Rivermouth_Wailuku Surf Forecast and Surf Report

Alright folks, Rusty here with a look at the local scene. Let’s be straight with you – we’ve only got one spot on the radar for this whole 16-day stretch, and it’s a tough one. Rivermouth_Wailuku is a reef break, and it's exposed to the swell, but the numbers are telling a pretty grim story overall.

The water temperature is sitting at 80°, which is about normal for this time of year, so no surprises there.

The first real chance of anything that isn't a total write-off comes around the morning of Tuesday, 28 July. The conditions are still marginal, with a 6ft swell from the east, but the wind clocks around to the north-northeast at 9 mph, putting it onshore. The combined energy is strong at 1241, so there’s some power in the water, but the wind is going to mess with the surface. It’s really only a question mark for the die-hards.

The next bit of hope comes mid-week on Wednesday, 29 July. The afternoon session offers a 7ft swell from the east-northeast with a period of 10 seconds, and the wind drops to a light northwesterly at 6 mph. That’s a gentle cross-onshore breeze, which will keep it reasonably clean. The energy is still strong (1042). This is the standout of the window. The swell size is getting up there, so it’s more for the experienced crew. The optimum swell direction is from the north-northeast, so this east-northeast swell is a little off-angle, but the drop in wind makes it the best bet. It’s a reef break, so it should handle the longer period okay.

After that, we’re back into a long, long stretch of poor conditions. The wind stays cross-onshore or onshore, and the wave quality is just not there. It’s a real grind from Thursday, 30 July, all the way through to the end of the window on Thursday, 6 August. The swell dips and rises, but the wind never cooperates, leaving us with choppy, lumpy, and generally unappealing surf. There’s a gap of about a week and a half with nothing really worth paddling out for.

So, to sum it up: the only real standout is Wednesday afternoon, 29 July, at Rivermouth_Wailuku. It’s not perfect, but it’s the cleanest we’ll see. The rest of the 16 days is a blank. Don’t hold your breath.

Rusty.
