The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for this stretch.
To be straight with you, it’s gonna be a long, frustrating wait for any real juice at A-Bay. We’ve got a solid two-week stretch staring us down, and for the first week and a half, it’s flat or near-flat with hardly any energy in the water. The combined swell energy for most of that time is sitting below 100 (0 to 57), which is about as weak as it gets. You’ll be looking at a lot of glassy, clean, but completely flat afternoons, especially from Thursday afternoon onwards on the 30th of July through the 7th of August. Wind states are often glassy or light, so the water will look like a mirror, but there's nothing to ride. The only small pulses that show up are tiny—like 0.7ft to 1ft—and they’re usually from the N or W, which isn’t matching A-Bay’s preferred WNW direction for a decent wrap.
Things finally start to stir around the 8th of August, a Saturday. We see the combined energy jump into the three-digit range (150), with a 2ft swell from the west at 12 seconds. That’s a small, clean groundswell, but by Saturday afternoon it’s got glassy conditions and a 1 out of 10 score. It’s surfable, but very ordinary. The energy builds a little more into Monday the 10th of August, hitting a 3ft west swell at 14 seconds with 257 combined energy, but the wind is cross-onshore, so it’ll be lumpy. That pattern of small, marginal west swell hangs around until Thursday the 13th of August, where we see a 2ft west swell at 14 seconds, glassy in the afternoon, combined energy at 104. It’s surfable, but nothing to write home about.
The water temp is sittin’ at 80°F which is about 1°F warmer than normal for this time of year, so it’s a touch balmy but nothing wild.
If I had to pick the only real standout in this whole 16-day slog, it’d be the glassy windows with tiny, clean lines, but honestly, the best wave quality is just 'surfable but very ordinary'. There is no big, pumping swell on the horizon here. For expert surfers, there’s nothing over 8ft, so you’re safe. For beginners, the tiny stuff on offer in the second week isn't big enough to be a problem, but it's also not big enough to be fun.
In short, unless you’re desperate to paddle around on a lake-flat day, this is mostly a blank run. That’s pretty normal for this area in this season. We’ll have to wait and see if the models tighten up, but right now, pack a snorkel, not your shortboard.
Rusty.
