Rivermouth_Wailuku Surf Forecast and Surf Report

Alright, Rusty here. Let's talk about Rivermouth_Wailuku over the next couple of weeks, and I gotta say, it’s not looking good for a proper surf.

Pretty much the whole 16-day window shows poor surf conditions. The wind is stuck in from the ENE, blowing cross-onshore, which just churns up the surface and makes everything choppy and messy. There’s no standout day in this forecast. The swell is coming from the ENE with short periods around 7 to 8 seconds, so it's weak, crumbly, and just not packing any punch. The combined swell energy is moderate for the first week, with readings between 268 and 371, but it drops to weak levels below 99 after the 14th of July, meaning things really go flat.

There’s an odd moment on the morning of the 14th of July where the swell direction swings to the WNW with a very long 15-second period, but that's attached to a tiny 1ft wave with a combined energy of just 201. That kind of period is great for power, but there's no size behind it. The water temp is about average for the time of year.

For the first few days, the swell is around 5ft to 6ft. It's not too big, but with that constant east-northeast wind, it’s going to be blown out. The peak energy comes around the 4th and 6th of July, but with the poor conditions, it's a no-go. Honestly, with this reef setup and the persistent onshore wind, this looks more interesting for kite surfing than paddle surfing for that first week. There are no clean windows to escape the chop.

After around the 11th of July, the swell drops way off, and by the 14th through the 16th, we're looking at just 1ft to 3ft, if that. The energy is weak, and it’s just flat and unappealing. I can't find a single green light for a paddle here.

Sometimes the trade winds lock in and you just get a blank run. That's not unusual for this area. Forecasts can change, so keep an eye on it, but for now, there's nothing doing.

Rusty.
