The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for us over the next couple of weeks.

Honestly, it’s a grim start. We’re looking at a solid stretch of flat, poor conditions all the way through the end of July and into early August. The first week is basically a write-off, with nothing but zero scores and “poor surf conditions” across the board. You’ll be waiting a while.

The first real glimmer of hope doesn’t show up until Sunday the 9th of August. That afternoon, Anaehoomalu Bay_A-Bay (Big Island) finally sees a pulse of life. It’s not much – a 2 ft swell rolling in from the west, with a period of 13 seconds. That’s a long-period groundswell, which is a good sign for shape, but at a reef-and-point setup like this, it should wrap in nicely. The wind goes glassy in the afternoon, which is a massive positive for clean conditions. The combined energy is only 78 (moderate wave energy), so it’s not going to be a world-beater, but it’s surfable. Water temp is around 80°, which is about average for this time of year, so nothing unusual there.

The real standout, and the one to circle on your calendar, is the morning of Saturday the 8th of August. We’ve got a 2 ft west swell, period of 12 seconds, and the combined energy hits 110 (moderate wave energy). The wind is cross-on from the north at 6 mph, so it’s not perfect, but it’s manageable. This is the biggest swell of the whole run, and for a spot that’s “fairly exposed” to a WNW optimum, the direction is spot on. It’s consistent, too, so you won’t be staring at flat water. Just be aware that crowds are “sometimes” an issue here, so get out early.

The rest of the second week is more of the same – small, weak swells, mostly hanging around 1.0 ft to 2 ft, with periods around 11-13 seconds. The wind is often light and variable, with a few glassy windows, but the energy is low (most values in the tens or twenties). None of it is going to blow your mind. The best you can say is that by the 9th and 10th of August, there’s at least a tiny bit of motion in the water.

To sum it up: don’t bother until the 8th of August. That Saturday morning is your best bet for a decent session at A-Bay, with a clean, glassy Sunday afternoon as a backup. After that, it fades off again. It’s a lean period, but that’s the way it goes sometimes.

Rusty.
