Alright, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Honestly, it’s a tough run. The whole 16-day window is pretty much a write-off. There’s not a single session that I’d call worth paddling out for. The first day with any surf on offer is Saturday, July 11th, but right from the get-go, the conditions are a mess. The water temp is sitting at 79.2°, which is about average for this time of year, but that’s where the good news ends.
The only break on the radar is Wailua/Horners, a reef setup that’s built for advanced crew. It’s inconsistent, and when it does break, crowds are often an issue. The swell is coming from the ENE, but this spot needs a north swell to really line up, so direction is all wrong. The swell height floats around the 4.9 ft to 7.2 ft mark, but the period is short—around 7 to 8 seconds. That’s weak, wind-swell energy. The wave energy is moderate, with values like 475 (Saturday morning) and 584 (Sunday morning), but it’s just not translating into any quality. The wind is onshore, blowing a moderate 15 to 16 mph from the ENE, and the wave comment is consistently “poor surf conditions.” Everything is scored a 0 out of 10.
It’s a solid 16-day gap with no standout options. The only thing that shifts is around Monday, July 14th, when a long-period 16-second west swell tries to push through, but it’s tiny (2 ft to 2.6 ft) and the wind stays onshore, so it’s a non-event. Kite surfers might find some interest in the consistent onshore breeze and head-high bump, but for the paddle crew, it’s a flat spell.
Hang in there, but don’t hold your breath. The forecasts can change, but right now, it’s a tough stretch.
