The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a tough one. We’re looking at a long, dry spell with barely a ripple to get excited about for the first week and a half. The good news is, when the swell does show up, it’s got some potential, but you’re gonna need to be patient.
The first real chance of anything surfable comes late on Monday the 7th. Anaehoomalu Bay (A-Bay) will see a small 4 ft swell from the SW, with a period of 12 seconds. The wind is light and cross-onshore, so it’ll be a bit messy, but it’s a start. The water temp is sittin’ at a nice 82°, which is about normal for this time of year.
Tuesday the 8th sees a little more energy, with the swell bumping up to 5 ft from the WSW, still with that 10-second period. The combined energy hits 453 (moderate) in the morning, but the wind is still cross-onshore, so it’s not gonna be pristine. The afternoon glass-off might be the call, with the wind dropping to 3 mph and going straight offshore. That’s the best window in the first week, but it’s still a marginal one.
The middle of the week from Wednesday the 9th to the weekend is a total write-off. Swell drops to next to nothing, with combined energy in the double digits. There’s a brief moment on Thursday afternoon, the 10th, where it goes glassy, but the swell is a tiny 1.0 ft with a 16-second period – that’s just a long-period groundswell that won’t have any punch on a beach break. It’s basically a flat spell.
We don’t see any real action again until Monday the 14th, and even then it’s tiny. The only standout in the whole 16-day window is a bit of a long shot. On Wednesday the 16th, in the afternoon, we get a glassy 1 ft swell from the SW with a very long period of 18 seconds. The combined energy jumps to 112, which is weak but the best we’ll see. That long-period groundswell will be too straight for the beach, but if you can find a reef or a point that picks it up, it could be the one clean wave of the whole period. It’s not big, but it’s the only time the wind and swell align for a proper go.
Honestly, after that, it’s back to the doldrums. The forecast is consistent with a blank run for this area, so don’t get your hopes up. Stick to the dawn patrol on the 16th if you’re desperate.
Rusty.
