The Lowdown
Alright, Rusty here. Let's talk surf.
I gotta be honest, for the first week of this 16-day forecast, you're better off staying home. We've got a solid run of onshore wind from the ENE, cross-on all day, making a mess of things. The swell is short-period, around 7-8 seconds, and the energy is weak, barely cracking 400 (combined energy). The water is 80°F, which is about normal for this time of year. It's just not worth paddling out.
Then, on Wednesday the 29th of July, the light turns on. Rivermouth_Wailuku (a reef break) finally gets a break. The wind goes light WSW, cross-off in the morning, and the swell hits 7ft from the ENE. The period is 10 seconds, and the energy is 913 (moderate). The report says "expect very good surf conditions." This is the one. It’s a solid, clean wave with the wind at your back. The afternoon gets a bit messy with a cross-shore, so the morning is the call.
After that, it's back to the grind of onshore wind and average waves. The next real chance comes on Friday the 7th of August. The morning shows a light breeze from the south, cross-off, with a 4ft swell from the NE. The period is short, 9 seconds, and the energy is low at 294, but it’s clean. The afternoon is similar with a 5ft swell. It's not a big day, but it’s the last clean window in the forecast.
Bottom line: you've got one standout morning on the 29th of July. Friday the 7th of August is a backup for a clean, smaller session. The rest is a write-off.
Rusty.
