The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s on the menu for the next 16 days at Wailua/Horners. I’ll be straight with you – it’s pretty grim. The whole stretch from today, July 19, right through to August 3, is filled with one “poor surf conditions” after another. There’s not a single standout session in the bunch. The only flicker of something slightly less terrible is on Monday 27 July afternoon, where it’s labelled “marginal” – but even that’s a 1 out of 10, so don’t get your hopes up.
This spot is a reef break, always tricky, and it’s inconsistent – it doesn’t fire often. When it does, it needs a clean north swell, but the predominant swell direction we’re seeing is from the east and east-northeast, which is way off. On top of that, the wind is blowing onshore from the ENE and NE almost every day at 9 to 16 mph – that’s a moderate breeze, not helping. The swell periods are short, mostly 7 to 8 seconds, so the waves are weak and choppy. Even when the period gets long on 26 and 27 July – 16 to 17 seconds – the wind is still onshore, so those long-period lines get chopped up before they even reach the reef. The combined energy is moderate (in the hundreds), but it’s all wasted with poor conditions.
What does this mean for a surfer? Honestly, don’t bother. The water temperature isn’t mentioned, but with that onshore wind and short swell, you’ll be fighting for nothing. The break is often crowded when it’s good, but right now it won’t be crowded because nobody’s out. A blank run like this is normal for an inconsistent spot like Wailua/Horners – it’s just the way it goes. Forecasts can change, but for now, save your energy.
Rusty.
