The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the next 16 days. I'm going to be straight with you – it's a rough run for Wailua/Horners. The forecast is showing a whole lot of nothing good for a while.
The first recommendation doesn't come until Tuesday, August 4th, but don't get your hopes up. The week kicks off Friday, July 31st, with some east swell around 6ft, but it's coming with a short 8-second period and a moderate onshore breeze, so it's messy and poor. That pattern sticks around through the weekend and into Monday. It's a flat spell of poor surf conditions.
We finally see a slight shift on Tuesday morning, August 4th. The swell drops to 5ft, but the period stretches out to 12 seconds, which is a groundswell. The wind is a gentle onshore breeze, but the overall energy is still moderate (658). The call is marginal at best. It's the only spot in the whole window that gets a nod, but it's still a tough sell. The water is sitting at 80°, which is perfectly average for the time of year, so no shocks there.
Honestly, looking at this, there's no standout session. The whole 16-day window is plagued by onshore east-northeast winds and short-period, choppy waves. The combined energy stays moderate (between 143 and 1155), but it's all wind-affected.
After that Tuesday morning blip, it's back to poor surf conditions right through to the end of the window on Saturday, August 15th. There's a few pulses of energy, even a long-period west swell showing up on the 14th and 15th, but those are accompanied by thunderstorms and strong onshore winds, so it's a write-off. For a reef break that needs clean conditions, this is a long, dry spell. It's a tough one to call, but I'd say park the board and wait for the next forecast update.
