a persistent onshore wind from the ENE blowing at 12 to 16 mph for most of the period, which is just trashing the surface. The swell is coming from the east, but the energy is all over the place. In the early days, the combined swell energy is sitting around 400 to 600 (moderate), but it’s short-period windswell of 7 to 8 seconds, so it’s weak and wonky. The water temp is a normal 80°F for this time of year, but that’s about the only thing that’s normal.
The most promising window is the afternoon of Thursday, the 30th of July. The wind drops right out—going glassy with a light SW breeze. The swell drops to 4ft from the ENE, period 8 seconds, and the combined energy drops to 315 (weak). The wave comment says "expect good surf conditions." That’s a real standout. For a spot that’s marked as "inconsistent" and often crowded, a glassy afternoon with waist-high waves is a rare treat. It’s the only real surfable moment in the whole 16 days.
After that, the wind picks right back up on Friday morning, and we’re back to the same old story. A few pulses of longer period swell (14 to 17 seconds) show up in the second week, giving combined energy spikes over 1000 (strong) on the 3rd of August, but the wind is still onshore and the conditions are still "poor." It’s a tease—bigger, groundswell energy but no clean face to ride.
The rest of the run is a washout. Gaps of several days with zero recommendations. The consistent ENE breeze and onshore chop just won’t let up. This isn’t a spot for beginners anyway, it’s an advanced reef break, and with the swell over 5ft most days, it’s edging into expert territory, but nobody’s going to enjoy it in these winds.
Keep an eye on that Thursday afternoon, 30th of July. If you can get a pass, that’s the one. Otherwise, sit this one out.
Rusty.
