Alright, Rusty here. Let's break it down.
Honestly, it's a rough stretch ahead. The first week and a half is mostly a washout at James Kealoha Beach Park, with a few promising days way out in the forecast. Water temp is about what you'd expect for this time of year.
From the 9th of July through the 17th, it's all cross-onshore wind, chopped-up surf, and marginal conditions. The swell is running 4 to 5 feet, but with a short period of 7 to 8 seconds, it's gutless. The combined wave energy is weak to moderate (under 500), so it's just messy. A few sessions are tagged "marginal," but it's not worth the hassle. This is a pretty typical blank run for this spot.
The one real bright spot is the morning of Saturday, 18th July. The wind swings light cross-offshore from the ESE, cleaning it right up to glassy. The swell hits 8 feet, from the ENE, with a 9-second period. That's a solid, powerful groundswell, and the combined energy is a massive 1864 – that's strong. This is for experienced surfers only; it's way too big for beginners. It's a reef break, so it should handle the size, but it's going to be a heavy, powerful wave.
After that, it fades. The swell drops back to 7 feet on the 19th, but the winds turn back cross-onshore, making it choppy again. There's a weird pulse on the 20th and 21st of July with a very long period of 16 seconds and smaller 4-foot swell. That's real groundswell, but it's coming from the east, and with light cross-onshore winds, it'll be lumpy. That long period energy would be better at a deeper reef, not here with the wind on it.
The last chance is the morning of Thursday, 23rd July. It's glassy, dead calm, with a 3-foot swell from the ENE at 10 seconds. Combined energy is a weak 222, but for a clean, glassy session on a longboard, it might be your only quiet one. It fades to nothing after that.
So, the call: The morning of Saturday, 18th July is the one to wait for. It's the only time we get big, clean, powerful surf for the experts. The rest is a waiting game.
Rusty.
