The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the menu for the next couple of weeks.
To be straight with you, the outlook starts off pretty flat and stays that way for a long stretch. We’ve got a solid window of tiny to no surf from now through the end of July. From Saturday the 20th all the way through to Thursday the 31st, there’s day after day of either nothing or waves under a foot and a half, often with onshore or cross-onshore wind. That’s a solid 12-day gap where you’re better off fixing your dings or taking up golf.
The first real sign of life doesn’t show up until Saturday morning, August 1st, at Anaehoomalu Bay (A-Bay). We’re looking at a small pulse of WNW swell, barely 1ft, with a 14-second period. The wind is cross from the NNE at 9 mph, so it’ll be a little bumpy. Combined energy is low at 35. It’s really not worth paddling out for.
The standout window comes on Sunday, August 2nd. The morning still has a small 2ft WNW swell, but the period jumps to a very long 16 seconds – that’s real groundswell energy. Combined energy jumps to 231 (moderate), so there’s some push behind it. But here’s the kicker: by Sunday afternoon, the wind drops to glassy. Calm. Zero. That same 2ft swell from the W with a 14-second period will have combined energy of 322. That’s the best we’re going to see. For a reef and point like A-Bay, that long-period groundswell will wrap in nicely, and with glassy conditions, it’s going to be clean. The optimum swell direction is WNW, and this is coming from the W, so close enough. The water is sitting at 80°, which is about normal for this time of year.
A-Bay is a consistent spot and an intermediate wave. It can get crowded sometimes, so keep that in mind. The waves on Sunday afternoon won’t be big, but they’ll be clean and have some real shape. For a dedicated surfer, that’s the only real highlight in this whole 16-day run.
Rusty.
